awk not working in script
Hi All,
i'm trying awk commnad to read only file names with the help of below command :-
ls -l tmp*.txt | awk { 'print $9' } | head -1
The command is working fine
on command line, but when i trying it in script then its not working
$var1=`ls -l tmp*.txt | awk { 'print $9' } | head -1`
print "$var1 \n";
the o/p of $var1 is only for ls -l tmp*.txt and not for others
Please advise me if i'm doing it wrong.
Thanks in Adv

I manned awk and it was very confusing. I viewed previous posts on this board and I got the same results as with the
the awk command statement shown here. Please help.

IGAWK(1) Utility Commands IGAWK(1) 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
