解决 Debian 11 终端命令、文件、目录没有颜色问题

修改 ~/.bashrc 文件

nano ~/.bashrc

或者

vim ~/.bashrc

去掉以下几行命令的注释

# 这个选项告诉 ls 命令在显示文件和目录时，根据文件类型和属性来自动选择颜色。
export LS_OPTIONS='--color=auto' 
# 定义文件类型和属性与颜色的对应关系
eval "$(dircolors)" 
alias ls='ls $LS_OPTIONS'
alias ll='ls $LS_OPTIONS -l'
alias l='ls $LS_OPTIONS -lA'

修改后文件

# ~/.bashrc: executed by bash(1) for non-login shells.

# Note: PS1 and umask are already set in /etc/profile. You should not
# need this unless you want different defaults for root.
# PS1='${debian_chroot:+($debian_chroot)}h:w$ '
# umask 022

# You may uncomment the following lines if you want `ls' to be colorized:
export LS_OPTIONS='--color=auto'
eval "$(dircolors)"
alias ls='ls $LS_OPTIONS'
alias ll='ls $LS_OPTIONS -l'
alias l='ls $LS_OPTIONS -lA'
#
# Some more alias to avoid making mistakes:
# alias rm='rm -i'
# alias cp='cp -i'
# alias mv='mv -i'

使修改生效

source  ~/.bashrc
