  • Doesn't display the matching line. If you want that behaviour, you need to add "print && " before the 'exit'.

    <command> | perl -pe '/<regex/ && exit;'

  • "Copying" things to the X clipboard doesn't normally create a copy. Rather the data to be 'copied' is referenced. This means that if the application that you 'copied' stuff from is closed, that data is lost. If the application that you 'copied' from is suspended with CTRL-Z, there could be some issues if you try to paste it into something. This command will create a copy of referenced data and have xclip be the provider of it, so you can then go ahead and close the app that contains the original information. Caveat: I'm not sure if this is binary-safe (though i would expect it to be), and don't know what would happen if you used it to clip a 20 meg gimp image. This technique becomes more convenient if you set it up as an action in a clipboard manager (eg klipper, parcellite). Some of these applets can take automatic action based on a variety of parameters, so you could probably just get it to always own the clipped data whenever data is clipped.

    xclip -o -selection clipboard | xclip -selection clipboard

  • Manpages, command summaries, and pretty much everything else usually have the information you're most likely to want at the beginning. Seeing just the last 40 or so lines of options from a command that has 100 is not super useful, and having to scroll up each time you want to glance at something is spastic. Run this and then do something like p do vi --help and you'll get the first screen(-mostly-)full of vi's usage info and options list Then use p d to page down, and p u to page up. To see the current page again: p r Also useful for situations like p do aptitude search ~dsmorgasbord p next #p sudo aptitude -r install libwickedawesome-perl-snoochieboochies p next p sudo aptitude -r install libwickedawesome-perl-snoochieboochies snazztasticorama-dev-v0.&#8734; where you're using readline up-arrow, HOME, END, etc., to quickly recall commented commands. For the unaware, that option to aptitude search will bring up all of the packages whose descriptions contain the string "smorgasbord". Depending on your distro, there could potentially be hundreds of them.

    p() { l=$LINES; case $1 in do) shift; IFS=$'\n' _pg=( $("$@") ) && _pgn=0 && p r;; r) echo "${_pg[*]:_pgn:$((l-4))}";; d) (( _pgn+=l-4 )); (( _pgn=_pgn>=${#_pg[@]}?${#_pg[@]}-l+4:_pgn )); p r;; u) (( _pgn=_pgn<=l-4?0:_pgn-$l-4 )); p r;; esac; }

  • Assuming that $script contains the filename of a script you'd like to post as part of a comment on this site, this will prefix each line with '$' and pipe it into the X selection. From there just put the cursor in the right place in the comments box and middle-click. Should work pretty much anywhere with xclip installed. On debian-ish systems this is installed as part of the package "xclip".

    sed 's/^/$ /' "$script" | xclip

Find the cover image for an album
This bash function uses to find the cover for an album. It returns an url to the image. Usage: albumart [artist] [album] These arguments can be reversed and if the album name is distinct enough, it may be possible to omit the artist. The command can be extended with wget to automatically download the matching image like this: $ albumart(){ local x y="$@";x=$(awk '/View larger image/{gsub(/^.*largeImagePopup\(.|., .*$/,"");print;exit}'

Stream the latest offering from your fave netcasts/podcasts
This is a quick line to stream in the latest offerings of your favorite netcasts/podcasts. You will need to have a file named netcast.txt in the directory you run this from. This file should have one and only one of your netcast's/podcst's url per line. When run the line grabs the offering on the top of the netcast/podcast stack and end it over , quietly, to vlc. Since I move around computers during the day I wanted an easy way to listen to my daily dose of news and such without having to worry about downloading to whatever machine I am on. This is just a quick grab and stream of whats current. Future plans... have the list of netcasts be read from the web. possibly an rss or such. I use greader so there might be a way to use it as the source so as not to have to muck with multiple lists

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.
