How to check execute permissions?

To check execute permissions for a file in a shell script, you can use the -x option in a conditional expression. Here's an example:

filename="test_file.txt"
if [ -x "$filename" ]; then
    echo "You have execute permissions for $filename."
else
    echo "You do not have execute permissions for $filename."
fi

In this code:

• The -x option checks if the file specified by filename is executable.
• If the file is executable, the message indicating execute permissions will be printed; otherwise, a message indicating lack of execute permissions will be shown.
