linux添加ll命令,CENTOS: Docker的容器系统加上ll命令

Docker的很多Image都少量一些我们平时用的命令，ll就是其中一个。其实ll是一个alias来的。

只要修改 ~/.bashrc就可以。

运行以下命令

nano ~/.bashrc

内容大概如下：

# ~/.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'

把这一行：# alias ll='ls $LS_OPTIONS -l'的#号去掉，然后存盘。

现在你可以用ll了。
