Taken from apticron and modified.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.
Ssh to host1, host2, and host3, executing on each host and saving the output in {host}.log.
I don't have the 'parallel' command installed, otherwise it sounds interesting and less cryptic.

numsum is part of of the num-utils package, which is available in some Linux distros and can also be downloaded at http://suso.suso.org/xulu/Num-utils. It contains about 10 different programs for dealing with numbers from the command line.
Obviously you can do a lot of things that the num-utils programs do in awk, sed, bash, perl scripts, but num-utils are there so that you don't have to remember the syntax for more complex operations and can just think: compute the sum, average, boundary numbers, etc.
For example, you need to make a copy of all the libraries that a certain application uses, with this command you can list and copy them.
Returns logs between HH:M[Mx-My], for example, between 13:40 and 13:45.
Using this command you can track a moment when usb device was attached.
