[SOLVED]need help piping the output from an app... uh, yeah...
Ok, so there is a perl script that runs as a server, on my local host. It tells me which port to use. I want to pipe that output into my browser so I can do the whole thing with a single command. The problem is, I think, that the program doesn't actually exit cause it's running a server, so... so I dunno. Anyway the output looks like this:
... though obviously the port can be different. so, when I run 'foo.pl|grep http,' I just get the line with address, which is exactly what I want. I've tried a few things to get my browser to open this. So, at first I was trying this:
This doesn't work. It seems to start the server, but I don't get any output out of, so it's useless unless I check my ports manually. The browser doesn't start either. Then I tried this; cutting out the middle-man, as it were:
This starts the sever and the browser, but it doesn't actually point the browser at the server. not really sure what to try next. edit: bb is on the fritz right now or something. Formatting is really messed up

The problem is that the perl script doesn't exit (it maintians the server), so my bash script doesn't make it past that line. I tried it with an '&' but it breaks the syntax
And yes, firefox can be opened from the command line with a url (and I'm actually using uzbl-browser, but I didn't want it to throw anyone off).
so, you mean to say, the foo.pl will never exit but displays the info on the screen?
If that is the case, then why not write the ouput to a file and then read the file & open the browser. Something like this
I tried something similar earlier, but I had the grep before the '>,' which must have broken it.
This worked... well, it almost worked. It needs a moment for the output to be there from te browser, so I ended up with this:
... and then a little something to kill the perl script when the browser closes.

Hi all. I am using procmail to deliver an email to a script I am developing. Procmail delivers the email to the script on standard input. I imagine this is the same as piping input from a command into the script. Hence I've been testing my script by running

Not sure why this does not work in bash:
tail -f err.log |&
-bash: syntax error near unexpected token `&'
I am attempting to continuously read a file that is being updated by doing a "tail -f" on the file and piping the output to stdin which can then be read by the next shell command

Hi,
I was wondering why ls * | echo does not print the contents of the directory to the screen? The way I see it, ls * returns a whole lot of information, and then we pipe all this info to echo, so surely it should all come to our screen!
Is there a serious flaw in my understanding?
