\bl sends the TERM (terminate, 15) signal to the specified
processes. If a signal name or number preceded by `-' is
given as first argument, that signal is sent instead of ter-
minate (see _

\bi_
\bg_

\bc(2)). The signal names are listed by
`kill -l', and are as given in /_

stripped of the common SIG prefix.
The terminate signal will kill processes that do not catch
the signal; `kill -9 ...' is a sure kill, as the KILL (9)
signal cannot be caught. By convention, if process number 0
is specified, all members in the process group (i.e.
processes resulting from the current login) are signaled
(but beware: this works only if you use _
\bs_
\bh(1); not if you
use _
\bc_
\bs_
\bh(1).) Negative process numbers also have special
meanings; see _
\bk_
\bi_
\bl_
\bl(2) for details.
The killed processes must belong to the current user unless
The process number of an asynchronous process started with
`&' is reported by the shell. Process numbers can also be
found by using _
\bp_
\bs(1). _

\bl is a built-in to _
\bc_
\bs_
\bh(1); it
allows job specifiers of the form ``%...'' as arguments so
process id's are not as often used as _
\bk_
\bi_
\bl_
\bl arguments. See
_
\bc_
\bs_
\bh(1) for details.
