Cronjob question

jungsonn · 03-22-2003, 07:51 PM

Hy there.

I have a cronjob question,

i have my own server.

and i want to make a cronjob that runs every hour to check
an index.html, if a piece of <javascript> code is present in the source.
If the javascript code isn't there, i would like to receive an email about it.

Well, thats it and i'm a super newbee, so any help would be greatly apreciated...!

Ecuse me if i ask to much, but i have realy no clue howto do such a thing... thanks in advance.

Ronald.

hmm...does this javasrcript code have some unique text?

if so a simple search pattern should do the job (perl, grep, etc.), combined with your mailer (which would be), and crontab.
for crontab, see:
man 1 crontab (crontab -e to edit, etc.)
man 5 crontab (how to write the crontab entry)

PS. most likely you want the search/mailer in a bash/perl script (with error checking) and then just invoke the script with crontab.

Hope this was not to vague, I guess you could post back with more specific problems.

Let me explain the peoblem i encounter.

*I want to give away free hosting for a group of webmasters.
*The're webspace have ftp acces
*Every site, with there index MUST contain a bannercode.
*Like geocties that autoinclude a bannerscript.
*I am affriad they will remove my bannercode.
* so i like to do a checkup, if the code exist intheir index.html

This is because i do not know how to parse every uploaded html file, with my banner code... via ftp.
do you get it? ;-)
The ideal situation was this:

When they upload there index.html, there would be added a javascript bannercode into there index.html, automaticly.
but how?

i do not know

most likely sed. Sorry, but I don't know it well enough myself.

and you're right about the 'ideal' part: there are too many ways to get around the searching method, it will get to complicated. What you're looking for is a program that will find a line of code (eg. <body>) and append your text to it.
