One-liner Program
A one-liner is textual input to the command-line of an operating system shell that performs some function in just one line of input.
The one liner can be
- An expression written in the language of the shell.
- The invocation of an interpreter together with program source for the interpreter to run.
- The invocation of a compiler together with source to compile and instructions for executing the compiled program.
Certain dynamic scripting languages such as AWK, sed, and Perl have traditionally been adept at expressing one-liners. Specialist shell interpreters such as these Unix shells or the Windows PowerShell, allow for the construction of powerful one-liners.
The use of the phrase one-liner has been widened to also include program-source for any language that does something useful in one line.
Famous quotes containing the word program:
“The discovery of Pennsylvania’s coal and iron was the deathblow to Allaire. The works were moved to Pennsylvania so hurriedly that for years pianos and the larger pieces of furniture stood in the deserted houses.”
—For the State of New Jersey, U.S. public relief program (1935-1943)
