Mastering Linux Shell Scripting - Second Edition

Checking files and directories

Similarly, you can check files and directories using the if statement.

Let's look at an example:

#!/bin/bash 
mydir=/home/mydir 
if [ -d $mydir ] 
then 
echo "Directory $mydir exists." 
else 
echo "Directory $mydir not found." 
fi 

We used the -d test to check if the path is a directory.

The rest of the tests work the same way.
