Filenames such as foo.exe or bar.bin:

It works.. Thank you so much

Code:

[@soctxadm01:~]$ grep .mml list_fi |wc -l

[@soctxadm01:~]$

[@soctxadm01:~]$  grep -Eo '[[:alnum:].-]+\.(mml)' list_fi|sort|uniq|wc -l
841

Code:

 grep -Eo '[[:alnum:].-]+\.(mml) - character per character..

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
