How can I check the remaining disk quota?

Solution 1:

Take a look at the quota command here:

http://linux.die.net/man/1/quota

---

quota

For example:

quota -u user1

System response:

Disk quotas for user user1 (uid 501):
     Filesystem  blocks   quota   limit   grace files   quota   limit  grace    
     /dev/hda6     992   50000   55000              71   10000   11000

quota report

Report on all users over quota limits:

quota -q

Quota summary report:

repquota -a

bin       --   15644       0       0            101     0     0
...
user1     --    1944       0       0            120     0     0    

No limits shown with this user as limits are set to 0.

Solution 2:

If quotas are set, "quota" command shows the details.

quota -v
