watchlogs is a simple command line utility for watching multilpe log files and interleaving their contents to stdout as each log is appended to. It aims to achieve the functionality of tail -F, but with more colour.
watchlogs --log_files /path/to/log1.txt,/path/to/log2.txt,....
Install via pip install watchlogs. If you prefer to hack around with the source code, it's a single python file.
watchlogs has the following behaviour when log.txt is updated (assuming that watchlogs --log_files log.txt has been run):
-
action: appending (supported)
echo "x" >> log.txt(printsxto screen) -
action: moving/rotating (supported)
touch log2.txt ; echo "y" > log2.txt ; mv log2.txt log.txt(printsyto screen) -
action: overwritng in-place (not supported):
echo "z" > log.txt(zis lost)
watchlogs uses the tailf library to monitor OS events.
