This article mainly introduces Linux how to realize the operation method of disk space occupied by timing files, which is very detailed and has certain reference value. Friends who are interested must finish reading it.

Open scheduled task editing. Cent is opened directly using vim by default. If ubutun installs multiple editors, the first time you open it is to specify the operation of the editor.

(3) * / 1 * sh / root/Shell/monitor.sh adds this line to the file. Indicates that the sh / root/Shell/monitor.sh command is executed every other minute, and more timing formats can be queried online. That's all it takes for simple loop monitoring.

(4) service crond start starts the scheduled task. It's service cron start on ubutun.

(5) check whether the crontab scheduled task has started crontab-l

(1) du-BM / root/Shell/a.pdf | awk'{print $1} 'gets the file size. -the BM result is M output, and for those that need G output, use-BG.

(2) cachesize=$ (du-BM / root/Shell/a.pdf | awk'{print $1}') uses the cachesiz variable to receive the file size. Note that what is received at this time is with units, such as 89m

(3) cachesize=$ (echo ${cachesize/M/}) removes M to get the pure number 3. Complete code
