central-logger

central-logger is a file watcher which detects only the keywords list changes in a file and logs them into a more dedicated destination file.

Shell arguments

-f : filename somefile.txt. Required -k : keyword list to watch for. e.g. 'error|csrf|down'. Required -o : output file. default output.log -v 1: verbous mode. default none-verbous -b 1: run process in background and return shell. default foreground

first time you run the script, make sure it has rwx permissions

chmod 777 central-logger.sh

then whenever you want to watch a file, just do as below.

bash ./central-logger -f hosts -k 'error|broke|warning|kill' -o vital-logs.log -v 1 -b 1

example above watches the file hosts for any entries defined in the passed keyword_list (-k 'error|broke|warning|kill') and then logs them to the output file vital-logs.log

cat vital-logs
