Open up vi or vim at the first instance of a pattern in [file]. Useful if you know where you want to be, like "PermitRootLogin" in sshd_config. Also, vi +10 [file] will open up a file at line 10. VERY useful when you get "error at line 10" type of output.
This lets you use your favorite vi edit keys to navigate your term. To set it permanently, put "set editing-mode vi" in your ~/.inputrc or /etc/inputrc.
Add this to .vimrc to automatically give scripts with a shebang (e.g., #!/usr/bin/perl) executable permissions when saving. Found @ http://stackoverflow.com/questions/817060/creating-executable-files-in-linux/817522#817522
Sprunge.us is a code/text sharing site like pastebin, but it is easy to post stuff from the command line.
How it works:
:w !command
In vim, w writes the current tab to a file when a filename is given afterwards, but if !command is given, the output is piped to the stdin of command.
curl -F "sprunge=<-" http://sprunge.us
curl is an HTTP client. The -F option does an HTTP post to the given address. The data in the quotes is passed in the post. The "sprunge=" part sets up a fieldname - the part that follows is what is associated with the name. The "<" tells curl to send data from the file descriptor that follows it. The "-" in bash is a file descriptor that points to stdin instead of an actual file; in this case, stdin is being piped in from vim. After we send the HTTP post to sprunge.us, it will give back a url that points to the data you just sent.
| xclip
xclip is a utility that lets you put stuff in your clipboard or selection buffer. This part uses a bash pipe ( | ) to redirect the stdout of the previous command to the stdin of the next command. So, we're capturing the URL that curl gave us and putting it into the selection buffer, ready to paste into IRC or a forum.
Notes:
Of course, for this to work, you must have curl (which comes by default on most distroes), and xclip installed.
When you share the url, you can append "?lang" to highlight and have line numbers. Check out http://sprunge.us/BZXV?log for line numbers and http://sprunge.us/BZXV?ruby for highlighting.
If you prefer to use ctrl-v (paste from clipboard) instead of middle-click (paste from selection buffer), look up options on xclip - you can do that.

% = buffer d = delete
I always add this to my .profile rc so I can do things like: "vim *.c" and the files are opened in tabs.
Info has some of the worst keybindings I've ever seen. Being a vim user, I attribute that to emacs influence. Use the --vi-keys option to use some of the vi keybindings, although this won't change all the keybindings. Use the "infokey" program to have more control over info keybindings.
This is a simple command for jumping to the matching brace, square bracket, or parentheses. For example, it can take you from the beginning of a function to the end with one key stroke. To delete everything between the pairs of {}, [], or (), issue the command:
d%
To replace text between pairs of braces, brackets, or parentheses, issue the command:
c%
You can also use this command to find out if an opening brace has been properly closed.
Sort lines within vi editor. In this example sort lines 33-61 and lines 4-9 asciibetically. Show Sample Output
the middle command between the ; and ; is the vi commands that insert that line into the last line of the file, the esc with the carets is literally hitting the escape key, you have to have the smbfs package installed to do it, I use it to access my iTunes music on my mac from my linux PC's with amarok so I can play the music anywhere in the house. among other things, it allows you to access the files on that share from your computer anytime you're on that network.
Within vi allow to empty a text file in one shot
vix /tmp/script.sh
Open a file directly with execution permission.
Put the function in your .bashrc
You can also put this in your vimrc:
command XX w | set ar | silent exe "!chmod +x %" | redraw!
and open a new file like this:
vi +XX /tmp/script.sh
Helps when I'm editing a script and want to double check some commands without having to exit out of vi multiple times or having to use another terminal session.
Use sed to comment out any up/down bindings in zsh
Deletes lines to of a file. You must put the end line first in the range for the curly brace expansion, otherwise it will not work properly. Show Sample Output
Deletes lines from START to END, inclusive. For example +4,10d will delete line 4, 5, ..., 10. Just like the vi command :4,10d does it.
you don't have to spell out numbers, you can just use nu
Reduce the number of keystrokes it takes to open a file in vim. First of all, you just need to type "v", which is less than half the number of characters (!), and second-of-all, you only need to enter a substring of the file you want to open. For example, if you want to open the file, homework.txt, then type "v hom" to open it. Good tip is to use the lowest unique substring, otherwise you'll open multiple files in different buffers (which is sometimes desirable). Use Ctrl-^ to switch between buffers.
