Of course it requires import command, from imagemagick tools, but it's simpler to type, and imagemagick is usefull anyway.

vi +/pattern [file]

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.

apt-get install most && update-alternatives --set pager /usr/bin/most

User: aurium
Functions: apt install

That command installs "most" and make this command as the default man reader. The "most" works like "less" (the current man reader), but it render colors for manpages and may do more things. Read "man most".

You can see a preview here: http://www.dicas-l.com.br/dicas-l/20090718.php

connects to host via ssh and displays the live transfer speed, directing all transferred data to /dev/null

needs pv installed

Debian: 'apt-get install pv'

Fedora: 'yum install pv' (may need the 'extras' repository enabled)

You can use [n]> combined with >(cmd) to attach the various output file descriptors to be the input of different commands.

doesn't require "at", change the "2h" to whatever you want... (deafult unit for sleep is seconds)

cd !$:h

User: lingo
Functions: cd
25

Uses the last argument of the last executed command, and gets the directory name from it.

Use $!:t for the filename alone, without the dirname.

perl -e 'print "P1\n256 256\n", map {$_&($_>>8)?1:0} (0..0xffff)' | display

OK, not the most useful but a good way to impress friends. Requires the "display" command from ImageMagick.

List all file opened by a particular command based on it's command name.

lynx -accept_all_cookies -cmd_script=/your/keystroke-file
2009-03-17 00:38:36
User: Alanceil
25

This command will tell lynx to read keystrokes from the specified file - which can be used in a cronjob to auto-login on websites that give you points for logging in once a day *cough cough* (which is why I used -accept_all_cookies).

For creating your keystroke file, use:

lynx -cmd_log yourfile
$ grep -rl oldstring . |xargs sed -i -e 's/oldstring/newstring/'
2009-03-03 20:10:19
User: netfortius
Functions: grep sed
Tags: perl sed
25

recursively traverse the directory structure from . down, look for string "oldstring" in all files, and replace it with "newstring", wherever found

also:

grep -rl oldstring . |xargs perl -pi~ -e 's/oldstring/newstring'
xset dpms force standby
netstat -ant | awk '{print $NF}' | grep -v '[a-z]' | sort | uniq -c

This is shorter and actually much faster than >/dev/null (see sample output for timings)

Plus, it looks like a disappointed face emoticon.

file -s /dev/sd*

file(1) can print details about certain devices in the /dev/ directory (block devices in this example). This helped me to know at a glance the location and revision of my bootloader, UUIDs, filesystem status, which partitions were primaries / logicals, etc.. without running several commands.

See also:

file -s /dev/dm-* file -s /dev/cciss/*

etc..

rm *.txt <TAB> <TAB>

alternative for "echo rm *.txt". Just doubletab the command you are willing to use and it will show you the affected files.

PROMPT_COMMAND='if [ $RANDOM -le 3200 ]; then printf "\0337\033[%d;%dH\033[4%dm \033[m\0338" $((RANDOM%LINES+1)) $((RANDOM%COLUMNS+1)) $((RANDOM%8)); fi'

Add this to a fiend's .bashrc.

PROMPT_COMMAND will run just before a prompt is drawn.

RANDOM will be between 0 and 32768; in this case, it'll run about 1/10th of the time.

\033 is the escape character. I'll call it \e for short.

\e7 -- save cursor position.

\e[%d;%dH -- move cursor to absolute position

\e[4%dm \e[m -- draw a random color at that point

\e8 -- restore position.

This function displays the latest comic from xkcd.com. One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic.

To get a random xkcd comic, I also use the following:

xkcdrandom(){ wget -qO- dynamic.xkcd.com/comic/random|tee >(feh $(grep -Po '(?<=")http://imgs[^/]+/comics/[^"]+\.\w{3}'))|grep -Po '(?<=(\w{3})" title=").*(?=" alt)';}

Yeah I know it's been up here a million times, but this service is a really clean and nice one. Nothing but your IP address on it. Actually I was to write something like this, and noticed this on appspot... ;)

this bzips a folder and transfers it over the network to "host" at 777k bit/s.

cstream can do a lot more, have a look http://www.cons.org/cracauer/cstream.html#usage

for example:

echo w00t, i'm 733+ | cstream -b1 -t2

hehe :)
