Cron to delete files
| Posted by biggerboy, 06-15-2008, 08:45 PM |
| I want to setup a crontab to delete a file every 24 hours, I am not the best in crontab so was wondering if one of you could please give me the command I should use?
Thanks,
Alex

| Well one way you could do it is make a shell script that would delete the file, and then setup that shell script in your cron tab.

| Alright that would work, what should I put into the script?

| the shell script ----------
#!/bin/bash
# Remove Files
rm -f /location/of/file/myfile.txt
------------------------
------ the cron job -------------
30 16 * * * ./mycommand/script > /dev/null
------------------------
Where
30 16 = 4:30PM (16 is military time hour) (30 is the minute) (set these to the time you want it to run)
./mycommand/script = the shell script file you created that will be ran

| I'd actually use a perl script. Perl makes handling errors a lot easier. The only reason I mention this is because automating deletion of files can be dangerous.
You can copy the script up above into a file, and move that file into /etc/cron.daily that way you don't have to maintain crontab.

| If you don't mind me asking, what produces the file you need to delete every 24 hours?
