This is very unconvential usage.  Your program should always
accept hosts as specified, ie:

  shc host1 host2 host3

You may chose to add functionality to read from a file, but that should
not change the normal use case.  That is, you could do

  shc -f file1 host1 host2 host3

in which case the tool would parse file1 and also operate on host1,
host2 and host3.

If you wish to allow multiple files to be given, it would have to be

  shc -f file1 -f file2 host1 host2 host3

This is still somewhat uncommon, and I'd probably suggest to stipulate
that if the '-f' option is given, the tool expects there to be exactly
one file and any additional arguments would be errors (ie, if '-f' is
given, don't read hostnames).

  shc -f file1
