vim search and replace 03.13.06
Posted by wimac in computing.add a comment
Just a vim tip I felt like passing along…
:help :s
:[range]s[ubstitute]/{pattern}/{string}/[&][c][e][g][p][r][i][I] [count]
- For each line in [range] replace a match of {pattern} with {string}.
{string} can be a literal string, or something special; see ¦sub-replace-special¦.
When [range] and [count] are omitted, replace in the current line only.
When [count] is given, replace in [count] lines, starting with the last line in [range]. When [range] is omitted start in the current line.
Also see ¦cmdline-ranges¦.
See ¦:s_flags¦ for the flags.
:%s/s->/t->/g<CR>
In command mode (where <CR> is your return key)
Be aware of patterns (:help pattern)
I have a map in my .vimrc like this:
map gs :%s
Because :%s is so hard to type. To substitute globally you would, in command mode, do gs/foo/bar/g<CR>

CrackBerry users will not have to face the pains of messaging withdrawal thanks to a $613m settlement between Research in Motion (RIM) and NTP.
RIM paid up to settle all patent infringement claims made by NTP. In addition, it has acquired a perpetual license for NTP’s IP. Blackberry users everywhere will rejoice as it appeared RIM might have to shut down its messaging service as part of the ongoing dispute with NTP.

The MPAA filed lawsuits against Torrentspy, Isohunt, Torrentbox, Niteshadow and Bthub. This could have a huge impact on the Bittorrent community since Torrentspy and Isohunt are two of the most frequently visited torrent sites.
Chrooted SSH HowTo 02.04.06

This tutorial describes how to install and configure OpenSSH so that it will allow chrooted sessions for users. With this setup, you can give your users shell access without having to fear that they can see your whole system. Your users will be jailed in a specific directory which they will not be able to break out of.
