| 3 | 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. |

| 5 | === Loggin in to other machines with SSH === |
| 6 | |
| 7 | The `ssh` command can be used to log in to other machines, or from a mac to the grid: |
| 8 | |
| 9 | {{{ |
| 10 | $ ssh usernam@host |
| 11 | }}} |
| 12 | |
| 13 | === List files === |
| 14 | |
| 15 | To list the files in the current directory: |
| 16 | |
| 17 | {{{ |
| 18 | $ ls |
| 19 | }}} |
| 20 | |
| 21 | To get more information about every file, do |
| 22 | |
| 23 | {{{ |
| 24 | $ ls -l |
| 25 | }}} |
| 26 | |
| 27 | To get information about a specific file or directory (you could add -l too) |
| 28 | |
| 29 | {{{ |
| 30 | $ ls filename |
| 31 | }}} |
| 32 | |
| 33 | === Change working directory === |
| 34 | |
| 35 | {{{ |
| 36 | $ cd path |
| 37 | }}} |
| 38 | where path is the directory you want to change to, eg |
| 39 | {{{ |
| 40 | $ cd /proj/my-project |
| 41 | }}} |
| 42 | |
| 43 | To print the current working directory use `pwd`. |
| 44 | |
| 45 | There are two "special directories": `.` and `..`. The first corresponds to the current directory, the second corresponds to the directory above the current directory. |
| 46 | |
| 47 | Finally, |
| 48 | {{{ |
| 49 | $ cd |
| 50 | }}} |
| 51 | without any arguments will return you to your home directory. |
