Hi,
Thanks a lot for the valuable help..

The command that you gave last worked fine, but then the issue am facing now is i need to print some values before the execution of script.

This is what actually am trying for :

Code:
awk -F"|" '{print $1,$2,$3,system("echo" $4),$5,$6,system("convert.sh" $12 $13 $9 $10)}' input_file

when i was trying this command i was facing the issue with the exit status.

But then the command you provided replaced the system , but then i am not able to get the previous values printed.

Please advise..

Hi,
To make it more precise :

The input file content:

file name : input_file

Code:
2012                 | TEST | TEST1   |              14031 |      276500 |  TST2               |  334FAAA     |       124706 |       274506 |      2142767 |       346329 |  x'55'         |  x'4F'                 |            0 |       40 |        0

Code tried :

Code :

Code:
awk -F"|" '{print $1,$2,$3,system("echo" $4),$5,$6,system("convert.sh" $12 $13 $9 $10)}' input_file


Expected output :

Code:
2012 TEST TEST1 14031 276500 TST2 2012 TEST TEST1 14031 276500 TST2 v7126-6528-6230-6530-YOA1-274506-85-79-2142767

the last value v7126-6528-6230-6530-YOA1-274506-85-79-2142767 is the output from the convert.sh.

But the output that i currently get is :

Code:
2012 TEST TEST1 14031 
0 276500 TST2 v7126-6528-6230-6530-YOA1-274506-85-79-2142767
0

Thanks !

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
