export PATH="$HOME/bin:$PATH"
Execute the source control to save the file with the change nosotros fabricated into the $PATH. This command will as well load the new path in the current session of the Linux final.
Again, print out the value of $PATH for the confirmation of the changes.
The output declares that the $PATH is successfully changed in the Linux terminal.
