Usage
The Bourne shell was once standard on all branded Unix systems, although historically BSD-based systems had many scripts written in csh. Bourne shell scripts can typically be run with bash or dash on GNU/Linux or other Unix-like systems.
On many Linux systems, /bin/sh is a symbolic or hard link to Bash. However, for efficiency, some Linux systems (such as Ubuntu) link /bin/sh to dash instead.

Famous quotes containing the word usage:
“...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
—Kenneth G. Wilson (b. 1923)
“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
