Linux – koÄľko je ešte voÄľnĂ©ho miesta na HDD
Na zistenie veÄľkosti voÄľnĂ©ho miesta na disku slúži prĂkaz df. Tento prĂkaz zobrazĂ aktuálne vyuĹľitie miesta na pevnom disku/diskoch a pripojenĂ˝ch zariadeniach.
Výstup je približne takýto:
Filesystem 1K-blocks Used Available Use% Mounted on
rootfs 15328248 7238380 7311488 50% /
/dev/root 15328248 7238380 7311488 50% /
tmpfs 18808 212 18596 2% /run
tmpfs 5120 0 5120 0% /run/lock
tmpfs 37616 4 37612 1% /tmp
tmpfs 10240 0 10240 0% /dev
tmpfs 37616 0 37616 0% /run/shm
ZobrazenĂ© informácie sĂş zrozumiteÄľnĂ©, ale pre jednoduchšie porozumenie je vhodnĂ© pouĹľiĹĄ parameter -h alebo tieĹľ –human-readable
df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 15G 7.0G 7.0G 50% /
/dev/root 15G 7.0G 7.0G 50% /
tmpfs 19M 212K 19M 2% /run
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 37M 4.0K 37M 1% /tmp
tmpfs 10M 0 10M 0% /dev
tmpfs 37M 0 37M 0% /run/shm
Tu je kompletný zoznam parametrov, ktoré môžete s df použiť:
Usage: df [OPTION]... [FILE]...
Show information about the file system on which each FILE resides,
or all file systems by default.
Mandatory arguments to long options are mandatory for short options too.
-a, --all include dummy file systems
-B, --block-size=SIZE scale sizes by SIZE before printing them. E.g.,
`-BM' prints sizes in units of 1,048,576 bytes.
See SIZE format below.
--total produce a grand total
-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
-v (ignored)
--help display this help and exit
--version output version information and exit
Display values are in units of the first available SIZE from --block-size,
and the DF_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables.
Otherwise, units default to 1024 bytes (or 512 if POSIXLY_CORRECT is set).
SIZE may be (or may be an integer optionally followed by) one of following:
KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.
