4.4 Set permissions to the ibay mp3 as in the original. For help on this, look at [http://www.ss64.com/bash/chmod.html ss64] or [http://www.oreillynet.com/linux/cmd/cmd.csp?path=c/chmod oreillynet]. The "-R" (optional) means recursive, subdirectorys will be included in the command.

== Notes about file permissions ==
=== Basic style ===
<code>---------</code> = 3+3+3 positions
'''Position'''
<br>rwx------ = First set describes owner permissions
<br>---rwx--- = Second set describes group permissions
<br><code>------rwx</code> = Third set describes user permissions
'''Permissons and positions in a set'''
<br>r-- = read
<br>-w- = write
<br>--x = execute
=== 3 digit style ===
000 = 3 positions
'''Position'''
<br>n-- = owner
<br>-n- = group
<br>--n = user
'''Permission'''
<br>read = 4
<br>write = 2
<br>execute = 1
Permissions are added together to a sum for one position.
=== Translate basic style to a 3-digit style ===
'''Position'''
<br>First set = first digit = owner
<br>Second set = second digit = group
<br>Third set = third digit = user
'''Permission'''
<br>r = read = 4
<br>w = write = 2
<br>x = execute = 1
=== Examples ===
<code>---------</code> = 000 [owner=0+0+0][group=0+0+0][user=0+0+0] Nobody can do anything.
r--r--r-- = 444 [owner=4+0+0][group=4+0+0][user=4+0+0] Everybody can read.
-w--w--w- = 222 [owner=0+2+0][group=0+2+0][user=0+2+0] Everybody can write.
--x--x--x = 111 [owner=0+0+1][group=0+0+1][user=0+0+1] Everybody can execute.
rw-rw-rw- = 666 [owner=4+2+0][group=4+2+0][user=4+2+0] Everybody can read and write.
rwxr----x = 741 [owner=4+2+1][group=4+0+0][user=0+0+1] Owner can read, write and execute. Group can read. User can execute.
rwxrwxrwx = 777 [owner=4+2+1][group=4+2+1][user=4+2+1] Everybody can read, write and execute.
rwxrwxr-x = 775 [owner=4+2+1][group=4+2+1][user=4+0+1] Owner can read, write and execute. Group can read, write and execute. User can read and execute.
