如何把命令加如路径

909

比如说把 “id”加入PATH中~要怎么做？？？

yangh

找到先找到 id 在哪儿

[code:1]root #> whereis id
id: /usr/bin/id /usr/include/id3.h /usr/share/man/man1/id.1.gz
[/code:1]

然后加到 ~/.bashrc 里
[code:1]
root #> cat /root/.bashrc
# ~/.bashrc: executed by bash(1) for non-login shells.

#set path enverement
PATH="$PATH:/usr/bin"
[/code:1]

其实这个路径默认已经有了的
