Bash trigger wget command and don't wait for response, continue to the next command

Question

Is there a way I can trigger a wget command via bash script and continue to the next command in the bash script without waiting for a response from the wget? i am executing a command which should take lots of time and don't want wget to hold for a response nor re-trigger it after timeout has been timeout limit

Answer 1

You should use the --background option, as it goes to background and saves the output to a log

--background
       Go to background immediately after startup.  If no output file is specified via the -o, output is redirected to wget-log

Example:

$ wget http://cdimage.ubuntu.com/ubuntu-server/daily/current/wily-server-ppc64el.iso --background
Continuing in background, pid 79783.
Output will be written to ‘wget-log’.

$ cat wget-log
