How do you CHMOD on OSX?

chmod 777 <filename>

hang on, this is a doc on a remote computer you need to chmod?

or is the file on your machine?

if its on the remote machine you need to do the following:
1, open terminal (applications:utilities)
2, type SSH -l <account name on remote server> <IP/DNS of remote server> (for example ssh -l badger 62.31.22.145 OR ssh -l badger http://www.reallydull.com> (no these are *NOT* valid accounts - only examples )
3, enter your password
4, type cd <location of file> (eg cd /~/reallycoolapp/ (the ~ denotes your home directory))
5, type chmod 777 <filename>
6, type ./<filename>

if the file is on your OSX machine omit steps 2 and 3.

did it work ?

Can't you also do it using the "Get info" contextual menu? This is perhaps slightly easier than using the terminal for someone new to Unix. In this case 777 means read and write permission to everyone.

edit: oops, didn't see that it was on linux. Forget about my post.

you're absolutely right, I do meany ~/reallycoolapp/

Well, I meant in OS X you needn't use the terminal to change permissions. You can do it from Aqua. Using linux, I don't know if your window manager makes this possible. Most probably it can only be done using the terminal (and this is what most linux users do anyway, isn't it?)

Sure he could do it in X - however I'm guessing he dosn't had X available to him

Most of the time unless you are going to really get into the Unix of Mac OS X you don't want to Chmod. Mac OS X's operating system and applications have very specific permissions that you don't want to mess around with. With Mac OS X 10.1.5 and up you can run an Apple utility to fix permissions to match the template of the operating system's expected permissions:

http://docs.info.apple.com/article.html?artnum=106900
for Mac OS X 10.1.5.

and for Mac OS X 10.2 and up, use the Applications -> Utilities -> Disk Utility -> First Aid tab -> select the hard disk and hit the Repair Permissions button if your machine will boot to the desktop. One method to fixing some machines that won't boot the hard disk with 10.2 and up is use the Mac OS X 10.2 installer CD's Disk Utility in the Installer menu.

There is a utility called batchmod which will modify permissions in batch, if you know what you are doing. People who don't can render their whole system unbootable. Batchmod is here:

Only use it if you are sure what you are doing. One of my friends used it and not only made his hard drive unbootable, but also his CD drive!

open the terminal (Applications folder)

type the following:

man chmod

this will give you the manual (man) for chmod (command).

you can use this for just about any unix based utility in OS X or linux or BSD.

There is also a utility out there somewhere called "batmod" I believe.
It works well.
