Here's a very simple and cheesy cgi progress bar:

Code:

#!/bin/bash

echo "Content-type: text/html"
echo
echo "<html><body><pre>Processing file:"

# Remember, you can't UN-print anything in HTML.  So it's either a very
# primitive progressbar like this, or printing entire javascript
# statements to update some fancy DHTML widget.
printf "Begin [[ "

for((N=0; N<5; N++))
do
        printf "."
        sleep 1
done

printf " ]] Done!\n</pre>\n";


cat <<EOF

<!--    URL can point to anything you want.  I just made it a data URL
        to keep the script completely self-contained.
        /etc/issue was just a handy textfile :D -->
<a id="dataurl" href="data:text/plain;base64,$(openssl base64 < /etc/issue)">Click Here Or Wait</a>
<!--    Javascript portion is necessary, since there's no other way to
        inform the web browser that you're sending a file after you've
        already started sending a webpage. -->
<script>
        // Send the user's browser to the URL.
        // Putting the openssl base64 ... junk in here doesn't work too well, since
        // javascript barfs on newlines in strings, but ordinary HTML tag attributes don't.
        e=document.getElementById("dataurl");
        window.location=e.href;
</script>
</body></html>
EOF

JBOSS process quits on shell exit

Exit() system call verses process signals

Hello and thanks in advance for any help anyone can offer me I've been reading up on process signal calls (sighup, sigint, sigkill & sigterm) and I understand they all have different methods of terminating a running process. From what I've also read is a exit() actually terminates a process. ...

LEARN ABOUT SUNOS

shell

shell(1F)							   FMLI Commands							 shell(1F)

NAME

       shell - run a command using shell

SYNOPSIS

       shell command [command] ...

DESCRIPTION

       The  shell  function  concatenate  its arguments, separating each by a space, and passes this string to the shell ($SHELL if set, otherwise
       /usr/bin/sh).

EXAMPLES

       Example 1: A sample output of shell command.

       Since the Form and Menu Language does not directly support background processing, the shell function can be used instead.

       `shell "build prog > /dev/null &"`

       If you want the user to continue to be able to interact with the application while the background job is running, the  output  of  an  exe-
       cutable	run  by shell in the background must be redirected: to a file if you want to save the output, or to /dev/null if you don't want to
       save it (or if there is no output), otherwise your application may appear to be hung until the background job finishes processing.

       shell can also be used to execute a command that has the same name as an FMLI built-in function.

NOTES

       The arguments to shell will be concatenate using spaces, which may or may not do what is expected. The variables set in local  environments
       will not be expanded by the shell because "local" means "local to the current process."
