CS1K Rel 6 - Linux Command Line Notes


Home Directory

Locating Files

To change directories you use the cd command, but to make life easier and save typing, you can use the <TAB> key to automatically add the directory. Try this:- Type "cd /v" then hit the <TAB> key. Because there is only one directory begining with "v" the system will automatically change the line to "cd/var/" if you want to go further you can add the first letter of the next directory e.g. "cd /var/o" and again hit the <TAB> key. The line will not be updated to "cd/var/opt/" you can keep going till you have the full directory path. If there are two options, the system will BEEP and you will need to add another character and <TAB> again. This technique can also be used with commands such as copy (cp).
