Solution to Linux not supporting all commands

What should I do if Linux does not support all commands? Solve the problem that all Linux commands cannot be used

This problem indicates that there is a problem with your /etc/profile configuration, usually because there is a problem with the path configuration. Eliminate the errors in the added content, then restart a new window and execute source /etc/profile to solve the problem.

When all commands are disabled, vi becomes useless.

At this time, you need to use the absolute path of the shell command to call the command.

# Edit the profile file /usr/bin/vim /etc/profile

Then execute in a new window

source /etc/profile

All linux commands cannot be used

When configuring nginx, all linux commands cannot be used after the error export

This problem occurs because the system's environment variables are not configured correctly. There are many reasons for this, such as system upgrades, improper operations, etc., which cause the environment variables to be overwritten and modified. There are two ways to solve it.

First: Enter the following directly in the Linux command line interface and press Enter (import environment variables and the storage address of common shell commands):

export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

Second: If all system commands cannot be used, you can also use the absolute command vi to open the profile
/bin/vi /etc/profile

Add the environment variable address in the system configuration file

export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
