ttyrpld - TTY replay daemon

ttyrpld [rusty colors]

Name > ttyreplay - realtime log file player

Synopsis >

ttyreplay [-F|-f] [-S factor] [-T] [-?|--help]

Description >

ttyreplay is the tool to see -- to replay -- what has been captured by (the Kernel module and) rpld. Give it any number of files you want to see again. Options apply to all files.

Options >

-F	Live feed follow mode. Seek to the end of the file and tail-follow any new contents that are written to it. This does the same as ``tail -f`` does with normal text logfiles.
-S factor	Plays the file back with a time warp of factor. `1.0` is normal time, `2.0` is twice as fast, `0.5` half speed, etc.
-T	Shows (replays) the log without any delays. This can be used to generate a screen log like `script` or `screen` (rpl logfile without any packet headers, basically) for easy grepping.
-f	Catch-up follow mode. Plays the file back from the start as usual and switches into -F mode when EOF is reached.

Example files >

There is an example file I provided, you can watch it with bzip2 -cd Commenting_ovcorr.bz2 | ttyreplay /dev/stdin. It shows 1:1 (and in full color!) how I commented the nsleep_ovcorr() function. It is advisable to run it with speed factor 3.0 (-S option), because in real-time, it takes approximately 35 minutes.
