Questions tagged [cut]

A Unix shell command that breaks input into fields, which can be selected for output, based on a delimiter.

cut is often the easiest way to split input lines or to extract only parts from them. If the rule how to split a line into fields can be expressed with a single character, cut should be used insead of the more powerful tools sed or awk.

cut can select fixed ranges from the input line, be they bytes or characters.

The perfect match for cut is, of course, .

In scientific software for statistical computing and graphics, the function cut partitions elements of a numeric vector into bins.
