Explain what the PATH environment variable is. Include the following points:
- In what file is the PATH variable usually set?
- Purpose of that variable
- Content of that variable

Consider the following scenario:
[gilles@sit-146 bin]$ echo $myVar
[gilles@sit-146 bin]$ myVar=”This is a string”
[gilles@sit-146 bin]$ echo $myVar
This is a string
[gilles@sit-146 bin]$ myVar=”$myVar . this part has just been added”
[gilles@sit-146 bin]$ cat test.sh
#!/bin/bash
#echo $myVar

Explain what will be displayed when you run the ./test.sh command? (Assume it has the execute bit set so that it runs).
