Check out Gate number for your flight from CLI with Chrome

Check out Gate number for your flight from CLI with Chrome, html2texgt and grep. Works on Arch Linux (Garuda) and probably will work on others. Requirements: * google chrome (might work with chromium as well) * installed html2text (on archlinux: sudo pacman -S python-html2text) * installed grep (comes by default with your OS) * the gate number should be visible at the given website (it's not existent too early before the flight and also disappears after the flight departed) Please don't forget to replace the link to appropriate one, matching your flight. You can also wrap this into something like `whlie true; do ...; sleep 60; done' and this will check and tell you the gate number maximum in 1 minute after it appears on Avinor website.

quick and easy way of validating a date format of yyyy-mm-dd and returning a boolean

Quick and easy way of validating a date format of yyyy-mm-dd and returning a boolean, the regex can easily be upgraded to handle "in betweens" for mm dd or to validate other types of strings, ex. ip address. Boolean output could easily be piped into a condition for a more complete one-liner.

Recursively search a directory tree for all .php .inc .html .htm .css .js files for a certain string

easily find megabyte eating files or directories

Thanks for the submit! My alternative produces summaries only for directories. The original post additionally lists all files in the current directory. Sometimes the files, they just clutter up the output. Once the big directory is located, *then* worry about which file(s) are consuming so much space.

              sort -n | \

                printf(\"%4s MB  ./\",\$1); \
                for ( i=1 ; i<=NF ; i++ ) { \
                  if ( i > 1 ) printf(\"%s \",\$i) \
                }; \
                printf(\"\n\") \
              }' | \

Remove all the files except abc in the directory

Really, you deserve whatever happens if you have a whitespace character in a file name, but this has a small safety net. The truly paranoid will use '-i'.

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.

Git diff last two commits

How about this one ?

Change pidgin status

Thanks for the comment oshazard, i wasn't aware of purple-remote existence.

Get list of servers with a specific port open

Change the -p argument for the port number. See "man nmap" for different ways to specify address ranges.

clean up syntax and de-obfuscate perl script

the command show can be run in vim, here is the same thing on the command line $ cat script.pl | perl -MO=Deparse | perltidy

split and combine different pages from different pdf's

The command shows the real power of the pdftk tool, you can do basically everything you want with multiple pdf's. In the command a book is created from chapters, headings and covers.

Convert a mp3 file to m4a

I use this to convert mp3 files to m4a files that can be used as ringtones on the iPhone. I've documented the process here: http://www.control-d.com/?p=60

Remote execute command as sudoer via ssh

Example: remote install an application(wine). sshpass -p 'mypssword' ssh -t mysshloginname@192.168.1.22 "echo 'mypassword' | sudo -S apt-get install wine" Tested on Ubuntu.

Find the biggest files

Also: * find . -type f -exec ls -s {} \; | sort -n -r | head -5 * find . -type f -exec ls -l {} \; | awk '{print $5 "\t" $9}' | sort -n -r | head -5

List all directories only.

Undocumented syntax, but should work on every shell. It'll list all directories in the current one. Change `*/` into globbing `**/` for recursivity.

Kill all processes that listen to ports begin with 50 (50, 50x, 50xxx,...)

Run netstat as root (via sudo) to get the ID of the process listening on the desired socket. Use awk to 1) match the entry that is the listening socket, 2) matching the exact port (bounded by leading colon and end of column), 3) remove the trailing slash and process name from the last column, and finally 4) use the system(…) command to call kill to terminate the process. Two direct commands, netstat & awk, and one forked call to kill. This does kill the specific port instead of any port that starts with 50. I consider this to be safer.
