Printing file names with grep by default when grep receives nfiles>1 may produce output with and without file names (when called via find). * Edit the attached shell script: (Set the var 'dir' with the location of the local grep repository). * Run the script. * Read the comments inside the script and check the output. ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Subject: [PATCH] Do not print file names by default when nfiles >1
* src/grep.c (main): Print file names only when command contains
the option --with-filename (or -H).
* doc/grep.texi (-H, --with-filename): Update documenation.
