-bash: ll: 未找到命令

第一步将alias ll='ls -l'添加到/etc/profile

# head /etc/profile
# /etc/profile
alias ll='ls -l'
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.

第二步

# source /etc/profile

#ll

问题:常用命令“ll”失效,如图所示

"ll"命令不是linux的基本命令,它是"ls -l"的别名,部分版本并不直接支持“ll”命令输出。

解决方法:

运行“vi ~/.bashrc”,查看该文件里是否有“alias ll='ls -l'”这样的数据,如有,将数据前的“#”去掉,如果没有,将“alias ll='ls -l'”加进去并保存,然后运行“source ~/.bashrc”命令,即可成功。如下图:
