View the newest xkcd comic.

This function displays the latest comic from xkcd.com. One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic. To get a random xkcd comic, I also use the following: $xkcdrandom(){ wget -qO- dynamic.xkcd.com/comic/random|tee >(feh $(grep -Po '(?

generate iso

Copy all files. All normal files, all hidden files and all files starting with - (minus).

./* is for copying files starting with - .[!.]* is for copying hidden files and avoiding copying files from the parent directory. ..?* is for copying files starting with .. (avoids the directory ..) /path/to/dir the path to the directory where the files should be copied Can also be used as a script. Input argument is /path/to/dir in tcsh, replace .[!.]* with .[^.]*

Convert .flv to .avi

send substituted text to a command without echo, pipe

Measures download speed on eth0

list block devices

Shows all block devices in a tree with descruptions of what they are.

open a seperate konsole tab and ssh to each of N servers (konsole 4.2+)

creates a new tab for each of N servers in listofservers.txt and ssh's to said servers then, try the "send to all sessions" feature of konsole to do the same work on all servers at the same time. BIG time saver, but be careful!

Create a new file
