wget command to download a file and save as a different filename

Use the -O file option.

E.g.

wget google.com
...
16:07:52 (538.47 MB/s) - `index.html' saved [10728]

vs.

wget -O foo.html google.com
...
16:08:00 (1.57 MB/s) - `foo.html' saved [10728]

Also notice the order of parameters on the command line. At least on some systems (e.g. CentOS 6):

wget -O FILE URL

works. But:

wget URL -O FILE

does not work.

You would use the command Mechanical snail listed. Notice the uppercase O. Full command line to use could be:

wget www.examplesite.com/textfile.txt --output-document=newfile.txt

or

wget www.examplesite.com/textfile.txt -O newfile.txt

Hope that helps.

wget -O yourfilename.zip remote-storage.url/theirfilename.zip

will do the trick for you.

Note:

a) its a capital O.

b) wget -O filename url will only work. Putting -O last will not.

Either curl or wget can be used in this case. All 3 of these commands do the same thing, downloading the file at http://path/to/file.txt and saving it locally into "my_file.txt":

wget http://path/to/file.txt -O my_file.txt  # my favorite--it has a progress bar
curl http://path/to/file.txt -o my_file.txt
curl http://path/to/file.txt > my_file.txt

Notice the first one's -O is the capital letter "O".

The nice thing about the wget command is it shows a nice progress bar.

You can prove the files downloaded by each of the 3 techniques above are exactly identical by comparing their sha512 hashes. Running sha512sum my_file.txt after running each of the commands above, and comparing the results, reveals all 3 files to have the exact same sha hashes (sha sums), meaning the files are exactly identical, byte-for-byte.

Using CentOS Linux I found that the easiest syntax would be:

wget "link" -O file.ext

where "link" is the web address you want to save and "file.ext" is the filename and extension of your choice.
