grep is a command-line utility for searching plain-text data sets for lines matching a regular expression.

A user-friendly, faster, more capable grep replacement. Includes a TUI, Google-like Boolean search with AND/OR/NOT, fuzzy search, hexdumps, searches (nested) archives (zip, 7z, tar, pax, cpio), compressed files (gz, Z, bz2, lzma, xz, lz4, zstd, brotli), pdfs, docs, and...

All log file contents are merged into a single view based on message timestamps. You no longer need to manually correlate timestamps across multiple windows or figure out the order in which to view rotated log files.

TUI for viewing logs from journald, auditd, file system, Docker and Podman containers, Compose stacks and Kubernetes pods with supports log highlighting and several filtering modes.
