Full Discussion: Print the grepped string alongwith the filename
Top Forums UNIX for Dummies Questions & Answers Print the grepped string alongwith the filename Post 302767841 by RudiC on Thursday 7th of February 2013 02:54:28 PM

Well, not sure where to start... why do you echo -n the grep command? Use on its own and redirect to your output file. Why use echo -n at all? Do you need all output in one single line?

Using the correct options to grep will seriously help:
Code:
-E use extended regexes
-i ignore char case
-r scan directories recursively
-o print matched string

So, if I run
Code:
$ dir=.
$ line="ABC|awk"              # extended regex: match ABC -OR- awk; with -i: either case
$ grep -Eior $line $dir

it will happily output
Code:
./awk/tranposehugefile:ABC
./awk/separateHtmlMail:abc
./awk/tranposehugefile:awk
./awk/merge2:awk
.
.
.
./awk/lowertriangmatrix:awk
./safe/solutions~:awk

which I guess is what you want (don't know if you need regexes; remove if need be) . Of course you're free to replace the : by | with e.g. sed...

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
