cut Ref nga Libor Benes

cut Ref is a lightweight Firefox sidebar extension offering efficient offline access to 107 essential cut command options, field specifications, delimiter patterns, and practical usage scenarios.

The cut command, written by Gottfried W. R. Luderer at Bell Labs in February 1985, originated as a Unix text processing tool for extracting columns and character ranges. It excels at simple column extraction where full regex power isn't required, offering superior performance and simplicity compared to tools like awk for straightforward operations. cut's design embodies the Unix philosophy of creating focused, composable tools.
