Find the package that installed a command

Reset hosed terminal,
stty sane resets the tty to basic usable function. The ^J is a newline -- sometimes CR/LF interpretation is broken so use the ^J explicitly.

Convert mysql database from latin1 to utf8
MySQL: CHARSET from latin1 to utf8

encode HTML entities
Encodes HTML entities from input (file or stdin) so it's possible to directly past the result to a blog or HTML source file.

Manipulate the metadata when the photo was taken, this will shift with +15hours + 30min

Shows space used by each directory of the root filesystem excluding mountpoints/external filesystems (and sort the output)
Useful to see at glance which directory under the root file is using most space

ssh and attach to a screen in one line.
If you know the benefits of screen, then this might come in handy for you. Instead of ssh'ing into a machine and then running a screen command, this can all be done on one line instead. Just have the person on the machine your ssh'ing into run something like $ screen -S debug Then you would run $ ssh -t [email protected] screen -x debug and be attached to the same screen session.

find all executable files across the entire tree
I can think of using this command after compiling an downloaded source from anywhere as an easy way to find all executable products. We usually issue the $ find command (without arguments) to list the full paths of all directories and sub-directories and files in the entire current tree. Similar command is $ tree -aicfnF

Rename files in batch

Show a git log with offsets relative to HEAD
Print a git log (in reverse order) giving a reference relative to HEAD. HEAD (the current revision) can also be referred to as HEAD~0 The previous revision is HEAD~1 then HEAD~2 etc. . Add line numbers to the git output, starting at zero: $ ... | nl -v0 | ... . Insert the string 'HEAD~' before the number using sed: $ ... | sed 's/^ \+/&HEAD~/' . Thanks to bartonski for the idea :-)
