Hi Birai,

I am getting output as same as input.
Code:
cat infile
1|2|3|a02 test|303
2|2|4|1002 a05 ind|303
4|3|5|ind|30

awk 'BEGIN { FS = OFS = "|" } { num_words = split( $4, words, /\s+/ ); if ( num_words > 2 ) { sub( /\S+\s/, "", $4 ) } gsub( /\s+/, "", $4 ); print }' infile
1|2|3|a02 tet|303
2|2|4|1002 a05 ind|303
4|3|5|ind|30

Hi SK1418,

Getting error message:
Code:
awk -F'|' -v OFS='|' '{$4=gensub(/.* (.*) (.*)$/,"\\1\\2","g",$4);gsub(/ /,"",$4)}1' infile
awk: Function gensub is not defined.
 The input line number is 1. The file is infile.
 The source line number is 1.

i am using HP-UX.

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
