Join 2 separate strings into one with alternate tokens.


I have two strings eg:

I want a new string with
string3="abc:12 def:13 hij:14"

I am using shell scripting. Is there any method to do this?

I tried using cut command but this wont advance the respective strings.
Can anybody help in this matter?

Not a pure shell solution, however the following works
export string1="abc|def|hij"
export string2="12|13|14"
string3=$(perl -e '@f=split /\|/, $ENV{string1};@s=split /\|/, $ENV{string2};for (0..$#f){print "$f[$_]:$s[$_] "}')
echo $string3

It runs from the command line, but not from the script file.
Any idea?

I am running this script as

a pure shell (ksh) solution :



set -A str1 ${string1}
set -A str2 ${string2}


(( cnt1 > cnt2 )) && cnt=${cnt1} || cnt=${cnt2}

while (( cnt > 0 ))
   (( cnt -= 1 ))
   string3="${str1[$cnt]}:${str2[$cnt]} ${string3}"

string3="${string3# }"
print "${string3}"

It worked fine in ksh. Thanks for the help.
But it gives wrong results for strings of different length.
Any idea to restrict it to the smaller string among the both?

str3=$(echo "$str1 $str2" | sed 's/\(.*\)|\(.*\)|\(.*\) \(.*\)|\(.*\)|\(.*\)/\1:\4 \2:\5 \3:\6/')
