wcat [-w wtmp|-] [-adX[3|4]] [-s start] [-e end] [-b H[:M[:S]]] [--help] [--version]

Wcat provides an easy way to recover trimmed information from wtmp binary files. This tool can be useful for scripts that need only partial information from them.

Notice that wcat output is binary wtmp entries so if this information is printed out to a terminal or screen it might mess it up. A better use of wcat would be: wcat | rawtmp -w -

-w wtmp|-

-X[3]

-d

-e end

-b H:M:S
