If you get the error while opening a file in vi,

“There is not enough space in the file system.
[Press return to continue]”

and you know that you have space in your home directory, than simply use this command
in vi, say

:set dir=

then press:

:e .

You will be able to see the entire file.

Ever want to run some shell commands while doing a vi edit session? Like, “what’s the name of that file” I want to use in this script I’m making?

Instead of exiting vi; doing the ls filenamepart*, and going back into vi, you can from a vi session:

enter “:”, then enter “shell”.

This suspends the vi session and gives you a command prompt where you can use any shell command. When finished, enter the “exit” command and you will be returned to the vi session.

You can go to a particular line or word in a file using vi in several ways:

• To make vi start at a particular line in a file, add +line_num to the command you use to start vi. Replace line_num with the line number, for example: vi +36 foo.c
• If you’re already in vi, you can use the goto command. To do this, press Esc, type the line number, and then press Shift-g . If you press Esc and then Shift-g without specifying a line number, it will take you to the last line in the file.
• You can also use the ex command line to go to a line. For instance, if you wanted to go to line 14, you could press Esc and then enter: :14
• To search forward for some text, use the / (forward slash) command. Press Esc and then enter /pattern , replacing pattern with the text for which you want to search forward. For example, to find every instance of the word “blimp”, enter: /blimp To look for the next occurrence after the first, either press n or press / again and then press Enter. To go back to a previous occurrence, press Shift-n . To search backwards in a file, use the ? command.
• To see what line you’re on at any time, press Ctrl-Shift-g . To number all lines, press Esc and enter: :set number

In Vi or Vim, use the forward slash </> to search. Then type in your search string and hit <Enter>. You can navigate through occurrences of your search string using <n> to move forward and <N> to move backwards.
