Isso não tem nada a ver com bash
, mas depende das conclusões programadas no pacote bash-completion
.
De alguns comentários no arquivo /etc/bash_completion.d/mount
:
# mount(8) completion. This will pull a list of possible mounts out of
# /etc/{,v}fstab, unless the word being completed contains a ':', which
# would indicate the specification of an NFS server. In that case, we
# query the server for a list of all available exports and complete on
# that instead.
#
# umount(8) completion. This relies on the mount point being the third
# space-delimited field in the output of mount(8)
#
Além disso, você encontra no arquivo principal /etc/bash_completion
o seguinte comentário, que fala explicitamente sobre os comandos mount
e umount
:
# A meta-command completion function for commands like sudo(8), which need to
# first complete on a command, then complete according to that command's own
# completion definition - currently not quite foolproof (e.g. mount and umount
# don't work properly), but still quite useful.
#
Atualizar :
O comentário sobre os comandos mount
e umount
foi removido de bash_completion
no confirmar :
_command_offset: Restore compopts used by called command.
This fixes completions that rely on their compopts, most notably
mount(8).
Fixes bash-completion bug #313183.
