The 'mv' command is used in UNIX and UNIX-like systems to "move" a file from one location on the hard drive to another.
When "mv" is used as an abbreviation for "megavolt" (1,000,000 volts) it should be capitalized as "MV". For millivolt (0.001 volts) it's "mV".
On the Internet, mv is the top-level domain for Maldives.
Wordnet describes the Mv element (mendelevium) as:
a radioactive transuranic element synthesized by bombarding einsteinium with alpha particles.
But Jay Kominek's database of information related to the elements says mendelivium (atomic number 101) has "Md" as its symbol. Help?
Sheesh. All this blabber on two letters... forgive me. |
