Paste hundreds of file with specific pattern name in bash/awk/c - bash

I have 500 files and I want to merge them by adding columns.
My first file
3
4
1
5
My second file
7
1
4
2
Output should look like
3 7
4 1
1 4
5 2
But I have 500 files (sum_1.txt, sum_501.txt until sum_249501.txt), so I must have 500 column, so It will be very frustrating to write 500 file names.
Is it possible to do this easier? I try this, but it not makes 500 columns, but instead it makes a lot of rows
#!/bin/bash
file_name="sum"
tmp=$(mktemp) || exit 1
touch ${file_name}_calosc.txt
for first in {1..249501..500}
do
paste -d ${file_name}_calosc.txt ${file_name}_$first.txt >> ${file_name}_calosc.txt
done

Something like this (untested) should work regardless of how many files you have:
awk '
BEGIN {
for (i=1; i<=249501; i+=500) {
ARGV[ARGC++] = "sum_" i
}
}
{ vals[FNR] = (NR==FNR ? "" : vals[FNR] OFS) $0 }
END {
for (i=1; i<=FNR; i++) {
print vals[i]
}
}
'
It'd only fail if the total content of all the files was too big to fit in memory.

Your command says to paste two files together; to paste more files, give more files as arguments to paste.
You can paste a number of files together like
paste sum_{1..249501..500}_calosc.txt > sum_calosc.txt
but if the number of files is too large for paste, or the resulting command line is too long, you may still have to resort to temporary files.
Here's an attempt to paste 25 files at a time, then combine the resulting 20 files in a final big paste.
#!/bin/bash
d=$(mktemp -d -t pastemanyXXXXXXXXXXX) || exit
# Clean up when done
trap 'rm -rf "$d"; exit' ERR EXIT
for ((i=1; i<= 249501; i+=500*25)); do
printf -v dest "paste%06i.txt" "$i"
for ((j=1, k=i; j<=500; j++, k++)); do
printf "sum_%i.txt\n" "$k"
done |
xargs paste >"$d/$dest"
done
paste "$d"/* >sum_calosc.txt
The function of xargs is to combine its inputs into a single command line (or more than one if it would otherwise be too long; but we are specifically trying to avoid that here, because we want to control exactly how many files we pass to paste).

How to pass multiple files with variable filenames to the paste command

Usually when we wish to concatenate several files column wise and the filenames of the files are just consecutive increasing integers we can do the following:
#Imagine I have 10 files
paste {1..10} > out
However, I'm currently working on a script in which the ranges are variables, so I want to be able to do something like this
first=1
last=10
paste {"${first}".."${last}"} > out
This doesn't work as variables can't be correctly expanded within the curly braces. Is there an alternative syntax I can use to achieve the same result?
If you don't want to use eval, you can use seq(1):
seq -s ' ' "$first" "$last"
Like so:
paste $(seq -s ' ' "$first" "$last") > out
Once upon a time a needed a seq like function but a way faster, so i made this
# Create sequence like {0..X}
cnt () { printf -v N %$1s; N=(${N// / 1}); printf "${!N[*]}"; }
$ cnt 5
0 1 2 3 4
And if we modify it a bit
# Create sequence like {X..Y}
cnt () { printf -v N %$2s; N=(${N// / 1}); N=(${!N[#]}); printf "${N[*]:$1} ${#N[#]}"; }
$ cnt 7 11
7 8 9 10 11

while loops in parallel with input from splited file

I am stuck on that. So I have this while-read loop within my code that is taking so long and I would like to run it in many processors. But, I'd like to split the input file and run 14 loops (because I have 14 threads), one for each splited file, in parallel. Thing is that I don't know how to tell the while loop which file to get and work with.
For example, in a regular while-read loop I would code:
while read line
do
<some code>
done < input file or variable...
But in this case I would like to split the above input file in 14 files and run 14 while loops in parallel, one for each splited file.
I tried :
split -n 14 input_file
find . -name "xa*" | \
parallel -j 14 | \
while read line
do
<lot of stuff>
done
also tried
split -n 14 input_file
function loop {
while read line
do
<lot of stuff>
done
}
export -f loop
parallel -j 14 ::: loop
But neither I was able to tell which file would be the input to the loop so parallel would understand "take each of those xa* files and place into individual loops in parallel"
An example of the input file (a list of strings)

LOBZ01000025.54942.57580
EDIT
This is the code.
The output is a table (741100 lines) with some statistics regarding DNA sequences alignments already made.
The loop takes an input_file (no broken lines, varies from 500 to ~45000 lines, 800Kb) with DNA sequence acessions, reads it line-by-line and look for each correspondent full taxonomy for those acessions in a databank (~45000 lines). Then, it does a few sums/divisions. Output is a .tsv and looks like this (an example for sequence "KF625180.1.1799"):
Rate of taxonomies for this sequence in %: KF625180.1.1799 D_6__Bacillus_atrophaeus
Taxonomy %aligned number_ocurrences_in_the_alignment num_ocurrences_in_databank %alingment/databank
D_6__Bacillus_atrophaeus 50% 1 20 5%
D_6__Bacillus_amyloliquefaciens 50% 1 154 0.649351%
$ head input file

LOBZ01000025.54942.57580
Two additional files are also used inside the loop. They are not the loop input.
1) a file called alnout_file that only serves for finding how many hits (or alignments) a given sequence had against the databank. It was also previously made outside this loop. It can vary in the number of lines from hundreads to thousands. Only columns 1 and 2 matters here. Column1 is the name of the sequence and col2 is the name of all sequences it matched in the databnk. It looks like that:
$ head alnout_file
KF625180.1.1799 KF625180.1.1799 100.0 431 0 0 1 431 1 431 -1 0
KF625180.1.1799 KP143082.1.1457 99.3 431 1 2 1 431 1 429 -1 0
KP143082.1.1457 KF625180.1.1799 99.3 431 1 2 1 429 1 431 -1 0
2) a databank .tsv file containing ~45000 taxonomies correspondent to the DNA sequences. Each taxonomy is in one line:
$ head taxonomy.file.tsv
KP143082.1.1457 D_0__Bacteria;D_1__Firmicutes;D_2__Bacilli;D_3__Bacillales;D_4__Bacillaceae;D_5__Bacillus;D_6__Bacillus_amyloliquefaciens
KF625180.1.1799 D_0__Bacteria;D_1__Firmicutes;D_2__Bacilli;D_3__Bacillales;D_4__Bacillaceae;D_5__Bacillus;D_6__Bacillus_atrophaeus
So, given sequence KF625180.1.1799. I previously aligned it against a databank containing ~45000 other DNA sequences and got an output whis has all the accessions to sequences that it matched. What the loop does is that it finds the taxonomies for all those sequences and calculates the "statistics" I mentionded previously. Code does it for all the DNA-sequences-accesions I have.
TAXONOMY=path/taxonomy.file.tsv
while read line
do
#find hits
hits=$(grep $line alnout_file | cut -f 2)
completename=$(grep $line $TAXONOMY | sed 's/D_0.*D_4/D_4/g')
printf "\nRate of taxonomies for this sequence in %%:\t$completename\n"
printf "Taxonomy\t%aligned\tnumber_ocurrences_in_the_alignment\tnum_ocurrences_in_databank\t%alingment/databank\n"
#find hits and calculate the frequence (%) of the taxonomy in the alignment output
# ex.: Bacillus_subtilis 33
freqHits=$(grep "${hits[#]}" $TAXONOMY | \
cut -f 2 | \
awk '{a[$0]++} END {for (i in a) {print i, "\t", a[i]/NR*100, "\t", a[i]}}' | \
sed -e 's/D_0.*D_5/D_5/g' -e 's#\s\t\s#\t#g' | \
sort -k2 -hr)
# print frequence of each taxonomy in the databank
freqBank=$(while read line; do grep -c "$line" $TAXONOMY; done < <(echo "$freqHits" | cut -f 1))
#print cols with taxonomy and calculations
paste <(printf %s "$freqHits") <(printf %s "$freqBank") | awk '{print $1,"\t",$2"%","\t",$3,"\t",$4,"\t",$3/$4*100"%"}'
done < input_file
It is a lot of greps and parsing so it takes about ~12h running in one processor for doing it to all the 45000 DNA sequence accessions. The, I would like to split input_file and do it in all the processors I have (14) because it would the time spend in that.
Thank you all for being so patient with me =)
You are looking for --pipe. In this case you can even use the optimized --pipepart (version >20160621):
export TAXONOMY=path/taxonomy.file.tsv
doit() {
while read line
do
#find hits
hits=$(grep $line alnout_file | cut -f 2)
completename=$(grep $line $TAXONOMY | sed 's/D_0.*D_4/D_4/g')
printf "\nRate of taxonomies for this sequence in %%:\t$completename\n"
printf "Taxonomy\t%aligned\tnumber_ocurrences_in_the_alignment\tnum_ocurrences_in_databank\t%alingment/databank\n"
#find hits and calculate the frequence (%) of the taxonomy in the alignment output
# ex.: Bacillus_subtilis 33
freqHits=$(grep "${hits[#]}" $TAXONOMY | \
cut -f 2 | \
awk '{a[$0]++} END {for (i in a) {print i, "\t", a[i]/NR*100, "\t", a[i]}}' | \
sed -e 's/D_0.*D_5/D_5/g' -e 's#\s\t\s#\t#g' | \
sort -k2 -hr)
# print frequence of each taxonomy in the databank
freqBank=$(while read line; do grep -c "$line" $TAXONOMY; done < <(echo "$freqHits" | cut -f 1))
#print cols with taxonomy and calculations
paste <(printf %s "$freqHits") <(printf %s "$freqBank") | awk '{print $1,"\t",$2"%","\t",$3,"\t",$4,"\t",$3/$4*100"%"}'
done
}
export -f doit
parallel -a input_file --pipepart doit
This will chop input_file into 10*ncpu blocks (where ncpu is the number of CPU threads), pass each block to doit, run ncpu jobs in parallel.
That said I think your real problem is spawning too many programs: If you rewrite doit in Perl or Python I will expect you will see a major speedup.
As an alternative I threw together a quick test.
#! /bin/env bash
mkfifo PIPELINE # create a single queue
cat "$1" > PIPELINE & # supply it with records
{ declare -i cnt=0 max=14
while (( ++cnt <= max )) # spawn loop creates worker jobs
do printf -v fn "%02d" $cnt
while read -r line # each work loop reads common stdin...
do echo "$fn:[$line]"
sleep 1
done >$fn.log 2>&1 & # these run in background in parallel
done # this one exits
} < PIPELINE # *all* read from the same queue
wait
cat [0-9][0-9].log
Doesn't need split, but does need a mkfifo.
Obviously, change the code inside the internal loop.
This answers what you asked, namely how to process in parallel the 14 files you get from running split. However, I don't think it is the best way of doing whatever it is that you are trying to do - but we would need some answers from you for that.
So, let's make a million line file and split it into 14 parts:
seq 1000000 > 1M
split -n 14 1M part-
That gives me 14 files called part-aa through part-an. Now your question is how to process those 14 parts in parallel - (read the last line first):
#!/bin/bash
# This function will be called for each of the 14 files
DoOne(){
# Pick up parameters
job=$1
file=$2
# Count lines in specified file
lines=$(wc -l < "$file")
echo "Job No: $job, file: $file, lines: $lines"
}
# Make the function above known to processes spawned by GNU Parallel
export -f DoOne
# Run 14 parallel instances of "DoOne" passing job number and filename to each
parallel -k -j 14 DoOne {#} {} ::: part-??
Sample Output
Job No: 1, file: part-aa, lines: 83861
Job No: 2, file: part-ab, lines: 72600
Job No: 3, file: part-ac, lines: 70295
Job No: 4, file: part-ad, lines: 70295
Job No: 5, file: part-ae, lines: 70294
Job No: 6, file: part-af, lines: 70295
Job No: 7, file: part-ag, lines: 70295
Job No: 8, file: part-ah, lines: 70294
Job No: 9, file: part-ai, lines: 70295
Job No: 10, file: part-aj, lines: 70295
Job No: 11, file: part-ak, lines: 70295
Job No: 12, file: part-al, lines: 70294
Job No: 13, file: part-am, lines: 70295
Job No: 14, file: part-an, lines: 70297
You would omit the -k argument to GNU Parallel normally - I only added it so the output comes in order.
I think that using a bunch of grep and awk commands is the wrong approach here - you would be miles better off using Perl, or awk. As you have not provided any sample files I generated some using this code:
#!/bin/bash
for a in {A..Z} {0..9} ; do
for b in {A..Z} {0..9} ; do
for c in {A..Z} {0..9} ; do
echo "${a}${b}${c}"
done
done
done > a
# Now make file "b" which has the same stuff but shuffled into a different order
gshuf < a > b
Note that there are 26 letters in the alphabet, so if I add the digits 0..9 to the letters of the alphabet, I get 36 alphanumeric digits and if I nest 3 loops of that I get 36^3 or 46,656 lines which matches your file sizes roughly. File a now looks like this:
AAA
AAB
AAC
AAD
AAE
AAF
File b looks like this:
UKM
L50
AOC
79U
K6S
6PO
12I
XEV
WJN
Now I want to loop through a finding the corresponding line in b. First, I use your approach:
time while read thing ; do grep $thing b > /dev/null ; done < a
That takes 9 mins 35 seconds.
If I now exit grep on the first match, on average I will find it in the middle, which means the time will be halved since I won't continue to needlessly read b after I find what I want.
time while read thing ; do grep -m1 $thing b > /dev/null ; done < a
That improves the time down to 4 mins 30 seconds.
If I now use awk to read the contents of b into an associative array (a.k.a. hash) and then read the elements of a and find them in b like this:
time awk 'FNR==NR{a[$1]=$1; next} {print a[$1]}' b a > /dev/null
That now runs in 0.07 seconds. Hopefully you get the idea of what I am driving at. I expect Perl would do this in the same time and also provide more expressive facilities for the maths in the middle of your loop too.
I hope this small script helps you out:
function process {
while read line; do
echo "$line"
done < $1
}
function loop {
file=$1
chunks=$2
dir=`mktemp -d`
cd $dir
split -n l/$chunks $file
for i in *; do
process "$i" &
done
rm -rf $dir
}
loop /tmp/foo 14
It runs the process loop on the specified file with the specified number of chunks (without splitting lines) in parallel (using & to put each invocation in the background). I hope it gets you started.
This can do the job for You, I am not familiar with parallel instead using native bash spawning processes &:
function loop () {
while IFS= read -r -d $'\n'
do
# YOUR BIG STUFF
done < "${1}"
}
arr_files=(./xa*)
for i in "${arr_files[#]}"
do loop "${i}" &
done
wait

Sorting on multiple columns w/ an output file per key

I'm uncertain as to how I can use the until loop inside a while loop.
I have an input file of 500,000 lines that look like this:
9 1 1 0.6132E+02
9 2 1 0.6314E+02
10 3 1 0.5874E+02
10 4 1 0.5266E+02
10 5 1 0.5571E+02
1 6 1 0.5004E+02
1 7 1 0.5450E+02
2 8 1 0.5696E+02
11 9 1 0.6369E+02
.....
And what I'm hoping to achieve is to sort the numbers in the first column in numerical order such that I can pull all the similar lines (eg. lines that start with the same number) into new text files "cluster${i}.txt". From there I want to sort the fourth column of ("cluster${i}.txt") files in numerical order. After sorting I would like to write the first row of each sorted "cluster${i}.txt" file into a single output file. A sample output of "cluster1.txt" would like this:
1 6 1 0.5004E+02
1 7 1 0.5450E+02
1 11 1 0.6777E+02
....
as well as an output.txt file that would look like this:
1 6 1 0.5004E+02
2 487 1 0.3495E+02
3 34 1 0.0344E+02
....
Here is what I've written:
#!/bin/bash
input='input.txt'
i=1
sort -nk 1 $input > 'temp.txt'
while read line; do
awk -v var="$i" '$1 == var' temp.txt > "cluster${i}.txt"
until [[$i -lt 20]]; do
i=$((i+1))
done
done
for f in *.txt; do
sort -nk 4 > temp2.txt
head -1 temp2.txt
rm temp2.txt
done > output.txt
This only takes one line, if your sort -n knows how to handle exponential notation:
sort -nk 1,4 <in.txt | awk '{ of="cluster" $1 ".txt"; print $0 >>of }'
...or, to also write the first line for each index to output.txt:
sort -nk 1,4 <in.txt | awk '
{
if($1 != last) {
print $0 >"output.txt"
last=$1
}
of="cluster" $1 ".txt";
print $0 >of
}'
Consider using an awk implementation -- such as GNU awk -- which will cache file descriptors, rather than reopening each output file for every append; this will greatly improve performance.
By the way, let's look at what was wrong with the original script:
It was slow. Really, really slow.
Starting a new instance of awk 20 times for every line of input (because the whole point of while read is to iterate over individual lines, so putting an awk inside a while read is going to run awk at least once per line) is going to have a very appreciable impact on performance. Not that it was actually doing this, because...
The while read line outer loop was reading from stdin, not temp.txt or input.txt.
Thus, the script was hanging if stdin didn't have anything written on it, or wasn't executing the contents of the loop at all if stdin pointed to a source with no content like /dev/null.
The inner loop wasn't actually processing the line read by the outer loop. line was being read, but all of temp.txt was being operated on.
The awk wasn't actually inside the inner loop, but rather was inside the outer loop, just before the inner loop. Consequently, it wasn't being run 20 times with different values for i, but run only once per line read, with whichever value for i was left over from previously executed code.
Whitespace is important to how commands are parsed. [[foo]] is wrong; it needs to be [[ foo ]].
To "fix" the inner loop, to do what I imagine you meant to write, might look like this:
# this is slow and awful, but at least it'll work.
while IFS= read -r line; do
i=0
until [[ $i -ge 20 ]]; do
awk -v var="$i" '$1 == var' <<<"$line" >>"cluster${i}.txt"
i=$((i+1))
done
done <temp.txt
...or, somewhat better (but still not as good as the solution suggested at the top):
# this is a somewhat less awful.
for (( i=0; i<=20; i++ )); do
awk -v var="$i" '$1 == var' <temp.txt >"cluster${i}.txt"
head -n 1 "cluster${i}.txt"
done >output.txt
Note how the redirection to output.txt is done just once, for the whole loop -- this means we're only opening the file once.

Detect if a series of numbers is sequential in bash/awk

So I have a series of scripts that generate intermediary text files along the way as a means of storing information across different scripts. Essentially the scripts detect rows within data that have been approved by the user for removal. The line numbers that are to be removed from the source file are stored in a file.
For example, say I have a source data file like this:
a1,b1,c1,d1
a2,b2,c2,d2
a3,b3,c3,d3
a4,b4,c4,d4
a5,b5,c5,d5
a6,b6,c6,d6
a7,b7,c7,d7
And the intermediary file would contain something like this:
1 3 4 5 6
Which would result, when the script is run, in an output data file as follows:
a2,b2,c2,d2
a7,b7,c7,d7
This all works fine, there is nothing to fix in this code. The problem is, when I'm dealing with actual data files sometimes there are literally thousands of numbers stored in the intermediary file for removal. This means I can't use a loop, because it will take a massive amount of time, and my current method of using sed gets overloaded with a error: too many arguments. Many of the line numbers are consecutive, so here's where I get to my question:
Is there a way in bash or awk to detect whether a series of space-separated numbers are consecutive?
I can sort out everything beyond that, I'm just stumped on how I could do this in one/a series of step(s). My plan, if I can detect consecutive values, is to change the intermediary file from:
1 3 4 5 6
To:
1 3-6
And then I'll be able to write code that will run on each range of values in a more manageable way.
If possible I'd like to avoid looping through each value and checking individually whether or not it's one step above the previous value, since I'm dealing with tens of thousands of numbers in a list.
If this is not possible in bash/awk, is there another way to accomplish this task to reduce the overall number of arguments passed to my script and greatly reduce the chances of encountering an error for too many arguments?
What about this?
BEGIN {
getline < "intermediate.txt"
split($0, skippedlines, " ")
skipindex = 1
}
{
if (skippedlines[skipindex] == NR)
++skipindex;
else
print
}
Use cat, join, and cut:
Files infile and ids:
a1,b1,c1,d1 1
a2,b2,c2,d2 3
a3,b3,c3,d3 4
a4,b4,c4,d4 5
a5,b5,c5,d5 6
a6,b6,c6,d6
a7,b7,c7,d7
Removal of selected lines:
$ join -v 2 ids <(cat -n infile) | cut -f 2 -d ' '
a2,b2,c2,d2
a7,b7,c7,d7
What's going on:
First, the initial file receives an id on each line, with cat -n infile;
then, the resulting file is joined on the first column with the file holding the ids;
only non-matching lines from second file are printed -- join -v 2;
the first column, with the ids, is removed;
and, it's a neat shell one-liner (:
In case your file with ids is written as an unique line, you can still make use of the above one-liner, simply adding a translation on the file with ids, as follows:
$ join -v 2 <(tr ' ' '\n' ids) <(cat -n infile) | cut -f 2 -d ' '
#jmihalicza's answer nicely uses awk to solve the whole problem of selecting the lines from source file that match those in the intermediate file. For completeness, the following awk program reduces the list of individual line numbers to ranges, where possible, which I think answers the original question:
{ for (j = 1; j <= NF; j++) {
lin[i++] = $j;
}
}
END {
start = lin[0];
j = 1;
while (j <= i) {
end = start
while (lin[j] == (lin[j-1]+1)) {
end = lin[j++];
}
if ((end+0) > (start+0)) {
printf "%d-%d ",start,end
} else {
printf "%d ",start
}
start = lin[j++];
}
}
Given this script, which I've called merge.awk and a file testlin.txt as follows:
1 3 4 5 6 9 10 11 13 15
... we can do this:
$ awk -f merge.awk <testlin.txt
1 3-6 9-11 13 15
This might work for you (GNU sed):
sed -r 's/\S+/&d/g;s/\s+/\n/g' intermediate_file | sed -f - source_file
Change the intermediate file into a sed script.

Paste column to existing file in a loop

I am using the paste command in a bash loop to add new columns to a CSV-file. I would like to reuse the CSV-file. Currently I am using a temporary file to accomplish this:
while [ $i -le $max ]
do
# create text from grib2
wgrib2 -d 1.$(($i+1)) -no_header myGribFile.grb2 -text tmptxt.txt
#paste to temporary file
paste -d, existingfile.csv tmptxt.txt > tmpcsv.csv
#overwrite old csv with new csv
mv tmpcsv.csv existingfile.csv

After adding some columns the copy is getting slow, because the file is becoming bigger and bigger (every tmptxt.txt has about 2 MB, adding to approx 100 MB).
A tmptxt.txt is a plain txt-file with one column and one value per row:
1
2
3
.
.
The existingfile.csv would then be
1,1,x
2,2,y
3,3,z
.,.,.
.,.,.
Is there any way to use the paste command to add a column to an existing file? Or is there any other way?
Thanks
Would it be feasible to split the operation in 2 ? One step for generating all the intermediate files; and another for generating all the final output file. The idea is to avoid rereading and rewriting over and over the final file.
The changes to the script would be something like this:
while [ $i -le $max ]
do
n=$(printf "%05d" $i) # to preserve lexical order if $max > 9
# create text from grib2
wgrib2 -d 1.$(($i+1)) -no_header myGribFile.grb2 -text tmptxt$n.txt
((i++))
done
#make final file
paste -d, existingfile.csv tmptxt[0-9]*.txt > tmpcsv.csv
#overwrite old csv with new csv
mv tmpcsv.csv existingfile.csv
Assuming the number of lines output by the program is constant and is equal to number of lines in existingfile.csv (which should be the case since you are using paste)
Disclaimer: I'm not exactly sure if this would speed things up (depending on whether io redirection >> writes to the file exactly once or not). Anyway give it a try and let me know.
So the basic idea is
append the output in one go after the loop is done (note the change: wgrib now prints to - which is stdout)
use awk to move every linenum rows (linenum being the number of lines in existingfile.csv) to the end to the first linenum rows
Save to tempcsv.csv (because I can't find a way to save in the same file)
rename to / overwrite existingfile.csv
.
while [ $i -le $max ]; do
# create text from grib2
wgrib2 -d 1.$(($i+1)) -no_header myGribFile.grb2 -text -
((i++))
done >> existingfile.csv
awk -v linenum=4 '
{ array[FNR%linenum]=array[FNR%linenum]","$0 }
END { for(i=1;i<linenum;i++) print array[i%linenum] }
' existingfile.csv > tempcsv.csv
mv tempcsv.csv existingfile.csv
If this is how I imagine it would work (internally), you should have 2 writes to existingfile.csv instead of $max number of writes. So hopefully this would speed things up.
