Implement disk quota (note: Create/home partition when installing LINUX)
Objective: to implement a disk quota of 5 kB for soft limit and 10 kB for zhao in the/home directory.
Steps:
1. modify the line containing/home, # vi/etc/fstab, and change it to defaults and usrquota. That is, the usrquota item is added. Save and exit.
2. uninstall the/home directory # umount/home
3. mount/home directory # mount/home
4. Add user maid # useradd
5. change the password # passwd Todd
6. generate quota information about the/home directory # quotacheck-cmug/home
# Quotacheck-vu/home
7. View information of all users
