Hi guys,

I got a problem here.
On a linux platform when we type: "ls -lt"
It will show a list of files in that directories, in addition to that on the left side of each file, there is a something like this: "-rw-rw-r--".
I want to know how to edit this, i.e. to change the status of this string.
Pls advise.
I need it urgently.
Thank YOu very much.

Regards
Kelvin Loo

What your asking about is referring to the read, write and execute permission levels.
To change the status you would type something like this at the command:

# chmod 666 (whatever file you want to change here)
Like that above using 666 would change the string to look like -rw-rw-rw-, where this file would then only be read, write but no execution of the file. A 777 would make it -rwxrwxrwx. The r has a value of 4, w has 2 and the x is 1.
if you wanted it to look like this -rwxr--r--, it would be 744 after the chmod. Do you catch my drift on how to set this?

You can do a man chmod to learn the permission levels of each and how to set them. But remember, chmod changes this.
