Can't find the Linux command? (Command not found)

The problem is very simple, if you enter a command at the terminal and the system prompts you to say that the command did not find it, either because you did not install the appropriate package or because of a problem with the path setting. If it is because of the package problem, there is nothing else to say, install the corresponding package is good. In another case, the user's path needs to be set.

-bash:ls:command not found or-bash:ll:command not found
Cause: When setting environment variables, the edit profile is not correctly written, resulting in commands such as LS that are not recognized at the command line.

Export Path=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

Bash:php:command not found
Export path= $PATH:/usr/local/php/bin
Then, Echo $PATH look, and see.
At this time, you can directly in any directory of the system typing Php-i can be executed.

-bash:unzip:command not found
