  • aria2c to speedtest connection

    Tests connection speed over HTTP request. Can use a lot of http mirrors of SAME file (Useful for test with Ubuntu mirrors, as example) and the split will be done opening connections in all urls if possible. -s Split connections in N number MAX=16 -j Set max concurrent downloads, must be equal to -s or will be restricted to this number. -x Set max connection per server, recommended to be the same of split. -k Min Split Size, default is 20MB, usefull to really force more splited connections over same file -d Directory to save the "file", in this case, /dev -o Points output to null --file-allocation=none Do not attempt to prealocate the file. --allow-overwrite=true Overwrite to /dev/null. Recommend use "rm /dev/null.aria2" after if runned as root. Show Sample Output

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.

Check These Out

rsync + find
use find with rsync

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Read aloud a text file in Ubuntu (and other Unixes with espeak installed

Display a wave pattern
Purely frivolous - print a sine/cosine curve to the console - the width varies as it progresses. Ctrl-C to halt.

use xxd to create the wake on lan magicpacket and write to pcap file
just set macdst to the mac address of the system you wish to wake up, the macsrc is optional but helps use tcpreplay to broadcast or wireshark to view

Find usb device in realtime

Set OS X X11 to use installed Mathematica fonts

calulate established tcp connection of local machine

check the fucking weather
grab the weather, with a little expletive fun. replace the 48104 with a US zipcode, or the name of your city (such as ZIP="oslo"), unless you want to know what the weather is like for me (and that's fine too)

Content search.
Grep will read the contents of each file in PWD and will use the REs $1 $2 ... $n to match the contents. In case of match, grep will print the appropriate file, line number and the matching line. It's just easier to write $ ff word1 word2 word3 Instead of $ grep -rinE 'word1|word2|word3' .
