Often, download the packages or files from the different websites using the WGET command in the Linux distro. I would like to specify the location to save the file to the destination with a file name and extension.
 

-O,  --output-document=FILE  write documents to FILE

wget <URI> -O /path/to/file.ext

$ sudo wget http://updates.jenkins-ci.org/latest/jenkins.war -O  /usr/share/jenkins/jenkins.war

 
-P prefix
--directory-prefix=prefix
           Set directory prefix to prefix.  The directory prefix is the
           directory where all other files and sub-directories will be
           saved to, i.e. the top of the retrieval tree.  The default
           is . (the current directory).
           
wget <URI> -P /path/to/folder
