Xanda - /dev/project - Run wget in background for an unattended download of files

Here is quick tip, if you wish to perform an unattended download of large files such as Linux DVD ISO use wget as follows:

wget -bqc


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

=> -q : Turn off Wget’s output aka save disk space.

=> -c : Resume broken download i.e. continue getting a partially-downloaded file. This is useful when you want to finish up a download started by a previous instance of Wget, or by another program.

This tip will save your time while downloading large ISO image from the internet.

You can also use nohup command to execute commands after you exit from a shell prompt:

$ nohup wget &

$ exit
