How to clear RAM Memory Cache, Buffer and Swap Space on Linux
Clear page cache only
# sync; echo 1 > /proc/sys/vm/drop_caches
Clear dentries and inodes
# sync; echo 2 > /proc/sys/vm/drop_caches
Clear page cache, dentries, and inodes
# sync; echo 3 > /proc/sys/vm/drop_caches
Now we will be creating a shell script to auto clear RAM cache daily at 3 am via a cron scheduler task.
Create a shell script
clearcache.sh and add the following lines.
#!/bin/bash # Note, we are using "echo 3", but it is not recommended in production instead use "echo 1" echo "echo 3 > /proc/sys/vm/drop_caches"
Change the permission on the
clearcache.sh using the below command
chmod 755 clearcache.sh
Next, open crontab for editing
Add the below line, save and exit to run it at 3 am daily.
0 3 * * * /path/to/clearcache.sh
List the crontab and verify using the below command
