Following command can be used to check if file locking is working in a particular directory in Linux. Replace /tmp with the directory name as needed where you have to create test-lockfile. Below command will clean the test-lockfile as well once the test is done.
cd /tmp;flock test-lockfile -c 'echo Success :::: File lock acquired';\rm /tmp/test-lockfile
Sample Output.
Success :::: File lock acquired
If the test is unsuccessful you will see Permission denied errors.
