Linux command fail

Problem Description

Command in Centos undefined after I updated environment variable. Including install command like vimvilsllsudosystemctl.

Solution

  1. Use command below can fix the problem temporary, but export command only valid on current ssh link. It breaks after close the window.
    export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
  2. Edit or delete the wrong config added in /etc/profile by vim /etc/profile or edit file ~/.bash_profile by vim ~/.bash_profile
  3. Activate the config by execute source /etc/profile or source ~/.bash_profile
