Hi everyone,
I copied a program from C to track multiple log files. I would like to be
able to print a label when a log file is updated. Here is the program;
Since you're calling tail itself, why not just use tail's ability to
tail multiple files? It too will output the label.
I am using tail from the GNU coreutils, version 5.97.
I did the following, using two xterms:
First, in one xterm window:
$ touch foo bar
$ tail -f foo bar
Then in another xterm:
$ echo "Hi foo" > foo
$ echo "Hi bar" > bar
Back in the first xterm window I see this:
$ tail -f foo bar
==> foo <==
==> bar <==
==> foo <==
Hi foo
==> bar <==
Hi bar
Thanks Joe, sure am glad I asked. Oh well it was good practice as I am
just learning python, I don't know how I missed that I could tail more
than one file.
