converts RAW files from a Nikon DSLR to jpg for easy viewing etc.

requires ufraw package

sudo cat /dev/vcs1 | fold -w 80
2009-04-15 08:49:48
User: animoid
Functions: cat fold sudo

This will view the console and assumes the screen is 80 characters wide.

Use /dev/vcs2 for the next virtual console.. etc.

watch "dmesg |tail -15"
2009-04-14 03:13:17
User: Buzzcp
Functions: watch

Other logs can be monitored similarly, e.g.

watch "tail -15 /var/log/daemon.log"
find | sed -e "s/^.*\///" | awk ' BEGIN { FS=""} { print NF " " $0 } ' | sort -nrf | head -10
watch -n 1 "netstat -tpanl | grep ESTABLISHED"

User: klipz
Functions: awk cd grep

When you fill a formular with Firefox, you see things you entered in previous formulars with same field names. This command list everything Firefox has registered. Using a "delete from", you can remove anoying Google queries, for example ;-)

svn status | grep "^\?" | awk '{print $2}' | xargs svn add
yum erase `yum list installed | grep 'php'`
2009-04-13 12:58:16
Functions: grep

This is useful for remove all packages that are part of a common suite.

i=10;for o in *.mp3; do i=$(printf "%02d" $i); mv $o $i$o; ((i = $i + 2)); done
2009-04-13 12:33:52
User: bazzawill
Functions: mv printf

This command adds the numbers 10, 12, 14 to a bunch of mp3's in the current working directory. You can then run the command replacing the inital i=10 with i=11 to add 11,13,15 in another directory then mv the files together and the first files interweave with the second group of files. I used this to weave a backlog of a podcast with other podcast so I didn't get sick of one while I was catching up. I started at 10 because printf blows up with 0 padded numbers 08 and 09 which kind of makes the printf command redundant as it was used to pad numbers 1 - 9 so they would come first and not get sorted incorrectly

alias lg='ls --color=always | grep --color=always -i'
2009-04-11 23:15:12
User: kFiddle
Functions: alias grep
Tags: ls alias color grep

This is a simple command, but extremely useful. It's a quick way to search the file names in the current directory for a substring. Normally people use "ls *term*" but that requires the stars and is not case insensitive. Color (for both ls and grep) is an added bonus.

function v { if [ -z $1 ]; then vim; else vim *$1*; fi }
2009-04-11 23:06:43
User: kFiddle
Functions: vim
Tags: vim vi function

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.

This example, for example, produces the output, "Fri Feb 13 15:26:30 EST 2009"

find -writable
2009-04-11 22:16:35
User: kFiddle
Functions: find

Have a grudge against someone on your network? Do a "find -writable" in their directory and see what you can vandalize! But seriously, this is really useful to check the files in your own home directory to make sure they can't inadvertently be changed by someone else's wayward script.

info --vi-keys
2009-04-11 22:10:08
User: kFiddle
Functions: info

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.

User: kFiddle
Tags: less regex

Although less behaves more or less like vim in certain aspects, the vim regex for word boundaries (\< and \>) do not work in less. Instead, use \b to denote a word boundary. Therefore, if you want to search for, say, the word "exit", but do not want to search for exiting, exits, etc., then surround "exit" with \b. This is useful if you need to search for specific occurrences of a keyword or command. \b can also be used at just the beginning and end, if needed.

sudo killall -9 pulseaudio; pulseaudio >/dev/null 2>&1 &
2009-04-11 20:18:35
User: hank
Functions: killall sudo

Ever since the switch to pulseaudio, Ubuntu users including myself have found themselves with no sound intermittently. To fix this, just use this command and restarts firefox or mplayer or whatever.

find ~ -mtime +365 -exec mv {} /tmp/mybackup \;
2009-04-11 12:16:48
User: kayowas
Functions: find mv

This example uses the -exec option to move all matching files into a backup directory

$ perl -pi -e 's/\r\n/\n/g' <finelame>
2009-04-10 22:22:31
Functions: perl
Tags: perl dos2unix

Converts windows lined-style file to unix.

see http://en.wikipedia.org/wiki/Newline

Can be used to convert from linux2dos : just invert \r\n and \n.

svn status | grep '^?' | awk '{ print $2; }' | xargs svn add
2009-04-10 21:55:37
Functions: awk grep xargs
Tags: svn awk xargs

Lists the local files that are not present in the remote repository (lines beginning with ?)

and add them.
