Here are some awesome examples:

1. Download Single File with wget

The following example downloads a single file from internet and stores in the current directory.

 $ wget http://www.openss7.org/repos/tarballs/strx25-0.9.2.1.tar.bz2

While downloading it will show a progress bar with the following information:

• %age of download completion (for e.g. 31% as shown below)
• Total amount of bytes downloaded so far (for e.g. 1,213,592 bytes as shown below)
• Current download speed (for e.g. 68.2K/s as shown below)
• Remaining time to download (for e.g. eta 34 seconds as shown below)

Download in progress:

 $ wget http://www.openss7.org/repos/tarballs/strx25-0.9.2.1.tar.bz2Saving to: `strx25-0.9.2.1.tar.bz2.1'

31% [=================> 1,213,592   68.2K/s  eta 34s

2. Download and Store With a Different File name Using wget -O

By default wget will pick the filename from the last word after last forward slash, which may not be appropriate always.
 

Wrong: Following example will download and store the file with name: download_script.php?src_id=7701
 

$ wget http://www.vim.org/scripts/download_script.php?src_id=7701 Even though the downloaded file is in zip format, it will get stored in the file as shown below.
 

$ ls download_script.php?src_id=7701 Correct: To correct this issue, we can specify the

output file name using the -O option as:
 

$ wget -O taglist.zip http://www.vim.org/scripts/download_script.php?src_id=7701

3.Continue the Incomplete Download Using wget -c
Restart a download which got stopped in the middle using wget -c option as shown below.

 $ wget -c http://www.openss7.org/repos/tarballs/strx25-0.9.2.1.tar.bz2

This is very helpful when you have initiated a very big file download which got interrupted in the middle. Instead of starting the whole download again, you can start the download from where it got interrupted using option -c
 

Note: If a download is stopped in middle, when you restart the download again without the option -c, wget will append .1 to the filename automatically as a file with the previous name already exist. If a file with .1 already exist, it will download the file with .2 at the end.
