 +

tcsh's builtin command <code>ls-F</code>, when invoked ''without other options'' while the shell variable <code>color</code> is set, colorizes the plain output of <code>/bin/ls -F</code>. tcsh uses the LS_COLORS environment variable to customize these colors. LS_COLORS uses the same format as expected by GNU <code>ls</code>. On a Linux system you can run <code>dircolors</code> to generate LS_COLORS from a config file, or run <code>dircolors --print-database</code> to see the config file. On FreeBSD, you can accomplish pretty much the same thing using the technique below.
 +
 +
However, if you invoke <code>/bin/ls</code> directly, or if you use <code>ls-F</code> ''with'' other options (like <code>ls-F -A</code>), then LS_COLORS is ignored. Instead, depending on whether the <code>color</code> shell variable is set, tcsh just passes the extra <code>ls-F</code> options to <code>/bin/ls</code> or <code>/bin/ls -G</code> (or <code>/bin/ls --color=auto</code> on non-BSD OSes). FreeBSD's <code>/bin/ls</code> uses an LSCOLORS environment variable (no underscore in its name) when colorizing the output. LSCOLORS has a special format and is much less capable than LS_COLORS; see the ls(1) man page. This colorization by <code>/bin/ls</code> will happen whenever it is invoked with <code>-G </code> ''or'' when the CLICOLOR environment variable is set. However, it will not happen if the output is being redirected and CLICOLOR_FORCE is not set. Apps which parse the output of <code>/bin/ls</code> tend to have difficulty when CLICOLOR_FORCE is set.
 +
 +
I made the following changes from the [https://forums.freebsd.org/threads/howto-color-files-by-extension-in-tcsh.29669/ original version]:
 +
* made the defaults match my LSCOLORS
 +
* added a few document, media, and source file types
 +
* changed the heinous purple document color to bright white
 +
* changed <code>Makefile</code> to <code>*Makefile</code>, for compatibility with GNU 'ls'
 +
* added comments about the portability of the <code>mi</code> and <code>or</code> codes

 +
 +
# SYNOPSIS:  an enhancement  of  the tcsh  builtin  'LS_COLORS' providing  a
 +
# method of  organizing/externalizing file  colors. The  strategy is  to use
 +
# only native FreeBSD components (no 3rd party pkgs or ports).
 +
 +
# REQUIREMENTS: tcsh, awk, & your favorite editor
 +
 +

# SETUP (3 steps):

#
 +
# if (-f ~/.colors) then

#    set listflags='ha'

#    set color
 +
#    setenv LS_COLORS `awk '! /^#|^$|\t/ {printf $1"="$2":"}' ~/.colors`
 +
# endif
 +
#
 +
# 3. (re)source your ~/.tcshrc by invoking 'source ~/.tcshrc'

Here are the tcsh shell configuration files I use. I try to keep them compatible with csh but have not fully tested them there.

Any questions/comments/suggestions, email me directly at root (at) skew.org.

.colors

This is referenced by my .cshrc, above.

tcsh's builtin command ls-F, when invoked without other options while the shell variable color is set, colorizes the plain output of /bin/ls -F. tcsh uses the LS_COLORS environment variable to customize these colors. LS_COLORS uses the same format as expected by GNU ls. On a Linux system you can run dircolors to generate LS_COLORS from a config file, or run dircolors --print-database to see the config file. On FreeBSD, you can accomplish pretty much the same thing using the technique below.

However, if you invoke /bin/ls directly, or if you use ls-F with other options (like ls-F -A), then LS_COLORS is ignored. Instead, depending on whether the color shell variable is set, tcsh just passes the extra ls-F options to /bin/ls or /bin/ls -G (or /bin/ls --color=auto on non-BSD OSes). FreeBSD's /bin/ls uses an LSCOLORS environment variable (no underscore in its name) when colorizing the output. LSCOLORS has a special format and is much less capable than LS_COLORS; see the ls(1) man page. This colorization by /bin/ls will happen whenever it is invoked with -G or when the CLICOLOR environment variable is set. However, it will not happen if the output is being redirected and CLICOLOR_FORCE is not set. Apps which parse the output of /bin/ls tend to have difficulty when CLICOLOR_FORCE is set.

I made the following changes from the original version:

  • made the defaults match my LSCOLORS
  • added a few document, media, and source file types
  • changed the heinous purple document color to bright white
  • changed Makefile to *Makefile, for compatibility with GNU 'ls'
  • added comments about the portability of the mi and or codes
# ~/.colors v0.99 for FreeBSD tcsh - [c]2012 Michael S. Sanders

# SYNOPSIS:  an enhancement  of  the tcsh  builtin  'LS_COLORS' providing  a
# method of  organizing/externalizing file  colors. The  strategy is  to use
# only native FreeBSD components (no 3rd party pkgs or ports).

# SETUP (3 steps):
#
# 1. save this file in your home directory as '.colors'
#
# 2. add the following construct to ~/.tcshrc, or ~/.cshrc (excluding '#')
#
# if (-f ~/.colors) then
#    alias ls 'ls-F'
#    set listflags='ha'
#    set color
#    setenv LS_COLORS `awk '! /^#|^$|\t/ {printf $1"="$2":"}' ~/.colors`
# endif
#
# 3. (re)source your ~/.tcshrc by invoking 'source ~/.tcshrc'
