Hello, how can I prefix every line of output of some command with a timestamp? I thought like this:
$ exec 3> >(while read line; do echo "$(date): $line"; done) $ seq 4 >&3 Friday, December 4, 2009 4:20:29 PM MET: 1 $ Friday, December 4, 2009 4:20:29 PM MET: 2 Friday, December 4, 2009 4:20:29 PM MET: 3 Friday, December 4, 2009 4:20:29 PM MET: 4 please note that the prompt ($) returns before the command completes. Why is the process substitution asynchronous? Does anybody know of a better way to accomplish this? Thanks, Peter
