How can I log to a specific file in linux using logger command?

Question

I will run the following script:

#!/bin/bash
./myprogram

#get exit code
exitvalue=$?

#log exit code value to /var/log/messages
logger -s \"exit code of my prog         


        

Answer 1

If you want to use logger so that the message appears both in the system logs and in some file of yours, you might do

  logger -s your message 2> $HOME/somefile

since the -s option to logger also outputs on stderr which is redirected to the file with 2>

You could want to use 2>> $HOME/somefile to append (not overwrite) your $HOME/somefile (read about bash redirections), and (see logger(1) for details) you may prefer to pass the program option --id=$$ to logger.
