/vol/mc3240a/            190GB       18GB      171GB      10%  /vol/mc3240a/

/vol/mc3240a/.snapshot       10GB      355MB     9884MB       3%  /vol/mc3240a/.snapshot

/vol/mc3240b_root_backup/      210GB     9019MB      201GB       4%  /vol/mc3240b_root_backup/

df -h | egrep "(8[5-9]|9[0-9]|100)%" | cut -f 1 -d " "

This will catch 85% up to 100% (the 0, does the {1}00%)

The cut will show the 1st column (anything after the 1st space in the output is deleted; a device can not have a space)

Examples:

Filesystem            Size  Used Avail Use% Mounted on

/dev/sda1             139G  132G  218M 100% /

varrun                2.0G  368K  2.0G   1% /var/run

varlock               2.0G     0  2.0G   0% /var/lock

udev                  2.0G   48K  2.0G   1% /dev

devshm                2.0G     0  2.0G   0% /dev/shm



$ df -h | egrep "(8[5-9]|9[0-9]|100)%" | cut -f 1 -d " "

/dev/sda1



Filesystem            Size  Used Avail Use% Mounted on

/dev/sda1             144G  130G  7.5G  95% /

varrun                506M  148K  506M   1% /var/run

varlock               506M  4.0K  506M   1% /var/lock

udev                  506M   72K  506M   1% /dev

devshm                506M     0  506M   0% /dev/shm

$ df -h | egrep "(8[5-9]|9[0-9]|100)%" | cut -f 1 -d " "

/dev/sda1
