关于ls命令颜色问题！
寒江兄可真是多面手。 其实我是不用这些东西的， 只是回答问题而已。
很多从 Windows 及 Linux 转过来的人，动不动就要 GUI. 比如这位
就要 color. UNIX 的纯洁度越来越差了。
索性好人做到底。
Coloured ls output in 10 steps
Always dreamt of having the same sort of output on your Solaris machine as you would have on Linux? Here is how you go at that.
1. Coloured output is a feature of the GNU version of ls. So you first have to obtain this version. GNU ls is in the coreutils package. You can download it from (a mirror) of sunfreeware.com.
2. Install the package using the pkgadd command:
root@host /var/tmp>; pkgadd -d coreutils-4.5.4-sol9-sparc-local
The following packages are available:
1 SMCcoreu coreutils
(sparc) 4.5.4
Select package(s) you wish to process (or 'all' to process
all packages). (default: all) [?,??,q]: y
--output ommitted--
3. This will install GNU ls and some other useful GNU programs in /usr/local/bin. Check this directory.
4. Information about the commands can be found in /usr/local/doc and /usr/local/man. Read the documentation for the new commands, e.g. for dircolors:
user@host ~>; man -M /usr/local/man dircolors
Lateron, make sure that the MANPATH variable includes /usr/local/man.
5. Colours can also be set system wide, in that case you need a DIR_COLORS file in /etc. It may look somewhat like this:
user@host ~>; cat /etc/DIR_COLORS
# Configuration file for the color ls utility
# This file goes in the /etc directory, and must be world readable.
# You can copy this file to .dir_colors in your $HOME directory to override
# the system defaults.
# COLOR needs one of these arguments: 'tty' colorizes output to ttys, but not
# pipes. 'all' adds color characters to all output. 'none' shuts colorization
# off.
COLOR tty
# Extra command line options for ls go here.
# Basically these ones are:
# -F = show '/' for dirs, '*' for executables, etc.
# -T 0 = don't trust tab spacing when formatting ls output.
OPTIONS -F -T 0
# Below, there should be one TERM entry for each termtype that is colorizable
TERM linux
TERM console
TERM con132x25
TERM con132x30
TERM con132x43
TERM con132x60

# Below are the color init strings for the basic file types. A color init
# string consists of one or more of the following numeric codes:

# Text color codes:
# 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white
# Background color codes:
# 40=black 41=red 42=green 43=yellow 44=blue 45=magenta 46=cyan 47=white

6. Test that your new setup works, using the /usr/local/bin/ls --color command in a couple of directories.
If your colours seem ok (look also at other than plain text files), proceed to the next step.
7. Now we don't want to type /usr/local/bin/ls --color all the time. You can solve the problem by altering your PATH variable:
user@host ~>; export PATH=/usr/local/bin PATH
This way, when you just type ls, the first occurance in your search path will be the ls from /usr/local/bin instead of the default one from /usr/bin.
8. Now we already have the correct program when we call it, but we are lazier than that, because we don't want to type the --color option all the time either. So you might want to alias the ls command:
user@host ~>; alias ls='ls --color'
Mind that this does not work for the common shell, /sbin/sh. You need a more advanced shell for making aliases, such as bash or ksh.
9. Of course, when you log out, all these settings are gone, so add these lines to your shell configuration file, e.g. ~/.bashrc:
user@host ~>; echo 'export PATH=/usr/local/binPATH' >;>; ~/.bashrc
user@host ~>; echo "alias ls='ls --color'" >;>; ~/.bashrc
10. In order to make these settings available for all users on the system, put these last two lines in /etc/profile (check first, if PATH is already defined, it is cleaner to arrange the existing definition. |
