unshareall
shareall(1M) System Administration Commands shareall(1M)NAME
shareall, unshareall - share, unshare multiple resources
SYNOPSIS
shareall [ -F FSType [ ,FSType...]] [-| file]
unshareall [ -F FSType [ ,FSType...]]
DESCRIPTION
When used with no arguments, shareall shares all resources from file, which contains a list of share command lines. If the operand is a
hyphen (-), then the share command lines are obtained from the standard input. Otherwise, if neither a file nor a hyphen is specified,
then the file /etc/dfs/dfstab is used as the default.
Resources may be shared by specific file system types by specifying the file systems in a comma-separated list as an argument to -F.
unshareall unshares all currently shared resources. Without a -F flag, it unshares resources for all distributed file system types.
OPTIONS -F FSType Specify file system type. Defaults to the first entry in /etc/dfs/fstypes.
FILES
/etc/dfs/dfstab
