I have a directory for certain purpose. Whenever i save a file
to that directory, I need to run a program upon the saved file.
My question is, Can the saving-file event intrigue the invocation
of my program AUTOMATICALLY? If can, how?
thanks!!! | y***y

can do anything.
are you manually saving or via some program?

after the file saved, then trigue another program?
if so, one simple way:
1) check the file's size, if it changes, then
run ur program
else do nothing
2) go to 1. :)
like ur mail notifier

发帖数: 36 | 4 What I want to do is like this:
1)I go to www.spaceflightnow.com
2)I download the daily news with the default name index.html
into that directory, using "save as"
Since this page has a very unsatisfying appearance, I wrote a perl
program to extract the text body from index.html to rearrange into
a new html file.
3)go to an xterm, to run the perl program.
Now I want the system to do the third step, so that I don't need to
shift to another window and type in the command---you know, sometim

发帖数: 36 | 6 Thanks,
but my situation is a little bit different. I need to surf
the web before I decide which news to download. When I click on
the link to that news, the address showed is not index.html,
but another unpredictable name. When I try to save-as, the
default name appearing in the dialogue box is index.html

caused by such a script?
I would rather to use crontab,

Yes, I have. The answer is: trivial.
Just like that you feel nothing when you invoke xbiff etc.
Please make an investigation about the CPU burden yourself.
Well, you can use whatever you want.
