Get primary IP of the local machine

Plenty of commands out there for finding external IP, but sometimes getting the [internal] IP bound to the NIC handling Internet traffic is useful. Probably not production worthy, but a useful quick kludge. Assumes IPv4 and no fancy routing. Show Sample Output

Shows the online version of docker's man related a command

Docker's local man pages are (often) half of what you have online, so I wanted that as local man. Install lynx and run my oneliner, then use as follows: dockpage Adjust lynx's page width at will Show Sample Output

Stop a container by sending SIGTERM and then SIGKILL after a
grace period

Find & remove files that are duplicates but with different extensions recursively

Very useful to get rid of backup files or wrong extension files that lure in your folders In this example first I do two searches for all filenames of the two extensions .jpg and .png, then delete the extension and only output the now duplicate files. I loop with these results and print a log and delete the file with the extension I dislike. Show Sample Output

Remove color codes (special characters) with sed

This command builds upon some of the original commands posted here. Additions - The control sequence \x1b(B which selects the default character set ASCII. - Either the \x1B style escape sequence or the \033. - Case insensitivity by using 'I' to include \x1b, \x1B escapes and a-zA-Z in the latter part Tested extensively on makefile unbuffered output where the above additions proved necessary

Convert rich text on the clipboard to Markdown in OS X

This is useful for converting a piece of text from a browser or a PDF reader to Markdown. pbpaste -Prefer rtf no longer works for getting the rich text version of the clipboard. markdown_strict uses Markdown.pl syntax without Pandoc extensions. --no-wrap disables hard wrapping and --atx-headers uses ATX headers instead of SETEX headers. You can also use osascript -e'get the clipboard as"HTML"'|sed 's/«data HTML//;s/»//'|xxd -r -p to get an HTML version of the clipboard which is included for text copied from a web view in applications like Safari and Chrome.

Cleanup remote git repository of all branches already merged into master

Stream YouTube URL directly to mplayer.

This is the result of a several week venture without X. I found myself totally happy without X (and by extension without flash) and was able to do just about anything but watch YouTube videos... so this a the solution I came up with for that. I am sure this can be done better but this does indeed work... and tends to work far better than YouTube's ghetto proprietary flash player ;-) Replace $i with any YouTube ID you want and this will scrape the site for the _real_ URL to the full quality .FLV file on Youtube's server and will then will hand that over to mplayer (or vlc or whatever you want) to be streamed. In some browsers you can replace $i with just a % or put this in a shell script so all YouTube IDs can be handed directly off to your media player of choice for true streaming without the need for Flash or a downloader like clive. (I do however fully recommend clive if you wish to archive videos instead of streaming them) If any interest is shown I would be more than happy to provide similar commands for other sites. Most streaming flash players use similar logic to YouTube. Edit: 05/03/2011 - Updated line to work with current YouTube. It could be a lot prettier but I will probably follow up with another update when I figure out how to get rid of that pesky Grep. Sed should take that syntax... but it doesn't. Original (no longer working) command: mplayer -fs $(echo "http://youtube.com/get_video.php?$(curl -s $youtube_url | sed -n "/watch_fullscreen/s;.*$video_id.\+$&title.*;\1;p")")

Fast command-line directory browsing

After typing cd directory [enter] ls [enter] so many times, I figured I'd try to make it into a function. I was surprised how smoothly I was able to integrate it into my work on the command line. Just use cdls as you would cd. It will automatically list the directory contents after you cd into the directory. To make the command always available, add it to your .bashrc file. Not quite monumental, but still pretty convenient.

convert ascii string to hex

just a bit simpler

Converts all windows .URL shortcuts in a directory to linux (gnome) .desktop shortcuts

Get your mac to talk to you

Very entertaining when run on someone elses machine remotely ;)

Stream audio over ssh ogg version

Stream OGG vorbis over ssh.

Search for files in rpm repositorys. (Mandriva linux)

Look for an rpm that supplies a specific file that you don't yet have installed. extremely useful when you need something and don't know where it is.. or what its called. note: uses grep like syntax.

Get just the IP for a hostname

Colored status of running services

Replace service --status-all 2>&1 by service --status-all 2>/dev/null to hide all services with the status [ ? ]

Convert entire audio library in parallel

Uses parallel processing Reiteration of my earlier command https://www.commandlinefu.com/commands/view/15246/convert-entire-music-library Usage lc Old_Directory New_DIrectory Old_Format New_Format lc ~/Music ~/Music_ogg mp3 ogg
