Git reset added new files

1. No for-loop, but xargs. 2. Append "--" in git-reset HEAD command to deal with filenames contained leading hyphen/minus sign (-). 3. Add "--porcelain" option in git-status command for easy-to-parse format when scripting. 4. Add "--no-run-if-empty" option in xargs command to prevent you run it twice and accidentally reset all staged changes. 5. Use zero byte (NUL character) as line terminator instead of newline (\n) to make it more robust to deal with filename with whitespaces. pipe#1: git-status. pipe#2: Use "grep" to filter out "non-added" files. pipe#3: use "sed" to Trim out the leading three characters, reserve the filename. pipe#4: xargs + git-reset... p.s. The "HEAD" in git-reset can be omitted . And, maybe, the third part of this shell pipe (sed) has potential to be enhanced.

Get just LAN IP without all the extra stuff

I just needed to store the LAN IP (for ipv4) in a variable for a specific task in a bash script. I figured I'd share. I sent it to a variable with VAR=$(stuff) and used it later on. I put the exit 0 in the if statement to make it so that it breaks if there are more than one IPv4 addresses assigned. I only wanted the first one. Edit: Bear in mind, my network mask is a double digit number so if you have a smaller nw mask you'd need to edit the sed statement. Show Sample Output

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.

list all opened ports on host

in loop, until the last port (65535), list all opened ports on host. in the sample I used localhost, but you can replace with any host to test.

a function to find the fastest DNS server

http://public-dns.info gives a list of online dns servers. you need to change the country in url (br in this url) with your country code. this command need some time to ping all IP in list.

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"

Search some text from all files inside a directory

Quick way to sum every numbers in a file written line by line

If you have a file full of numbers written line by line, you can sum every line to get the total. With a file like this: 3443535 9878977 67554 987798 232324 you will got: 14610188

a function to create a box of '=' characters around a given string.

First argument: string to put a box around. Second argument: character to use for box (default is '=') Same as command #4948, but shorter, and without the utility function.

Recall last argument of previous command

!$ recalls the last argument of the previous command. This is very useful when you have to operate several operations on the same file for example.

Choose from a nice graphical menu which DI.FM radio station to play

This is a very simple and lightweight way to play DI.FM stations For a more complete version of the command with proper strings in the menu, try: (couldnt fit in the command field above) $zenity --list --width 500 --height 500 --title 'DI.FM' --text 'Pick a Radio' --column 'radio' --column 'url' --print-column 2 $(curl -s http://www.di.fm/ | awk -F '"' '/href="http:.*\.pls.*96k/ {print $2}' | sort | awk -F '/|\.' '{print $(NF-1) " " $0}') | xargs mplayer This command line parses the html returned from http://di.fm and display all radio stations in a nice graphical menu. After the radio is chosen, the url is passed to mplayer so the music can start dependencies: - x11 with gtk environment - zenity: simple app for displaying gtk menus (sudo apt-get install zenity on ubuntu) - mplayer: simple audio player (sudo apt-get install mplayer on ubuntu)

Shows you how many hours of avi video you have.

midentify.sh is part of mplayer, but you might have to locate it on your box.

Grep by paragraph instead of by line.

This is a command that I find myself using all the time. It works like regular grep, but returns the paragraph containing the search pattern instead of just the line. It operates on files or standard input. $ grepp or $ | grepp
