Overview

  Usage: vnl-tail [options] logfile logfile logfile ... < logfile

This tool runs "tail" on given vnlog files in various ways. "vnl-tail" is a wrapper around the GNU coreutils "tail" tool. Since this is a wrapper, most commandline options and behaviors of the "tail" tool are present; consult the tail(1) manpage for detail. The differences from GNU coreutils "tail" are

•: The input and output to this tool are vnlog files, complete with a legend

•: "-c" is not supported because vnlog really doesn't want to break up lines

•: "--zero-terminated" is not supported because vnlog assumes newline-separated records

•: By default we call the "tail" tool to do the actual work. If the underlying tool has a different name or lives in an odd path, this can be specified by passing "--vnl-tool TOOL"

Past that, everything "tail" does is supported, so see that man page for detailed documentation.

Compatibility

I use GNU/Linux-based systems exclusively, but everything has been tested functional on FreeBSD and OSX in addition to Debian, Ubuntu and CentOS. I can imagine there's something I missed when testing on non-Linux systems, so please let me know if you find any issues.
