I have a script that uses backticks to run commands, capture the output and
append it to a file. Someone requested that the script also output
immediately to the screen. we are having troubles with some commands
hanging, amd we want to know where the hang is. so if we could see the last
output, we would know.
Is there an easy way to tweak backticks so it still captures the output but
also tees the output to stdout?
also, the command that is hanging, I set an ALRM that has 'die' as its
callback. but I end up with the backtick command.running as a zombie
process. I have no idea why its doing that. but I dont think I have ever
used ALRM either.
