Linux 中的彩色控制台輸出

Linux 中的彩色控制台輸出

例如,--color許多 GNU 軟體都有一個選項。ls所以我希望具有此選項(--color auto)的程式預設使用它,即使它沒有寫入。

我使用 Arch Linux 和 Live CD 控制台有彩色輸出,但安裝了一個卻沒有。

答案1

你可以創建一個別名對於這些命令,以便這些命令始終使用這些選項。

例如

alias ls='ls --color auto'

現在每次你使用ls它都會擴展為ls --color auto.

別名是 shell 內建指令,因此語法可能會根據您的 shell 的不同而有所不同。

只需將這些別名放入啟動 shell 時執行的檔案之一即可。

您可以使用可愛的 Linux Mint .bashrc 檔案。

進入您的主資料夾,將實際的 .bashrc 檔案複製到 .bashrc_backup 並建立一個新的 .bashrc,其中包含:

# 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
            eval $(dircolors)

        alias ls='ls --color=auto'
        alias grep='grep --colour=auto'
else
        if [[ ${EUID} == 0 ]] ; then
