How to use Shell for file monitoring, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

(can be used for automatic code publishing)

Inotify is a feature of the linux kernel and can be used above kernel 2.6.13.

Monitor / usr/local/src directory:

/ usr/local/bin/inotifywait-mrq-- timefmt'% d/%m/%y% HGV% M'-- format'% T% w% f% e'-e modify,delete,create,attrib / usr/local/src

Parameters:

-m continuous monitoring

-r Monitoring directories using recursion

-Q reduce redundant information and print only the information you need

-e specifies the events to be monitored, separated by commas

-timefmt time format

-Information on file changes monitored by format

-timefmt description:

Ymd stands for year, month and day, H for hours and M for minutes.

-format description:

After executing the above command, create a 1.txt file under the listening directory and get the following result:

22-03-18 17:22 / usr/local/src/ 1.txt CREATE 22-03-18 17:22 / usr/local/src/ 1.txt ATTRIB

The function of this script is to cycle to listen for the addition, deletion and modification of a file or directory, and to execute the set script file when the event occurs.

#! / bin/sh # Monitoring files or directories filename=$1 # Monitoring scripts script=$2 inotifywait-mrq-- format'% e'-- event create,delete,modify $filename | while read event do case $event in MODIFY | CREATE | DELETE) bash $script;; esac done

Background execution of shell script

Nohup

Use nohup, where test.sh is the script being executed and out.txt is where the information is output.

Nohup sh test.sh > out.txt & after reading the above, have you mastered how to use Shell for file monitoring? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
