UwView

UwView is a viewer and search tool for huge text and log files, with a GUI
and a command line (uvf) that share one engine.

• Open a file and scroll to the end at once. The file is never loaded into

memory; only the visible lines are drawn. Verified up to 258 GB /
4.5 billion lines in a single file.

• uvf searches many files in one run, plain text and seven compressed

formats mixed (gz, bz2, xz, lzma, zst, lz4, br), with no external
commands. Add -open and the hits appear in the window as
file-number:line; double-click to read around a hit.

• Encoding auto-detection (UTF-8, Shift_JIS, EUC-JP, UTF-16), bookmarks

remembered per file, keyboard shortcuts, real-time tail.

Run the command as uwview.uvf (or set sudo snap alias uwview.uvf uvf).
The snap reads files in your home folder. For removable media (/media,
/mnt), run sudo snap connect uwview:removable-media. Files elsewhere,
such as /var/log, are not reachable from the snap; copy them under your
home folder first.
