Download all images from a site
This recursively downloads all images from a given website to your /tmp directory. The -nH and -nd switches disable downloading of the directory structure.

move contents of the current directory to the parent directory, then remove current directory.
Robust means of moving all files up by a directory. Will handle dot files, filenames containing spaces, and filenames with almost any printable characters. Will not handle filenames containing a single-quote (but if you are moving those, it's time to go yell at whoever created them in the first place).

Prepend a text to a file.
Using the sed -i (inline), you can replace the beginning of the first line of a file without redirecting the output to a temporary location.

Display current time in requested time zones.
The time zone names come from the tz database which is usually found at /usr/share/zoneinfo.
