I tried the following :[$] wget http://cdn.edgecast.steamstatic.com/steam/apps/256679148/movie480.webm > Conan1.webm                                                     [1:21:05]--2017-02-23 01:51:50--  http://cdn.edgecast.steamstatic.com/steam/apps/256679148/movie480.webmResolving cdn.edgecast.steamstatic.com (cdn.edgecast.steamstatic.com)... 117.18.232.131Connecting to cdn.edgecast.steamstatic.com (cdn.edgecast.steamstatic.com)|117.18.232.131|:80... connected.HTTP request sent, awaiting response... 200 OKLength: 11255413 (11M) [video/webm]Saving to: movie480.webmmovie480.webm                       100%[===================================================================>]  10.73M  33.7KB/s    in 6m 25s  2017-02-23 01:58:16 (28.6 KB/s) - movie480.webm saved [11255413/11255413]As can be seen the first part of the command worked, wget downloaded the file but the second part of the command that renaming the file, in this case a very generic movie480.webm was downloaded. Why wasn't conan1.webm , the name I had suggested it took. I do know that if I had done -$ mv  movie480.webm conan1.webm then it would work, but this means an additional command. Why that failed ? Could there have been another way to do the same thing in a single command though similar to shown above?
Why doesn't wget url/mediafile.ext > medafile2.ext work?
command line;zsh;io redirection;wget
You didn't suggest it took the name Conan1.webm, you redirected its standard output stream to file called Conan1.webm. Since wget doesn't write to standard output by default, that has no effect on where the content is saved.See man wget - in particular the -O option:-O file--output-document=file    The documents will not be written to the appropriate files, but all    will be concatenated together and written to file.  If - is used as    file, documents will be printed to standard output, disabling link    conversion.  (Use ./- to print to a file literally named -.)So you could have usedwget -O Conan1.webm http://cdn.edgecast.steamstatic.com/steam/apps/256679148/movie480.webm orwget -O- http://cdn.edgecast.steamstatic.com/steam/apps/256679148/movie480.webm > Conan1.webm
