History
In Unix, aliases were introduced in the C shell and thus survive in descendent shells such as tcsh and bash. C shell aliases were strictly limited to one line in a shell language where all complex constructs required more, but still useful for creating simple shortcut commands. Aliases were absent from the Bourne shell, which had the more powerful facility of functions. The alias concept was imported into Bourne Again Shell (bash) and the Korn shell (ksh). Shells such as these, that support both functions and aliases, recommend using functions where possible. Cases where aliases are necessary include the use of chained aliases (bash and ksh).

Famous quotes containing the word history:
“Racism is an ism to which everyone in the world today is exposed; for or against, we must take sides. And the history of the future will differ according to the decision which we make.”
—Ruth Benedict (1887–1948)
“The history of all Magazines shows plainly that those which have attained celebrity were indebted for it to articles similar in natureto Berenice—although, I grant you, far superior in style and execution. I say similar in nature. You ask me in what does this nature consist? In the ludicrous heightened into the grotesque: the fearful coloured into the horrible: the witty exaggerated into the burlesque: the singular wrought out into the strange and mystical.”
—Edgar Allan Poe (1809–1849)
“If man is reduced to being nothing but a character in history, he has no other choice but to subside into the sound and fury of a completely irrational history or to endow history with the form of human reason.”
—Albert Camus (1913–1960)
