Making a file Read-only

Kujila · 02-07-2004, 08:15 PM

I need to make a file read-only, so that this Windows program I'm using in WINE doesn't re-make the file that causes tself to crash.

I want to make the 0 byte, empty file without letting the WINE program over-write it with its version.

Thanks.

touch <filename> = creates file (will have 0 bytes as size)
chmod 444 <filename> = makes read only

Oop... The Windows program (under WINE) somehow managed to write a few bytes to it! :-X

Really? When you type ls -la <file-name> what does it show for the permissions?

la <filename>

just shows me the filename again, with no additional information.

-la is not found as a command

ls -la <filename>

The above line is the command.

(ACK! Sorry, didn't see the "ls" on your previous post, and I'm pretty Linux-newbie anyways! )

-r-------- 1 root root 0 Feb 7 21:07 custom.hpk

I am logged in as "root".

This is a good example of why not to run as root.

That was very helpful indeed.
