Clarification: I do have GREP_OPTIONS=--color=auto in my environment (FreeBSD uses GNU grep). If you were printing matching lines, i.e. not using -v, and not redirecting the grep output, the matching text would be colored red. Obviously that's not applicable here. Anyway, I have more info for you. The output of these is the same: 'ls -ld /usr/.* | cat -vet' 'ls -ld /usr/.* | egrep -v '/\.\.?$' | cat -vet' Here it is: 2 drwxr-xr-x 22 root wheel 512B Aug 28 2013 ^[[1m^[[36m/usr/.^[[39;49m^[[m/$ 2 drwxr-xr-x 21 root wheel 1.0k Sep 3 17:29 ^[[1m^[[36m/usr/..^[[39;49m^[[m/$ 2 drwxrwxr-x 2 root operator 512B Aug 23 19:24 ^[[1m^[[36m/usr/.snap^[[39;49m^[[m/$ Now here's '/bin/ls -ld /usr/.* | egrep -v '/\.\.?$' | cat -vet': drwxr-xr-x 22 root wheel 512 Aug 28 2013 ^[[1m^[[36m/usr/.^[[39;49m^[[m$ drwxr-xr-x 21 root wheel 1024 Sep 3 17:29 ^[[1m^[[36m/usr/..^[[39;49m^[[m$ drwxrwxr-x 2 root operator 512 Aug 23 19:24 ^[[1m^[[36m/usr/.snap^[[39;49m^[[m$ Calling /bin/ls instead of my 'ls' alias, as you can see, results in some formatting changes due to the omission of -F: no trailing slashes on directories, 1st column is gone, BLOCKSIZE=1k environment variable ignored. The color is still there because I also have the environment variables CLICOLOR and CLICOLOR_FORCE set. The former is used by FreeBSD's /bin/ls to always output color, as if -G were set, and the latter is to ensure it happens even when piping the output (e.g. to 'less', as I do with another alias for long directory listings). As long as you pipe the output, unsetting CLICOLOR_FORCE stops the coloring: # unsetenv CLICOLOR_FORCE # /bin/ls -ld /usr/.* | egrep -v '/\.\.?$' | cat -vet drwxrwxr-x 2 root operator 512 Aug 23 19:24 /usr/.snap$ #/bin/ls -ld /usr/.* | cat -vet drwxr-xr-x 22 root wheel 512 Aug 28 2013 /usr/.$ drwxr-xr-x 21 root wheel 1024 Sep 3 17:29 /usr/..$ drwxrwxr-x 2 root operator 512 Aug 23 19:24 /usr/.snap$ Some experimentation shows that the only way to be sure color is suppressed is to temporarily unset CLICOLOR_FORCE, if not also CLICOLOR. Unlike GNU ls's --color=[auto,none], there's no command-line option for BSD's /bin/ls that can override the effect of those environment variables. (And unsetting the 'color' shell variable only suppresses the tcsh's coloring of 'ls-F' called without arguments, n/a here.) I hope this helps. ------------------------------------------------------------------------------ _______________________________________________ Rkhunter-users mailing list Rkhunter-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/rkhunter-users
