I need to implement the if condition in the below nawk command to process input file if the third column has more that three digit.Pls help with the command what i am doing wrong as it is not working.
inputfile.txt
123 | abc | 321456 | tre
213 | fbc | 342 | poi
outputfile.txt
123 | abc | 321### | tre
213 | fbc | 342 | poi
cat inputfile.txt | nawk 'BEGIN {FS="|"; OFS="|"} {if($3 > 3) $3=substr($3, 1, 3)"###" print}'
Try:
awk 'length($3) > 3 { $3=substr($3, 1, 3)"###" } 1 ' FS=\| OFS=\| test1.txt
This works with gawk:
awk -F '[[:blank:]]*\\\|[[:blank:]]*' -v OFS=' | ' '
$3 ~ /^[[:digit:]]{4,}/ {$3 = substr($3,1,3) "###"}
1
' inputfile.txt
It won't preserve the whitespace so you might want to pipe through column -t

I have a requirement to retrieve 239, 631 etc from the below output and store it in a variable in linux -- this is output of impala results..
+-----------------+
| organization_id |
+-----------------+
| 239 |
| 631 |
| 632 |
| 633 |
+-----------------+
below is the query I am running.
x=$(impala-shell -q "${ORG_ID}" -ki "${impalaserver}");
How to do it?
Could you please try following. This will be deleting duplicates for all Input_file(even a single id comes in 1 organization_id it will NOT br printed in other stanza then too)
your_command | awk -v s1="'" 'BEGIN{OFS=","} /---/{flag=""} /organization_id/{flag=1;getline;next} flag && !a[$2]++{val=val?val OFS s1 $2 s1:s1 $2 s1} END{print val}'
In case you need to print ids(which are coming in 1 stanza and could come in other stanza of organization_id then try following):
your_command | awk -v s="'" 'BEGIN{OFS=","} /---/{print val;val=flag="";delete a} /organization_id/{flag=1;getline;next} flag && !a[$2]++{val=val?val OFS s1 $2 s1:s1 $2 s1} END{if(val){print val}}'
What about this :
x=$(impala-shell -B -q "${ORG_ID}" -ki "${impalaserver}")
I just added the -B option which removes the pretty-printing and the header.
If you want comma-separated values you can pipe the result to tr :
echo $x | tr ' ' ','
I'd like to concatenate column2 until column4.
Example (first.txt):
|ID|column2|column3|column4|
|1 | a | b | c |
|2 | d | e | f |
To this (mynewfile.txt) :
ID|column2
1 | a b c
2 | d e f
This is my script in cygwin : $ awk '{print $2" "$3" "$4 }' first.txt > mynewfile.txt
Of course, it is not working out well.. How do I improve the script?
You need to set the field separator so that a pipe with optional whitespace around it is the field delimiter.
The pipe at the beginning of the line causes an empty field 1 before the pipe, so the ID is field 2, and columns 2-4 are fields 3-5. So it should be:
awk -F' *\\| *' 'NR == 1 {print "ID|column2|"} NR > 1 {printf("%d | %s %s %s |\n", $2, $3, $4, $5)}' first.txt > mynewfile.txt
Not especially general GNU sed method:
sed 's/^[|]//;1s/2.*/2/;1!{s/|/ /g2;s/ */ /2g}' first.txt
Output:
ID|column2
1 | a b c
2 | d e f
I am having a single file in which it contains 1st and 2nd column with item code and name, then from 3rd to 12th column which contains its 10 days consumption quantity continuously.
Now i need to convert that into 10 different files. In each the 1st and 2nd column should be the same item code and item name and the 3rd column will contain the consumption quantity of one day in each..
input file:
Code | Name | Day1 | Day2 | Day3 |...
10001 | abcd | 5 | 1 | 9 |...
10002 | degg | 3 | 9 | 6 |...
10003 | gxyz | 4 | 8 | 7 |...
I need the Output in different file as
file 1:
Code | Name | Day1
10001 | abcd | 5
10002 | degg | 3
10003 | gxyz | 4
file 2:
Code | Name | Day2
10001 | abcd | 1
10002 | degg | 9
10003 | gxyz | 8
file 3:
Code | Name | Day3
10001 | abcd | 9
10002 | degg | 6
10003 | gxyz | 7
and so on....
I wrote a code like this
awk 'BEGIN { FS = "\t" } ; {print $1,$2,$3}' FILE_NAME > file1;
awk 'BEGIN { FS = "\t" } ; {print $1,$2,$4}' FILE_NAME > file2;
awk 'BEGIN { FS = "\t" } ; {print $1,$2,$5}' FILE_NAME > file3;
and so on...
Now i need to write it with in a 'for' or 'while' loop which would be faster...
I dont know the exact code, may be like this..
for (( i=3; i<=NF; i++)) ; do awk 'BEGIN { FS = "\t" } ; {print $1,$2,$i}' input.tsv > $i.tsv; done
kindly help me to get the output as i explained.
If you absolutely need to to use a loop in Bash, then your loop can be fixed like this:
for ((i = 3; i <= 10; i++)); do awk -v field=$i 'BEGIN { FS = "\t" } { print $1, $2, $field }' input.tsv > file$i.tsv; done
But it would be really better to solve this using pure awk, without shell at all:
awk -v FS='\t' '
NR == 1 {
for (i = 3; i < NF; i++) {
fn = "file" (i - 2) ".txt";
print $1, $2, $i > fn;
print "" >> fn;
}
}
NR > 2 {
for (i = 3; i < NF; i++) {
fn = "file" (i - 2) ".txt";
print $1, $2, $i >> fn;
}
}' inputfile
That is, when you're on the first record,
create the output files by writing the header line and a blank line (as in specified in your question).
For the 3rd and later records, append to the files.
Note that the code in your question suggests that the fields in the file are separated by tabs, but the example files seem to use | padded with variable number of spaces. It's not clear which one is your actual case. If it's really tab-separated, then the above code will work. If in fact it's as the example inputs, then change the first line to this:
awk -v OFS=' | ' -v FS='[ |]+' '
bash + cut solution:
input.tsv test content:
Code | Name | Day1 | Day2 | Day3
10001 | abcd | 5 | 1 | 9
10002 | degg | 3 | 9 | 6
10003 | gxyz | 4 | 8 | 7
day_splitter.sh script:
#!/bin/bash
n=$(cat $1 | head -1 | awk -F'|' '{print NF}') # total number of fields
for ((i=3; i<=$n; i++))
do
fn="Day"$(($i-2)) # file name containing `Day` number
$(cut -d'|' -f1,2,$i $1 > $fn".txt")
done
Usage:
bash day_splitter.sh input.tsv
Results:
$cat Day1.txt
Code | Name | Day1
10001 | abcd | 5
10002 | degg | 3
10003 | gxyz | 4
$cat Day2.txt
Code | Name | Day2
10001 | abcd | 1
10002 | degg | 9
10003 | gxyz | 8
$cat Day3.txt
Code | Name | Day3
10001 | abcd | 9
10002 | degg | 6
10003 | gxyz | 7
In pure awk:
$ awk 'BEGIN{FS=OFS="|"}{for(i=3;i<=NF;i++) {f="file" (i-2); print $1,$2,$i >> f; close(f)}}' file
Explained:
$ awk '
BEGIN {
FS=OFS="|" } # set delimiters
{
for(i=3;i<=NF;i++) { # loop the consumption fields
f="file" (i-2) # create the filename
print $1,$2,$i >> f # append to target file
close(f) } # close the target file
}' file
I have a .txt file with strings in arrays which looks like these:
id | String1 | String2 | Counts
1 | Abc | Abb | 0
2 | Cde | Cdf | 0
And i want to add counts, so i need to replace last digit, but i need to change it only for the one line.
I am getting new needed value by this function:
$(awk -F "|" -v i=$idOpen 'FNR == i { gsub (" ", "", $0); print $4}' filename)"
And them I want to replace it with new value, which will be bigger for 1.
And im doing it right in there.
counts=(("$(awk -F "|" -v i=$idOpen 'FNR == i { gsub (" ", "", $0); print $4}' filename)"+1))
Where IdOpen is an id of the array, where i need to replace string.
So i have tried to replace the whole array by these:
counter="$(awk -v i=$idOpen 'BEGIN{FNqR == i}{$7+=1} END{ print $0}' bookmarks)"
N=$idOpen
sed -i "{N}s/.*/${counter}" bookmarks
But it doesn't work!
So is there a way to replace only last string with value which i have got earlier?
As result i need to get:
id | String1 | String2 | Counts
1 | Abc | Abb | 1 # if idOpen was 1 for 1 time
2 | Cde | Cdf | 2 # if idOpen was 2 for 2 times
And the last number will be increased by 1 everytime when i will activate these commands.
awk solution:
setting idOpen variable(for ex. 2):
idOpen=2
awk -F'|' -v i=$idOpen 'NR>1{if($1 == i) $4=" "$4+1}1' OFS='|' file > tmp && mv tmp file
The output(after executing the above command twice):
cat file
id | String1 | String2 | Counts
1 | Abc | Abb | 0
2 | Cde | Cdf | 2
NR>1 - skipping the header line
Formatting the output based on the maximum column length. How can I achieve this?
Shell script or any tools is fine.
Input
| date | ID | Typ | Actn |
| 11/29/13 | ID660011 | DP | A |
| 11/29/13 | ID6600123 | DP | A |
Output
| date | ID | Typ| Actn|
| 11/29/13| ID660011 | DP | A |
| 11/29/13| ID6600123| DP | A |
EDIT:
If I use column -t, these are the errors:
$ column -t -s'|' -o'|'
input_file .feature > input_file _check.feature
column: illegal option -- o
usage: column [-tx] [-c columns] [-s sep] [file ...]
$ echo $SHELL /usr/local/bin/bash
$ column -t input_file .feature > input_file _check.feature column:
line too long
On your shell terminal, try this one:
$ awk '
{
for(i=1;i<=NF;i++)
printf("%-40s%c", $i, (i==NF) ? ORS : "")
}' FS=, file.txt
