1 在Linux环境下找不到ll命令
在 ~/.bashrc文件中添加
# .bashrc
# User specific aliases and functions
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
#定义ll命令
alias ll='ls -l'
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
2 ll时间格式化
Linux默认时间格式，查看不够直观。例如
drwx------ 2 nobody root 6 Jan 28 2022 client_body_temp
drwxr-xr-x 3 root root 4096 Sep 15 14:15 conf
drwx------ 2 nobody root 6 Sep 10 2019 fastcgi_temp
drwxr-xr-x 29 root root 8192 Jun 15 2022 html
drwxr-xr-x 2 root root 6 Nov 8 08:29 logs
drwx------ 3 root root 15 Jul 27 11:15 proxy_cache
drwx------ 12 nobody root 96 Sep 10 2019 proxy_temp
drwxr-xr-x 2 root root 19 Sep 10 2019 sbin
drwx------ 2 nobody root 6 Sep 10 2019 scgi_temp
drwxr-xr-x 3 root root 80 Jun 9 2020 ssl
drwx------ 2 nobody root 6 Sep 10 2019 uwsgi_temp
ll --time-style="+%Y-%m-%d %H:%M:%S"

drwx------ 2 nobody root 6 2019-09-10 14:22:29 uwsgi_temp
将配置添加的环境变量中
echo "export TIME-STYLE='+%Y-%m-%d %H:%M:%S'" >> ~/.bashrc
