I took the color-ls patch from sunsite.unc.edu, and applied it to the ls from GNU fileutils 3.4. This patch, for those who are not familiar with it, provides colorization of ls output according to file permissions and type. From there, I made modifications to add the following features: -- Text attributes (normal, bold, flashing, etc.) are now supported. -- The program checks to see if output is to a tty, and automatically disables colorization if it is not. Any pipes that take input from ls will get normal, non-colorized input. -- Support has been added for colorization by filename extension. For instance, any filenames ending in ".tgz", ".taz", ".Z", ".z", ".zip", ".lzh", etc. will show up in bold red. Things still to do: -- It would be nice if this used the ls from fileutils 3.5, but the old patch wouldn't work with it and I didn't want to start from scratch. But someday... In the meantime, the source needed for this patch is the GNU fileutils version 3.4. I found it at nic.funet.fi. -- If I could figure out how to detect the filesystem type of the directory being listed, it would be nice to disable executable detection for MS-DOS partitions, since all files appear with -rwxr xr x permissions on those, and so they all wind up being colorized as executables. (Except where filename extensions are detected. Those will always take precedence.) Anyway, the new, improved patch follows. It's currently set up with the colors I like to use, but the internal documentation explains how to change them to whatever you like. I recommend compiling the program so that it defaults to color output. You can always use the "-f" flag to disable it. You'll have to add a couple flags to the DEFS statement in the Makefile to get it to work. I recommend using -DCOLOR=1 -DEIGHTBIT=1 Have fun! --- Patrick Volkerding volkerdi@mhd1.moorhead.msus.edu bf703@cleveland.freenet.edu *** ls.c~ Thu Oct 15 03:08:47 1992 --- ls.c Tue May 18 20:44:32 1993 *************** *** 32,37 **** --- 32,55 ---- /* Written by Richard Stallman and David MacKenzie. */ + /* 8-bit and color support by Peter Anvin + + Color support based on original patches by Greg Lee + + + Display attributes support, auto-disable for pipes, and colors according to + file suffixes added by Patrick Volkerding (volkerdi@mhd1.moorhead.msus.edu) + + These features are conditionalized.
