Linux 中的彩色控制台输出

--color例如，许多 GNU 软件中都有一个选项ls。因此我希望具有此选项 ( --color auto) 的程序默认使用它，即使它没有写出来。

我使用的 Arch Linux 和 Live CD 控制台有彩色输出，但是安装的一个还没有。

答案1

您可以创建一个别名对于这些命令，以便这些命令总是使用这些选项。

例如

alias ls='ls --color auto'

现在每次使用时ls它都会扩展为ls --color auto。

别名是 shell 的内置命令，因此语法可能因 shell 的不同而有所差异。

只需将这些别名放入启动 shell 时执行的其中一个文件中即可。

答案2

您可以使用可爱的 Linux Mint .bashrc 文件。

进入您的主文件夹，将您的实际 .bashrc 文件复制到 .bashrc_backup 并创建一个包含以下内容的新 .bashrc：

# System-wide .bashrc file for interactive bash(1) shells.

# To enable the settings / commands in this file for login shells as well,
# this file has to be sourced in /etc/profile.

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then
    debian_chroot=$(cat /etc/debian_chroot)
fi

alias ll='ls -al'

use_color=true

# Set colorful PS1 only on colorful terminals.
# dircolors --print-database uses its own built-in database
# instead of using /etc/DIR_COLORS.  Try to use the external file
# first to take advantage of user additions.  Use internal bash
# globbing instead of external grep binary.
safe_term=${TERM//[^[:alnum:]]/?}   # sanitize TERM
match_lhs=""
[[ -f ~/.dir_colors   ]] && match_lhs="${match_lhs}$(<~/.dir_colors)"
[[ -f /etc/DIR_COLORS ]] && match_lhs="${match_lhs}$(</etc/DIR_COLORS)"
[[ -z ${match_lhs}    ]] \
        && type -P dircolors >/dev/null \
        && match_lhs=$(dircolors --print-database)
[[ $'\n'${match_lhs} == *$'\n'"TERM "${safe_term}* ]] && use_color=true

if ${use_color} ; then
        # Enable colors for ls, etc.  Prefer ~/.dir_colors #64489
        if type -P dircolors >/dev/null ; then
                if [[ -f ~/.dir_colors ]] ; then
                        eval $(dircolors -b ~/.dir_colors)
                elif [[ -f /etc/DIR_COLORS ]] ; then
                        eval $(dircolors -b /etc/DIR_COLORS)
        else

        fi

        alias ls='ls --color=auto'
        alias grep='grep --colour=auto'

        if [[ ${EUID} == 0 ]] ; then
