wget: Signals
8.8 Signals
===========
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 ‘wget-log’. Otherwise, ‘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.
