Linux:-bash: * * *: Command not found, the system many commands are not used, are prompted not to this command.
All of a sudden, Linux has many commands that are not used, prompting for no such command.
This should be caused by a problem with the system environment variable.
Workaround:
First Use: Echo $PATH
See if path contains:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
If not
Use temporary environment variables (disappear after reboot)
#export path= $PATH:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
Then you can use those commands to go in and modify the persistent environment variable:
1. Modify Profile: (All users)
#vi/etc/profile
Join: Export path= $PATH:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
Save exit.
2. Modify the. bashrc file: (Individual users)
#vi/~/.BASHRC (available per user directory, Ls-all)
Join: Export path= $PATH:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
Save exit.
Reboot the system and fix it.
You can also use the command without restarting: #source. BASHRC
To make the environment variable that you just modified take effect
Linux:-bash: * *: Command not found
