Effective Strategies to Overcome “Command Not Found” in Linux

When the “Command Not Found” message appears, your system is indicating it doesn’t know where to find the specified command. This might happen due to an incomplete PATH or a missing package. Here’s what you can do to rectify this:

1. Verify your PATH Environment Variable:

$ echo $PATH

Ensure that the directories which usually contain common user commands, such as /bin, /usr/bin, and /usr/local/bin, are included in your PATH environment variable.

2. Update your PATH:

$ export PATH=$PATH:/desired/directory

This command will append the specified directory to your existing PATH, allowing your system to recognize commands located there.

Additionally, verify the location of commands using utilities such as which or whereis:

$ which ls
$ whereis gcc

This reveals the paths to the respective commands, confirming their existence and location on your system.
