Permission denied error while executing the shell script
While running the shell script, if we get "Permission denied" message we should give executable permission to the file.
Example
We can provide the executable permission by using the below command,
chmod +x filename.sh.
chmod (Change Mode) - Using chmod we can change the access permissions to file system objects.
+x - It makes the file executable.
