filesystem.
Turns on filesystem quotas. Options specify quota for users (-u),
groups (-g), and force (-f).
Turns off filesystem quotas. Options specify quota for users (-u),
groups (-g), and force (-f).
Clears quota files (administrative quota files if used without -f,
operational quota files otherwise), all of their quota entries for users
(-u) or groups (-g). After running quotainv, you must run quotacheck
before using quotas.
CAUTION: Use extreme caution when using this command; its
results cannot be undone.
Switches to new quota mode (-n) or old quota mode (-o).
Sets filesystem quotas for users or groups. Limits can be specified
with --{block|inode}-{softlimit|hardlimit} or their short equivalents -
b, -B, -i, -I. Users can set 1, 2, 3 or 4 limits. ‡ Also, limits can be
specified with special suffixes, -b, -k, -m, -g, -t, and -p to indicate
units of 1, 2^10, 2^20, 2^30, 2^40 and 2^50, respectively. By default,
the block limits unit is 1 kilobyte (1,024), and block limits are always
kilobyte-grained (even if specified in bytes). See Examples.
Sets filesystem quota grace times for users or groups. Grace time is
specified in “XXwXXdXXhXXmXXs” format or as an integer seconds
value. See Examples.
