My fave for running and monitoring scripts is GNU screen.<br>
With it you can just run the script in screen sessions and attach to
it when you want to see the status (or debug) your script. <br>
<br>
screen -S foo<br>
screen -r foo <br>
/path/to/script.sh<br>
CTRL-a d #detach from session<br>
<br>
Far easier than debugging log files!<br>
<br>
When I want to run a number of scripts or use cron to kick them off,
I write a wrapper script which creates a screen session and injects
the commands for example:<br>
<br>
screen -dm foo<br>
sleep 5 #just gives the command time to execute<br>
screen -X -S foo -p0 eval 'stuff /path/to/script.sh'<br>
sleep 5<br>
screen -X -S foo -p0 eval 'stuff \015' #return key equivalent<br>
<br>
Any screen can then be recovered to current terminal with <br>
<br>
screen -r foo #if the screen is currently not attached to any
terminal<br>
<br>
or <br>
<br>
screen -x foo #if it is already attached to a terminal<br>
<br>
to detach from the screen session use: <br>
<br>
CTRL-a d <br>
<br>

<pre wrap="">Hi, I recently had an issue where I wanted to ge some visibility on what
some large script which included various tasks, functions, sub scripts
etc... were doing.
Mostly I wanted another way to view where a script was, what it was doing
while it was still running. While the scripts do produce log files I wanted
to view a snapshot of this point in time.
ps does contain all this data but managing it is sometimes a little
difficult, passing the filters to get the granularity you require and
getting the formatting needed wasn't easy.
So I created a pair of bash functions that I can include in a text file,
then pull them into the command line and call them whenever I wanted an
overview of my scripts.
I have put the code on my wiki, hope this might be of use to someone else:

I just have to include the functions on the command line as:
. /path/to/script.sh
then call the main function to get all shell scripts and output their
details:
dh_script_view
This should be fairly easy to understand and modify for viewing sub
processes of any process you chose handing it's pid to the function:
dh_pidtree
