differences of commands
 

what is the difference between the commands ls-l and
ls-al used in linux.

Read the man page for ls to see what the a and l options do.

-l is long format, ls -l will list the permissions, ownership and dates of the contents of the directory. -a will also list the hidden files so ls -la will list the contents, including the hidden contents, in long form. The hidden files generally start with . If you do ls -a in your home directory you will see your user software files such as .gnome .mozilla, .realplayer .xmms, .kde Your user gnome settings are stored in .gnome etc.

Hello and welcome to LQ. If you do not know what a command or a command switch does, then I think its best to read the manual or info page. On most distros you would do something like "man command" to find out what the command and its switches do.
