bash-3.2$ df -h Filesystem size used avail capacity Mounted on 132G 80G 50G 62% / /devices 0K 0K 0K 0% /devices ctfs 0K 0K 0K 0% /system/contract proc 0K 0K 0K 0% /proc mnttab 0K 0K 0K 0% /etc/mnttab swap 418G 488K 418G 1% /etc/svc/volatile swap 418G 38M 418G 1% /tmp swap 418G 152K 418G 1% /var/run /dev/dsk/c20t60000970000192602156533030374242d0s0 236G 240M 234G 1% /peterdata/cm_new /dev/dsk/c20t60000970000192602156533032353441d0s0 30G 30M 29G 1% /peterdata/native ...
