command < inputfile

just specifys an input file for command. This makes the shell open the file and run the command with the file already opened. Some commands can open their own input files. But as you saw here, some of them perform screwball tests and refuse to open perfectly good files. So I prefer this syntax.

command > outputfile is the same deal but in the other direction. This is more often the only game in town because lots of commands can't open an output file...the shell must do it for them.

command < inputfile > outputfile &
will place the command in the background, but it exit if you close the session.

nohup command < inputfile > outputfile &
will background the command and protect it from hangup signals. So it will continue if you close the session.
