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.

Google text-to-speech in mp3 format

Usage: t2s 'How are you?' Nice because it automatically names the mp3 file up to 15 characters Modified (uses bash manip instead of tr) t2s() { wget -q -U Mozilla -O $(cut -b 1-15

kills rapidly spawning processes that spawn faster than you can repeat the killall command

if you dont want to alias also then you can do killall rapidly_spawning_process ; !! ; !! ; !!

Quick glance at who's been using your system recently

This command takes the output of the 'last' command, removes empty lines, gets just the first field ($USERNAME), sort the $USERNAMES in reverse order and then gives a summary count of unique matches.

open path with your default GNOME program

Another step to bring cli and gui closer together: gnome-open It opens a path with the default (gui) application for its mime type. I would recommend a shorter alias like alias o=gnome-open More examples: $ gnome-open . [opens the current folder in nautilus / your default file browser] $ gnome-open some.pdf [opens some.pdf in evince / your default pdf viewer] $ gnome-open trash:// [opens the trash with nautilus] $ gnome-open http://www.commandlinefu.com [opens commandlinefu in your default webbrowser]

Hide or show Desktop Icons on MacOS

Hides all Files and Folders on the MacOS Desktop. To show files and folders, type "true" instead of "false". "Finder" at the end is case sensitive, "finder" doesn’t work

Calculate days on which Friday the 13th occurs (inspired from the work of the user justsomeguy)

Friday is the 5th day of the week, monday is the 1st. Output may be affected by locale.

Video thumbnail

Faster thumbnail creation than '-itsoffset' $ffmpeg -itsoffset -4 -i test.avi -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 test.jpg

do a full file listing of every file found with locate

Show top 50 running processes ordered by highest memory/cpu usage refreshing every 1s

http://alvinalexander.com/linux/unix-linux-process-memory-sort-ps-command-cpu for an overview of --sort available values

Verify MD5SUMS but only print failures

All valid files are withheld so only failures show up. No output, all checks good.
