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:
“Navajo men and boys have an odd way of showing their friendship. When two young men meet at the trading post, a “Sing”, or a dance they greet each other, inquire about the health of their respective families, then stand silently some ten or fifteen minutes while one feels the other’s arms, shoulders, and chest.”
