Quickly batch resize images

Use curl on Windows to bulk-download the Savitabhabhi Comic Strip (for Adults)

Bulk downloads the comic strip JPG files for the adult cartoon Savitabhabhi, storing each set in it's own folder. Requires manual removal of "non-image" files that maybe created because each series may differ in length. The command can be easily adapted for UNIX flavours. You need to have cURL in your path.

Update twitter via curl (and also set the "from" bit)

An improvement of the original (at: http://www.commandlinefu.com/commands/view/2872/update-twitter-via-curl) in the sense that you see a "from cURL" under your status message instead of just a "from API" ;-) Twitter automatically links it to the cURL home page. Show Sample Output

Normalize volume in your mp3 library

Execute this in the root of your music library and this recurses through the directories and normalizes each folder containing mp3s as a batch. This assumes those folders hold an album each. The command "normalize-audio" may go by "normalize" on some systems.

Shorten url with is.gd using curl, perl

// This is description for the old command: Unfortunately we to encode the URL. It can't be done with bash (without building it ourselves) so I used Perl? Example with Perl: curl -s http://is.gd/api.php?longurl=`perl -MURI::Escape -e "print uri_escape('http://www.google.com/search?hl=en&source=hp&q=commandlinefu&aq=0&oq=commandline');"` Example without Perl: curl http://is.gd/api.php?longurl=http://www.google.com Most urls doesn't use & and ? anymore (SEO etc) so in most cases you can just use the simple version. :) Show Sample Output

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

add files to existing growable DVD using growisofs

replace "directory name with files to add to DVD" with actual directory containing files you want to add to growable DVD

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Update all packages installed via homebrew

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Better recursive grep with pretty colors... requires ruby and gems (run: "gem install rak")

Unlock your KDE4.3 session remotely

The unlock command for KDE 4.3 has changed from krunner_lock, this process doesn't exist anymore. So here's the update :-) If qdbus complains about not being able to find X, put a "DISPLAY=:0 " (:0 being your X server display) in front of the command.

Multi-thread any command

For instance: $ find . -type f -name '*.wav' -print0 |xargs -0 -P 3 -n 1 flac -V8 will encode all .wav files into FLAC in parallel. Explanation of xargs flags: -P [max-procs]: Max number of invocations to run at once. Set to 0 to run all at once [potentially dangerous re: excessive RAM usage]. -n [max-args]: Max number of arguments from the list to send to each invocation. -0: Stdin is a null-terminated list. I use xargs to build parallel-processing frameworks into my scripts like the one here: http://pastebin.com/1GvcifYa

a fast way to repeat output a byte

the speed is about 500MB/s on my machine. i think it's fast enough to output not too many bytes. while a C program may output 1GB per sencond on my machine. if the size is not the power of 512,you may change the bs and count in dd.

Emulating netcat -e (netcat-traditional or netcat-openbsd) with the gnu-netcat

Then just nc servername 2600 and ./script.sh kill the client with ctrl+c. You can reconnect several times. kill the server with exit
