== Unix Cheat Sheet ==

To log in to the grid, you need to use PuTTY if you use a PC, or, in the case of a mac, you can log in from the terminal. 

=== Loggin in to other machines with SSH ===

The `ssh`  command can be used to log in to other machines, or from a mac to the grid:

{{{
$ ssh usernam@host
}}}

=== List files ===

To list the files in the current directory:

{{{
$ ls
}}}

To get more information about every file, do

{{{
$ ls -l 
}}}

To get information about a specific file or directory (you could add -l too)

{{{
$ ls filename
}}}

=== Change working directory ===

{{{
$ cd path
}}}
where path is the directory you want to change to, eg
{{{
$ cd /proj/my-project
}}}

To print the current working directory use `pwd`.

There are two "special directories": `.` and `..`. The first corresponds to the current directory, the second corresponds to the directory above the current directory.

Finally, 
{{{
$ cd
}}}
without any arguments will return you to your home directory.
