Come calcolare su Unix lo spazio disco ??

tramite il comando du (abbreviazione di disk usage, utilizzo del disco) è un comando dei sistemi operativi Unix e Unix-like,il quale calcola e visualizza il totale dello spazio nel file system occupato dai file o directory specificate.

Tag Description
-a, –all write counts for all files, not just directories
–apparent-size
print apparent sizes, rather than disk usage; although the apparent size is usually smaller, it may be larger due to holes in (‘sparse’) files, internal fragmentation, indirect blocks, and the like
-B, –block-size=SIZE use SIZE-byte blocks
-b, –bytes
equivalent to ‘–apparent-size –block-size=1
-c, –total
produce a grand total
-D, –dereference-args
dereference FILEs that are symbolic links
–files0-from=F
summarize disk usage of the NUL-terminated file names specified in file F
-H like –si, but also evokes a warning; will soon change to be equivalent to –dereference-args (-D)
-h, –human-readable
print sizes in human readable format (e.g., 1K 234M 2G)
–si like -h, but use powers of 1000 not 1024
-k like –block-size=1K
-l, –count-links
count sizes many times if hard linked
-m like –block-size=1M
-L, –dereference
dereference all symbolic links
-P, –no-dereference
don’t follow any symbolic links (this is the default)
-0, –null end each output line with 0 byte rather than newline
-S, –separate-dirs
do not include size of subdirectories
-s, –summarize
display only a total for each argument
-x, –one-file-system
skip directories on different file systems
-X FILE, –exclude-from=FILE
Exclude files that match any pattern in FILE.
–exclude=PATTERN Exclude files that match PATTERN.
–max-depth=N
print the total for a directory (or file, with –all) only if it is N or fewer levels below the command line argument; –max-depth=0 is the same as –summarize
–time show time of the last modification of any file in the directory, or any of its subdirectories
–time=WORD
show time as WORD instead of modification time: atime, access, use, ctime or status
–time-style=STYLE show times using style STYLE:
full-iso, long-iso, iso, +FORMAT FORMAT is interpreted like ‘date’
–help display this help and exit
–version
output version information and exit

 

Esempio:

du -sh *
questo comando elenca tutte le cartelle ed il loro relativo spazio occupato.
