Let's take a look.

To delete all files in a directory regularly, you need to use linux's crontab command, which can be implemented with a shell script. For example, delete all cache files under / tmp as follows:

[root@localhost ~] # vi / etc/init.d/delete.sh press I and copy the following to the delete.sh file, then press shift+: and enter wq to save and exit. #! / bin/bashdir=/tmp / / the directory name files= `ls ${dir} `for file in $filesdoif [- e ${dir} / ${file}]; thenrm-f ${dir} / ${file} fidone

Then give the script 755 permissions with the following code:

[root@localhost ~] # chmod 755 / etc/init.d/delete.sh

Let's use the crontab command to set the time, for example, to clear all files in the / tmp directory at 3 a.m. Every day. Running the following command will enter the vim editing interface.

[root@localhost ~] # crontab-e paste the following code; 0 3 * / etc/init.d/delete.sh save and exit, now the scheduled work has been completed, and automatically empty the files in the / tmp directory at 3 am every morning. Time usage instructions for crontab-e * / etc/init.d/delete.sh timesharing, day, month, week, column 1, month, month, week, week, month, month, week, month, month, 0-6 (0 for Sunday) column 6 is the command to run, for example, run the script at 23:30 every Wednesday night, you can write: 30 23 * 3 / etc/init.d/delete.sh

The same is true for other periods of time.
