grep Ref geliştiren: Libor Benes

grep Ref is a lightweight Firefox sidebar extension providing efficient offline access to 89 essential grep commands, flags, pattern examples, and practical usage scenarios. Designed as a rapid reference for the powerful text search utility

grep (globally search a regular expression and print) was created by Ken Thompson in 1973 as part of early Unix development at Bell Labs. It emerged from the ed editor's search functionality (g/re/p command) and became one of the most fundamental Unix utilities, influencing countless text processing tools that followed.

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

Perfect for rapid reference while crafting complex search patterns, filtering logs, extracting data, or debugging text processing pipelines in shell scripts. grep Ref delivers immediate value with emphasis on user security and system performance.
