Question

When you write your own shell scripts, it's handy to place them all into one directory and add that directory's name to the $PATH variable.

a) True
b) False

Answer 1

It is true that placing shell scripts in a single directory and adding it to the $PATH variable is practical for easy script execution. The $PATH variable helps the shell find executable files without needing the full path. One should be careful to maintain security when altering the $PATH.

Step-by-step explanation:

It is true that when you write your own shell scripts, it's practical to place them all into one directory and add that directory's name to the $PATH variable. The $PATH variable is an environment variable on Unix-like operating systems that specifies the directories the shell should search for executable files when a command is run. By adding your script directory to the $PATH, you enable yourself to run scripts located in that directory without specifying the full path.

This practice is not only convenient but also enhances productivity as you can quickly execute your scripts from any location in the terminal. However, for security purposes, ensure that the directory you add to the $PATH is secure and contains only trusted scripts, as adding directories willy-nilly can pose a security risk.
