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

Displays:

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
