oops! it happened again... unix machine says, disc is full...more precisely
write: journal: No space left on device
No probelm, command df can save our life.
df shows how much free space is available in each mount.
It has a list of options, and the man page says like
| a, --all | include dummy file systems |
| -B, --block-size=SIZE | use SIZE-byte blocks |
| -h, --human-readable | print sizes in human readable format (e.g., 1K 234M 2G) |
| -H, --si | likewise, but use powers of 1000 not 1024 |
| -i, --inodes | list inode information instead of block usage |
| -k | like --block-size=1K |
| -l, --local | limit listing to local file systems |
| --no-sync | do not invoke sync before getting usage info (default) |
| -P, --portability | use the POSIX output format |
| --sync | invoke sync before getting usage info |
| -t, --type=TYPE | limit listing to file systems of type TYPE |
| -T, --print-type | print file system type |
| -x, --exclude-type=TYPE | limit listing to file systems not of type TYPE |
| --version | output version information and exit |
But among them, i used df -h. it displays the result in easy to read format. like
Filesystem Size Used Avail Use% Mounted on
/dev/hda3 39G 2.8G 34G 8% /
/dev/hda1 99M 11M 83M 12% /boot
none 254M 0 254M 0% /dev/shm
