NAME

umount - unmount filesystems

SYNOPSIS

ast_umount [ options ] [ fs | dir ]

DESCRIPTION

umount unmounts one or more currently mounted filesystems, which can be specified either as mounted-on directories or filesystems.

OPTIONS

-a, --all
Operate on all filesystems in the filesystem table. The --host and --type options can be used to match parts of the table.
-f, --show|fake
Display but do not execute the underlying umount(2) system calls.
-h, --hosts=[!]host,...
Limit the filesystem table scan to entries matching the host names. A leading ! inverts the match sense.
-M, --mtab|fstab=file
Use file instead of the default filesystem table.
-b, --omit=[!]type,...
Omit filesystem table entries matching any of the type names.
-t|T, --types=[!]type,...
Limit the filesystem table scan to entries matching the type names. A leading ! inverts the match sense.
-m, --multiplex|nproc
Distribute multiple mounts across nproc processes. Ignored by this implementation.
-P, --prefix=string
Ignored by this implementation.
-v, --verbose
Ignored by this implementation.
