I know of no way to make HTML run a bash script, but I'm hardly a guru.

Perhaps if you explain what end result or output you want, as opposed to one way you are trying to produce that end result, someone could help you.

errr...
i want to display my serial number using web browser. i have my php code that will ask user to put some name like example. and that name will be shown with serial number like this.

enter name:______

name : athrin.
serial: xxxxxx

the problem is the serial wont show. i already tried to do this code

Code:

dmidecode | grep Number > /var/www/cgi-bin/serial

by sending the serial to another file and in my bash will call the file by using "cat". but it still not showing, i want my serial to be shown. do you have any idea on how to do that?

you cannot run dmidecode by browser it will say permission denied .. If u already saved your serial number in a file u can always display it through webpage ..PHP can do it..The following code will work

Quote:

echo `cat /var/www/cgi-bin/serial`;

In the above quote note that to make your linux command work you have to use above command...
u can show your linux command in web-browser by

Quote:

echo `your linux command here`

hope this works for you

SO you want the output of a bash command to appear inside an HTML page?

How are you executing the command? Seems like doing it via PHP, Perl, Python, or another server-side scripting language would be the only way.

No almost every server side scripting language has inbuilt functions to make system calls..
PHP has two or three methods to do that ,one of them is above ...

I know that PHP isn't the only scripting language that can do it, I just said it that way since PHP was what the OP is using. I'll edit my post to clear up the confusion.

I think there is problem with permissions....dmidecode can run only by root or sudoers..

If so, you can make sudo run the dmidecode command for a certain user without asking for a password. Run visudo and add this line:

Code:

username ALL = NOPASSWD: path-to-dmidecode-executable

What about using a cron job that builds runs the dmidecode command and redirects it output into a file inside your webserver directory?

Seems like that way the page will not always be up to date.

Your probably right, I forget that the info of dmidecode changes so fast.
