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

```
# dockpage stop
Usage: docker stop [OPTIONS] CONTAINER [CONTAINER...]

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

  --help             Print usage
  -t, --time=10      Seconds to wait for stop before killing it

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

This is useful in teams where developers don't bother to remove branches after merging PR. These branches make it hard to seek for really useful branches, which gives us a nice value of finding and exploring other people's code even before they create PR for it.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Create a pdf version of a manpage

Quick and dirty version. I made a version that checks if a manpage exists (but it's not a oneliner). You must have ps2pdf and of course Ghostscript installed in your box. Enhancements appreciated :-)

IFS - use entire lines in your for cycles

When you use a "for" construct, it cycles on every word. If you want to cycle on a line-by-line basis (and, well, you can't use xargs -n1 :D), you can set the IFS variable to .

Create a Multi-Part Archive Without Proprietary Junkware

Leave it to a proprietary software vendor to turn a cheap and easy parlor trick into a selling point. "Hey guys, why don't we turn our _collection of multiple files_ into a *collection of multiple files*!!" Extract the ^above with this: $ cat pics.tar.gz.??? | tar xzv ^extract on any Unix - no need to install junkware! (If you must make proprietary software, at least make it do something *new*) if [ -e windows ]; then use 7-Zip

Show numerical values for each of the 256 colors in ZSH

This will show a numerical value for each of the 256 colors in ZSH. Everything in the command is a ZSH builtin, so it should run on any platform where ZSH is installed. Prints one color per line. If someone is interested in formatting the output, paste the alternative.

Print the 10 deepest directory paths

Increment the filename of png in a given directory by one

Grab IP address on machine with multiple interfaces

Instead of hard-coding in a check to scrape info from ifconfig based on a specific interface, do it in a more portable way. This works really well if you switch between wired, wireless, bluetooth or even VPN connections. You can get your current IP in a script (since it'll be something like tun0 instead of eth0 or wlan1). This uses a well known public ip address 8.8.8.8, but it doesn't actually connect to it, it just shows you the route it would take.

Find default gateway

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

remote-pbzip2 and transfer a directory to local file
