Shell script: how to check read only file mode.
 

Good Day,

How do check if the file is read only?

I know if we need to check executable we do

.

Same way can we check if the file is read only.

Thanks.

Look at "man test" ("[" is a synonym for "test")

-e is not for executable--it checks to see if the file exists

Thank you.

I did check man test.

its -w.

the existential -e test but what of -f ?
 

Doesn't -f purport to check if a file is a file, oh, i just answered my own question:
-e checks to see if ANY file (directory or otherwise) exists answering to the name in the <filename>; whereas:
-f checks to see if the file in question is in fact a normal file

Would that be right?
