Removal of wget generated files
Posted by ladless, 09-19-2008, 03:19 PM Hi there. I have several cronjobs set up like the following example: Obviously a bunch of files are being created in the /root folder. I believe I don't need those files. They all have incremental numbers as extensions. Nothing bad happens if I delete them by hand but after a while they are many and it's annoying. I understand there is a parameter for the wget command: wget --delete-after that deletes those files automatically. My question is if the following cronjobs will work in the new shape: Won't that conflict somehow with the name of the address of the site ? I also thought about using the following form: Which form would do the work ? I basically need to fetch an URL with wget silently. Thanks in advance.
Posted by Panopta, 09-19-2008, 03:31 PM Wget doesn't write the output of the file to stdout, so redirecting won't work. You need to use the -O option to change the file that is written, which can be set to /dev/null:
Posted by ladless, 09-19-2008, 03:50 PM Many thanks. I will try that in a minute. Hopefully it will work. Anyway I will get back with an answer, good or bad. Thanks again.

Posted by ladless, 09-20-2008, 02:17 PM It works. Thanks for your help guys. However yet I have one question: is there a limit for how many cron jobs a server can run ? Would it be ok to have let's say 200 cron jobs like the above ?
Posted by Harzem, 09-20-2008, 02:29 PM It's best not to have so many. Create single a script that will do all those jobs, and call that script with cron.
Posted by ladless, 09-20-2008, 02:52 PM Would a script like the following one have the same effect ? I mean would that work ? I basically need to execute those URL's somehow.

Posted by ladless, 09-20-2008, 03:17 PM How about the following variant. I will have a cron job to do this: Inside the script.sh I will have this: Would my example work ?
