Several ways to perform tasks per second in Linux crontab

The first method:

1. Create a script file

The code is as follows	Copy Code
Cat phplog.sh 2. Edit Script Content #!/bin/bash While:;d o /home/scripts.sh 2>/dev/null & Sleep 1 Done

Note: Do not use bash phplog.sh & the way the background runs this first time, it will be zombie.
Workaround: You can put it on a scheduled task to run it, and then delete this entry from the scheduled task. Finally, put the script in/etc/rc.local so that it can be run every time it is powered on.

The second method:

The code is as follows	Copy Code
1. Create a script file Cat phplog.sh 2. Edit Script Content #!/bin/bash For ((i=1;i<=20;i++));d o /home/scripts.sh 2>/dev/null & Sleep 1 Done 3. Edit Crontab Script * * * * */bin/bash/home/somedir/phplog.sh * * *

The third method:

1. Edit Crontab Script

The code is as follows	Copy Code
* * * * */home/scripts.sh * * * * * * * * * Sleep 1 &&/home/scripts.sh * * * * * * Sleep 2 &&/home/scripts.sh * * * * * * Sleep 3 &&/home/scripts.sh ... * * * * * * sleep &&/home/scripts.sh * * * * * sleep &&/home/scripts.sh * * * * * sleep &&/home/scripts.sh

Finally, a third method is recommended.
