== 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.
