Hello,
Many thanks for your reply, i have test both of them
for this code,
Code:
awk -F"!" '{  printf("%-7s%-22s%-17s%-4s\n",$1,FNR,$2,$3,$4); }' input_file.txt

i got this error "bash: !: event not found"



this code is working fine

Code:
awk '{ if($2 !~ /^A/) { $3=$2; $2=""; } printf("%-7s%-22s%-17s%-4s\n",$1,FNR,$2,$3); }' filename

But dennis, second attribute can start with any character, A-Z and 0-9
so tried /^[A-Z]/ and ok , but when i write /^[A-Z][0-9]/ ,it is not working.

Any idea,




Many 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
