\subsection suspend-description Description
`suspend` suspends the current shell. In order to prevent suspending a
shell that isn't a subshell, it will not suspend a shell if it is a
login shell, or of `$SHLVLV` is less `$suspend_minimum_SHLVL`, which
defaults to three. This test is skipped if the `--force` option is
given or the shell is not interactive.
`suspend` suspends execution of the current shell by sending it a
SIGTSTP signal, returning to the controlling process. It can be
resumed later by sending it a SIGCONT. In order to prevent suspending
a shell that doesn't have a controlling process, it will not suspend a
the shell if it is a login shell or if `$SHLVLV` is less
`$suspend_minimum_SHLVL`, which defaults to three. This test is
skipped if the `--force` option is given or the shell is not
interactive.
