If you run the command "ls -l filename", you'll see the file in question
with a row of letters and dashes on the left-hand side, something like:
-rw-r--r--
The first symbol is the type of file (directory, link, etc).
The next 3 tell you what the owner of the file can do with it.
The next 3 tell you what the group members of the file can do with it.
The next 3 tell you what all other users of the file can do with it.
The rights are:
r: ability to read
w: ability to write
x: ability to execute
To make a file writable by anyone, you just give the "w" permission
to everybody:
chmod ugo+w filename
To make a file writable only by its owner, you take permission away
from everybody else:
chmod go-w filename
You can shorthen this by using numbers to represent the permissions.
r = 4
w = 2
x = 1
r+w = 4+2 = 6
r+w+x = 4+2+1 =7
etc...
So, to make a file readable and writeable by anyone, you could just type:
chmod 666 filename
There's a lot more to file permissions than this and I'ld recommend
reading the man page to chmod to learn more.
