How to add duplicates lines to a file using Unix - shell

I want to add duplicate lines I have tried but not able to get the desired output
I have used sed but end up with all lines duplicated (below code)
sed 'p' Data.txt > Output.txt
I have tried with awk but end up with all lines duplicated (below code)
while read line; do
commacount=`echo $line|tr ',' '\n'|wc -l`
atcount=`echo $line|tr '#' '\n'|wc -l`
echo $commacount,$atcount
if [ "$commacount == '8' && $atcount == '3'" ]; then
{
awk '{print $0}1' Data.txt > tmp
}
else
{
awk '{print $0}' Data.txt > tmp
}
fi
done < Data.txt

Is there anyway that I can get the above output.
I appreciate any help/suggestion.
Thanks

Do you want duplicate lines which have 8 non-empty columns?
Try this:
awk -F',+' 'NF==8;1' file.txt


Here's the sed version:
sed '/^[0-9-]\{10\}T[0-9]\{2\}:[0-9]\{2\}:00+10/p' file.txt

How to extract phone number and Pin from each text line

Sample Text from the log file
2021/08/29 10:25:37 20210202GL1 Message Params [userid:user1] [timestamp:20210829] [from:TEST] [to:0214736848] [text:You requested for Pin reset. Your Customer ID: 0214736848 and PIN: 4581]
2021/08/27 00:03:18 20210202GL2 Message Params [userid:user1] [timestamp:20210827] [from:TEST] [to:0214736457] [text:You requested for Pin reset. Your Customer ID: 0214736457 and PIN: 6193]
2021/08/27 10:25:16 Thank you for joining our service; Your ID is 0214736849 and PIN is 5949
Other wording and formatting can change but ID and PIN don't change
Expected out put for each line
0214736848#4581
0214736457#6193
0214736849#5949
Below is what I have tried out using bash though am currently able to extract only the numeric values
while read p; do
NUM=''
counter=1;
text=$(echo "$p" | grep -o -E '[0-9]+')
for line in $text
do
if [ "$counter" -eq 1 ] #if is equal to 1
then
NUM+="$line" #concatenate string
else
NUM+="#$line" #concatenate string
fi
let counter++ #Increment counter
done
printf "$NUM\n"
done < logfile.log
Current output though not the expected.
2021#08#29#00#03#18#20210202#2#1#20210826#0214736457#0214736457#6193
2021#08#27#10#25#37#20210202#1#1#20210825#0214736848#0214736848#4581
2021#08#27#10#25#16#0214736849#5949

Another variation using gawk and 2 capture groups, matching 1 or more digits per group:
awk '
match($0, /ID: ([0-9]+) and PIN: ([0-9]+)/, m) {
print m[1]"#"m[2]
}
' file
Output
0214736848#4581
0214736457#6193
For the updated question, you could either match : or is if you want a more precise match, and the capture group values will be 2 and 4.
awk '
match($0, /ID(:| is) ([0-9]+) and PIN(:| is) ([0-9]+)/, m) {
print m[2]"#"m[4]
}
' file
Output
0214736848#4581
0214736457#6193
0214736849#5949

Using sed capture groups you can do:
sed 's/.* Your Customer ID: \([0-9]*\) and PIN: \([0-9]*\).*/\1#\2/g' file.txt

With your shown samples please try following awk code, you could simple do it with using different field separators. Simple explanation would be, making Customer ID: OR and PIN: OR ]$ as field separators and then keeping them in mind printing only 2nd and 3rd fields along with # as per required output by OP.
awk -v FS='Customer ID: | and PIN: |]$' '{print $2"#"$3}' Input_file

With bash and a regex:
while IFS='] ' read -r line; do
[[ "$line" =~ ID:\ ([^\ ]+).*PIN:\ ([^\ ]+)] ]]
echo "${BASH_REMATCH[1]}#${BASH_REMATCH[2]}"
done <file
Output:
0214736848#4581
0214736457#6193

Given the updated input in your question then using any sed in any shell on every Unix box:
$ sed 's/.* ID[: ][^0-9]*\([0-9]*\).* PIN[: ][^0-9]*\([0-9]*\).*/\1#\2/' file
0214736848#4581
0214736457#6193
0214736849#5949
Original answer:
Using any awk in any shell on every Unix box:
$ awk -v OFS='#' '{print $18, $21+0}' file
0214736848#4581
0214736457#6193

Alternating output in bash for loop from two grep

I'm trying to search through files and extract two pieces of relevant information every time they appear in the file. The code I currently have:
#!/bin/bash
echo "Utilized reads from ustacks output" > reads.txt
str1="utilized reads:"
str2="Parsing"
for file in /home/desaixmg/novogene/stacks/sample01/conda_ustacks.o*; do
reads=$(grep $str1 $file | cut -d ':' -f 3
samples=$(grep $str2 $file | cut -d '/' -f 8
echo $samples $reads >> reads.txt
done
It is doing each line for the file (the files have varying numbers of instances of these phrases) and gives me the output per row for each file:
PopA_15.fq 1081264
PopA_16.fq PopA_17.fq 1008416 554791
PopA_18.fq PopA_20.fq PopA_21.fq 604610 531227 595129
...
I want it to match each instance (i.e. 1st instance of both greps next two each other):
PopA_15.fq 1081264
PopA_16.fq 1008416
PopA_17.fq 554791
PopA_18.fq 604610
PopA_20.fq 531227
PopA_21.fq 595129
...
How do I do this? Thank you

Considering that your Input_file is same as sample shown and number of columns are even on each line with 1 PopA value and other will be with digit values. Following awk may help you in same.
awk '{for(i=1;i<=(NF/2);i++){print $i,$((NF/2)+i)}}' Input_file
Output will be as follows.
PopA_15.fq 1081264
PopA_16.fq 1008416
PopA_17.fq 554791
PopA_18.fq 604610
PopA_20.fq 531227
PopA_21.fq 595129
In case you want to pass output of a command to awk command then you could do like your command | awk command... no need to add Input_file to above awk command.

This is what ended up working for me...any tips for more efficient code are definitely welcome
#!/bin/bash
echo "Utilized reads from ustacks output" > reads.txt
str1="utilized reads:"
str2="Parsing"
for file in /home/desaixmg/novogene/stacks/sample01/conda_ustacks.o*; do
reads=$(grep $str1 $file | cut -d ':' -f 3)
samples=$(grep $str2 $file | cut -d '/' -f 8)
paste <(echo "$samples" | column -t) <(echo "$reads" | column -t) >> reads.txt
done
This provides the desired output described above.

sed '/[0-9]/d' file
If you want to edit your file "in place" use sed's option -i.
awk '!/[0-9]/' file
With bash:
while read -r line; do [[ ! $line =~ [0-9] ]] && printf "%s\n" "$line"; done < file

Just remove the start of the line anchor ^.
^[1-9] regex only matches the numbers 1-9 which exists at the start.
grep -v '[1-9]' Test.txt > 1_Test.txt
to work for all digits including 0.
grep -v '[0-9]' Test.txt > 1_Test.txt

A solution in AWK!
awk '!/[0-9]+/{print}' file

extract string from another using awk

I have this variable which contain a list of string separted by space
val=00:21:5D:16:F3 00:21:5D:16:F4 00:21:5D:16:F5
I want to extract each string separated bu space " " and then assign it to val
I use this shell code but it doesn't work
while [ "$((i++))" != "10" ]; do
val$i=`echo $val | awk '{print $i}'`
echo "val$i=$val$i"
done
the desired result is :
val1="00:21:5D:16:F3"
val2="00:21:5D:16:F4"
val3="00:21:5D:16:F5"
val4=""
val5=""
val6=""
val7=""
val8=""
val9=""
val10=""
any help is appreciated even if the treatment is done with another linux utility like cut , sed , grep.

this awk script should be what are you looking for

thank you for your help and I want to share with you the best solution that I found
while [ "$((i++))" != "10" ]; do
val$i=`echo $val | awk -F' ' '{print $'"$i"'}'`
echo "val$i=$val$i"
done

I Know is not what you really asked, but what about using array to solve this?
like:
val=(00:21:5D:16:F3 00:21:5D:16:F4 00:21:5D:16:F5)
$ echo ${val[0]}
00:21:5D:16:F3
$ echo ${val[1]}
00:21:5D:16:F4
$ echo ${val[2]}
00:21:5D:16:F5
$ echo ${val[3]}

Convert data from a simple JSON format to a DSV format

I have a file in Unix, with data sample like the following:
{"ID":"123", "Region":"Asia", "Location":"India"}
{"ID":"234", "Region":"APAC", "Location":"Australia"}
{"ID":"345", "Region":"Americas", "Location":"Mexio"}
{"ID":"456", "Region":"Americas", "Location":"Canada"}
{"ID":"567", "Region":"APAC", "Location":"Japan"}
The desired output is
ID|Region|Location
123|Asia|India
234|APAC|Australia
345|Americas|Mexico
456|Americas|Canada
567|APAC|Japan
I tried with a few sed commands. I could remove the following: '{', '}', ' " ', ':'
There are 2 issues with the output file
All rows from input appear in single line in the output.
Adding the pipe ('|') as delimiter.
Any pointers are highly appreciated.

I recommend the tool jq (http://stedolan.github.io/jq/); jq is a lightweight and flexible command-line JSON processor.
jq -r '"\(.ID)|\(.Region)|\(.Location)"' < infile
123|Asia|India
234|APAC|Australia
345|Americas|Mexio
456|Americas|Canada
567|APAC|Japan
Explanation
-r is --raw-output

Through awk,
awk -F'"' -v OFS="|" 'BEGIN{print "ID|Region|Location"}{print $4,$8,$12}' file
Example:
$ cat file
{"ID":"123", "Region":"Asia", "Location":"India"}
{"ID":"234", "Region":"APAC", "Location":"Australia"}
{"ID":"345", "Region":"Americas", "Location":"Mexio"}
{"ID":"456", "Region":"Americas", "Location":"Canada"}
{"ID":"567", "Region":"APAC", "Location":"Japan"}
$ awk -F'"' -v OFS="|" 'BEGIN{print "ID|Region|Location"}{print $4,$8,$12}' file
ID|Region|Location
123|Asia|India
234|APAC|Australia
345|Americas|Mexio
456|Americas|Canada
567|APAC|Japan
EXplanation:
-F'"' Sets " as Field Separator value.
OFS="|" Sets | as Output Field Separator value.
Atfirst, awk would execute the function inside the BEGIN block. It helps to print the header section.

This sed one-liner does what you want. It's capturing the field values using parenthesized expressions, and then putting them into the output using \1, \2, and \3.
s/^{"ID":"\([^"]*\)", "Region":"\([^"]*\)", "Location":"\([^"]*\)"}$/\1|\2|\3/
Invoke it like:
$ sed -f one-liner.sed input.txt
Or you can invoke it within a Bash script, producing the header:
echo 'ID|Region|Location'
sed -e 's/^{"ID":"\([^"]*\)", "Region":"\([^"]*\)", "Location":"\([^"]*\)"}$/\1|\2|\3/' $input

It is a JSON file so it is best to use a JSON parser. Here is a perl implementation of it.
#!/usr/bin/perl
use strict;
use warnings;
use JSON;
open my $fh, '<', 'path/to/your/file';
#keys of your structure
my #key = qw(ID Region Location);
print join ("|", #key), "\n";
#iterate over your file, decode it and print in order of your key structure
while (my $json = <$fh>) {
my $text = decode_json($json);
print join ("|", map { $$text{$_} } #key ),"\n";
}
Output:
ID|Region|Location
123|Asia|India
234|APAC|Australia
345|Americas|Mexio
456|Americas|Canada
567|APAC|Japan

Using sed as follows
Command line
echo "my_string" |
sed -e 's#[,:"{}]##g' -e 's#ID##g' -e "s#Region##g" -e 's#Location##g' \
-e '1 s#^.*$#ID Region Location\n&#' -e 's# #|#g'
or
sed -e 's#[,:"{}]##g' -e 's#ID##g' -e "s#Region##g" -e 's#Location##g' \
-e '1 s#^.*$#ID Region Location\n&#' -e 's# #|#g' my_file
I tried this in a terminal as follows:
echo '{"ID":"123", "Region":"Asia", "Location":"India"}
{"ID":"234", "Region":"APAC", "Location":"Australia"}
{"ID":"345", "Region":"Americas", "Location":"Mexio"}
{"ID":"456", "Region":"Americas", "Location":"Canada"}
{"ID":"567", "Region":"APAC", "Location":"Japan"}' |
sed -e 's#[,:"{}]##g' -e 's#ID##g' -e "s#Region##g" -e 's#Location##g' \
-e '1 s#^.*$#ID Region Location\n&#' -e 's# #|#g'
Output
ID|Region|Location
123|Asia|India
234|APAC|Australia
345|Americas|Mexio
456|Americas|Canada
567|APAC|Japan

Many thanks for your response and the pointers/ solutions did help a lot.
For some mysterious reasons, I couldn't get any sed commands work. So, I devised my own solution. Although it's not elegant, it's still worked.
Here is the script I prepared which resolved the issue.
#!/bin/bash
# ource file path.
infile=/home/exfile.txt
# remove if these temp file exist already.
rm ./efile.txt ./xfile.txt ./yfile.txt ./zfile.txt
# removing the curly braces from input file.
cat exfile.txt | cut -d "{" -f2 | cut -d "}" -f1 >> ./efile.txt
# setting input file name to different value.
infile=./efile.txt
# remove double quotes from the file.
while IFS= read -r line
do
echo $line | sed 's/\"//g' >> ./xfile.txt
done < "$infile"
# creating another temp file.
infile2=./xfile.txt
# remove colon from file.
while IFS= read -r line
do
echo $line | sed 's/\:/,/g' >> ./yfile.txt
done < "$infile2"
# set input file path to new temp file.
infile3=yfile.txt
# initialize variables to hold header column values.
t1=0
t3=0
t5=0
# read each of the line to extract header row. Exit loop after reading 1st row.
once=1
while IFS=',' read -r f1 f2 f3 f4 f5 f6
do
"$f1 $f2 $f3 $f4 $f5 $f6"
t1=$f1
t3=$f3
t5=$f5
if [ "$once" -eq 1 ]; then
break
fi
done < "$infile3"
# Read each of the line from input file. Write only the value to another output file.
while IFS=',' read -r f1 f2 f3 f4 f5 f6
do
echo "$f2|$f4|$f6" >> ./zfile.txt
done < "$infile3"
# insert the header column row into the file generated in the step above.
frstline="$t1|$t3|$t5"
sed -i '1i ID|Region|Location' ./zfile.txt
