Concatenating two mutiline variables in a bash
Hi All,
I am having a situation where am capturing results in two variables from an xml file. However, I am looking to print those two variables with pipe in between them and these variable are multi-line.
This is how my 1st variable looks like:
Code:
20181225010
20190224010
20190224010
20190303010
20190304010
20190306010
20190319010
20190320010
20190321010

This is my 2nd variable
Code:
906676175
907339851
907453926
907453962
907687907
909465451
909587811
909276884
913772782

Expected output:
Code:
20181225010|906676175
20190224010|907339851
20190224010|907453926
20190303010|907453962
20190304010|907687907
20190306010|909465451
20190319010|909587811
20190320010|909276884
20190321010|913772782

Any assistance would be greatly appreciated.

Hello svks1985,

Could you please try following.
Code:
awk 'FNR==NR{a[FNR]=$0;next} {print a[FNR]"|"$0}' <(echo "$var1")  <(echo "$var2")

2nd solution: With paste.
Code:
paste -d'|' <(echo "$var1") <(echo "$var2")

Thanks,
R. Singh

Thanks much RavinderSingh13.
1st solution is printing the output like this
Code:
|20181225010
|20190224010
|20190224010
|20190303010
|20190304010
|20190306010
|20190319010
|20190320010
|20190321010
|858485461
|881854750
|881854752
|886257846
|887682847
|886981196
|894784176
|895564612
|894060226

However paste option is working just fine.

Try also
Code:
ARR1=( $VAR1 )
ARR2=( $VAR2 )
for IX in ${!ARR1[@]}; do echo "${ARR1[IX]}|${ARR2[IX]}"; done
20181225010|906676175
20190224010|907339851
20190224010|907453926
20190303010|907453962
20190304010|907687907
20190306010|909465451
20190319010|909587811
20190320010|909276884
20190321010|913772782


Be aware that RavinderSingh13's 2nd proposal requires a recent shell offering "process substitution".

Thanks RudiC
Your solution works just fine.
However, I would greatly appreciate if you can provide some explanation around it. To be specific, I am looking for

man bash:

for name [ [ in [ word ... ] ] ; ] do list ; done
The list of words following in is expanded, generating a list of items. The variable name is set to each element of this list in turn, and list is executed each time.

... It is possible to obtain the keys (indices) of an array as well as the values. ${!name[@]} and ${!name[*]} expand to the indices assigned in array variable name.
