Linux practice - regularly delete files under the directory
Since we want to delete the files under the directory regularly, we need to use the Linux crontab command. And the content format of each work routine is also introduced in the format of each crontab work.
Similarly, we need to use shell script to implement the function of deleting files. The function is relatively simple. Here we delete the files under the /tmp directory
Create and edit the del.sh script file
#!/bin/bash
dir=/tmp
files=`ls ${dir}`
for file in $files
do
if [ -e ${dir}/${file} ];then
rm -f ${dir}/${file}
fi
done
Then we start to use the crontab command to set the time. Here we set it to clear the files in the /tmp directory at 23:59 every night.
# crontab –e
Running the above command will bring up a vim editing interface, and we will add the following content
59 23 * * * /shell/del.sh
Save and exit. The work routine has been started. Execute the script at 23:59 every night to clear the files in the /tmp directory.
