Signals (GNU Wget 1.21.1-dirty Manual)
Since the purpose of Wget is background work, it catches the hangup signal (
SIGHUP) and ignores it. If the output was on standard output, it will be redirected to a file named
SIGHUP is ignored. This is convenient when you wish to redirect the output of Wget after having started it.
$ wget http://www.gnus.org/dist/gnus.tar.gz & ... $ kill -HUP %% SIGHUP received, redirecting output to `wget-log'.
Other than that, Wget will not try to interfere with signals in any way. C-c,
kill -TERM and
kill -KILL should kill it alike.
