• Empty Output: If the current directory is empty, get_current_dir_name will return an empty string.
• User Permissions: The command may fail if the user does not have read permissions for the current directory.

Integration

• Use get_current_dir_name with cd to change directories relative to the current location:

current_dir=$(get_current_dir_name)
cd $current_dir/Documents

• Combine get_current_dir_name with other commands like find or ls to perform file operations:

find $(get_current_dir_name) -name "*.txt"
