Check These Out

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

Remove a range of lines from a file

Show one line summaries of all DEB packages installed on Ubuntu based on pattern search
I sometimes want to know what packages are installed on my Ubuntu system. I still haven't figured out how to use aptitude effectively, so this is the next best thing. This allows finding by name. The grep '^ii' limits the display to only installed packages. If this is not specified, then it includes listing of non-installed packages as well.

Show current working directory of a process

Synchronize date and time with a server over ssh
using -u is better for standardizing date output and timezones, for servers in different timezones.

Remove all unused kernels with apt-get
TIMTOWTDI

Rename all .jpeg and .JPG files to have .jpg extension
the "i" controls case sensitiveness. It's slightly inefficient since it uselessly renames .jpg to .jpg, but that's more than compensated by launching only one process instead of two, besides being shorter to write.

Remove a range of lines from a file
Deletes lines from START to END, inclusive. For example +4,10d will delete line 4, 5, ..., 10. Just like the vi command :4,10d does it.

Terminate a frozen SSH-session
A key sequence for terminating a frozen session. Full sequence on a swedish keyboard: [ENTER] [ALTGR] tilde [SPACE] dot

Simulate typing
this also generates errors (change 4 to higher number for more mistakes)
