sort Ref sɣur Libor Benes

sort Ref is a lightweight Firefox sidebar extension providing efficient offline access to 107 essential sort command options, field keys, flags, and practical usage scenarios. Designed as a rapid reference tool for the powerful text sorting utility, it's ideal for data organization, log processing, file merging, and shell scripting workflows.

The sort command originated in early Unix systems as a fundamental text processing tool. A sort command was first implemented within Multics. Later, it appeared in Version 1 Unix. This version was originally written by Ken Thompson at AT&T Bell Laboratories in November 1971.

sort, a fundamental Unix utility, organizes lines of text files in specified orders. Its ability to sort by multiple fields, handle various data types (numeric, human-readable, version numbers), and merge pre-sorted files makes it indispensable for system administration and data processing tasks.

sort Ref continues the Unix tradition of powerful, focused text processing tools by providing immediate access to sort's extensive capabilities without leaving the browser environment. The extension embodies the Unix philosophy of doing one thing well: providing sort reference information efficiently and securely.

Perfect for rapid reference while organizing data, processing logs, merging files, or preparing datasets in shell scripts. sort Ref delivers immediate value with emphasis on user security and system performance.
