The latest one works in the command line but not in the script.
Code:
echo "$string1 $string2"  | tr ' |' '\n\n' | pr -2 -t -s: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/' | xargs

the following one works in scripts, for now I am using this one itself.
Code:
paste -d: <((echo $string2 | sed 's/\|/ /g' | xargs -n1) | cut -f1 -d:) <(echo $string1 |
 sed 's/\|/ /g' | xargs -n1)  <((echo $string2 | sed 's/\|/ /g' | xargs -n1) | cut -f2 -d: ) | xargs

Is there any method to incorporate the first one into the script file?

I have new question:

I have a string:

s1="123:1,124:2,126:4"

I want

s2="123 124 126"

What should I use?

---

Got it:

Code:
$echo $s1 | tr ',' '\n' | cut -f1 -d: | xargs
123 124 126

Could you please explain the purpose of $ENV (in this context).
is ENV variable used to pull the environment variables (declared in the shell) into the script?
If that is the case ...the following didn't work...could you please correct it.
Code:
#!/bin/ksh
# this script is used to concatenate 2 strings after removing the delimiter
string1="abc|def|hij"; echo $string1;
string2="12|13|14"; echo $string2;
string3=$(perl -e '@f=split( /\|/, $string1);@s=split(/\|/, $string2);for (0..$#f){print "$f[$_]:$s[$_] "}')
echo $string3

thanks,
perl rookie

@Sikku :
Code:
$echo $s1 | tr ',' '\n' | cut -f1 -d: | xargs
123 124 126

could be shorten (and save some pipe as well) with:
Code:
echo $s1 | sed 's/:[^,]*//g;s/,/ /g'

Code:
echo "$string1 $string2" | tr ' |' '\n\n' | pr -2 -t -s: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/' | xargs

Works in command line but does not work in your script ???
Could you please show the content of your script, it sounds weird that you could not pass that command from within your script .

@ctsgnb:

This is the content of my script

Code:
#!/bin/ksh

string1="abc|def|hij"
string2="123:1|134:2|145:3"

#string3="`paste -d: <((echo $string2 | sed 's/\|/ /g' | xargs -n1) | cut -f1 -d:) <(echo $string1 | \
#         sed 's/\|/ /g' | xargs -n1)  <((echo $string2 | sed 's/\|/ /g' | xargs -n1) | cut -f2 -d: ) | xargs`"

string3="`echo "$string1 $string2" | tr ' |' '\n\n' | pr -2 -t -s: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/' | xargs`"
echo $string3

I get this error: (list is the script name)
Code:
$ list
./list[9]: : cannot execute
./list[9]: 123:1|134:2|145:3 | tr ' |' '\n\n' | pr -2 -t -s: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/' | xargs: cannot execute

Try this :
Code:
string3=$(echo "$string1 $string2" | tr ' |' '\n\n' | pr -2 -t -s: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/' | xargs )
echo $string3

In fact my script should be like this:

Code:
#!/bin/ksh

string1="abc|def|hij"
string2="1212|2134|1245"
string3="123:1|134:2|145:3"

string4="`paste -d: <(echo $string1 | sed 's/\|/ /g' | xargs -n1) <(echo $string2 | sed 's/\|/ /g' | xargs -n1) | xargs`"

#string4="$string3 `paste -d: <((echo $string3 | sed 's/\|/ /g' | xargs -n1) | cut -f1 -d:) <(echo $string1 | \
#         sed 's/\|/ /g' | xargs -n1)  <((echo $string2 | sed 's/\|/ /g' | xargs -n1) | cut -f2 -d: ) | xargs`"

string4="$string4 `echo "$string1 $string3" | tr ' |' '\n\n' | pr -2 -t -s: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/' | xargs`"
echo $string3

I want to add string3 to string4 and then append the last result to string4 again.
