@ctsgnb Thanks.

Your code also worked.
I have small change in the string2 and want the output in a different way now


the format is like this
string2=<1234>:<1 to 24>|<1235>:<1 to 24>

Rule is to have same no of tokens in both the strings, but it may vary depending upon who inputs the values.
Need to have check before itself.

I want the output as follows:
string3="123:abc:2 124:def:1 125:ghi:3"

I know its bit complicated, but provided the way you people have given replies it seems to be very easy for you.

I am very weak in scripting, but my boss has given me some work on this and I need to deliver it soon...

Appreciate if you can help.

Thanks for the pr command. And we can shorten your latest post using tr or sed Smilie
echo $string1 $string2| sed 's/[ |]/\n/g'| pr -2 -t -s: | xargs

For me it works better with tr :

[ctsgnb@shell ~/sand]$ echo "$string1 $string2" | sed -e "s/[ |]/\n/g" | pr -2ts: | xargs
[ctsgnb@shell ~/sand]$ echo "$string1 $string2" | tr ' |' '\n' | pr -2ts: | xargs
abc:12 def:13 hij:14

@sikku :

[ctsgnb@shell ~/sand]$ echo "$string1 $string2"  | tr ' |' '\n' | pr -2ts: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/' | xargs
123:abc:2 124:def:1 125:ghi:3

Dint work for me. Smilie
Maybe I am using sun OS?

$ echo $string1
$ echo $string2
$ echo "$string1 $string2"  | tr ' |' '\n' | pr -2ts: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/' | xargs

I tried with this:
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
123:abc:1 124:def:2 125:hij:3

Is there any possibility to reduce the code?

@sikku, try again separating the option of pr command, and make sure you didn't forget anything in the sed syntax.

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

then you can pass the statement step by step to see what doesn't behave as expected :

See how the final output is built step by step :

[ctsgnb@shell ~/sand]$ echo "$string1 $string2"
abc|def|ghi 123:2|124:1|125:3
[ctsgnb@shell ~/sand]$ echo "$string1 $string2"  | tr ' |' '\n'
[ctsgnb@shell ~/sand]$ echo "$string1 $string2"  | tr ' |' '\n' | pr -2 -t -s:
[ctsgnb@shell ~/sand]$ echo "$string1 $string2"  | tr ' |' '\n' | pr -2 -t -s: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/'
[ctsgnb@shell ~/sand]$ echo "$string1 $string2"  | tr ' |' '\n' | pr -2 -t -s: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/' | xargs
123:abc:2 124:def:1 125:ghi:3
[ctsgnb@shell ~/sand]$

I told you, it behaves in a different way.

$  echo "$string1 $string2"
abc|def|hij 123:2|124:1|125:3

$  echo "$string1 $string2"  | tr ' |' '\n'

$  echo "$string1 $string2"  | tr ' |' '\n'  | pr -2 -t -s:

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

---------- Post updated at 07:30 AM ---------- Previous update was at 07:26 AM ----------

Check this output:
$ echo "$string1 $string2"  | tr '|' '\n'
hij 123:2

---------- Post updated at 07:35 AM ---------- Previous update was at 07:30 AM ----------

Look at this now:
$ echo "$string1 $string2"  | tr '|' '\n' | tr ' ' '\n'

lol.. I have no idea how its happening?

now the full command works:
$ echo "$string1 $string2"  | tr '|' '\n' | tr ' ' '\n' | pr -2 -t -s: | sed 's/^\([^:]*\):\([^:]*\)/\2:\1/' | xargs
123:abc:2 124:def:1 125:hij:3

Merge the two tr statement into one :
echo "$string1 $string2"  | tr ' |' '\n\n'
