The man page for screen says that I can create a detatched screen running with a set command in it by doing this:
$ screen -dm $command
However, it doesn't work. Screen exits without creating the detached screen.
screen -dm isn't the same as screen -d -m. Try the latter.
Just an FYI...
You *may* be right, however...
"Standards" dictate that "flags" can be combined into a single parameter. This is "eased" (debatable IMO) by the "getopts" function in bash, getopt(1) command and getopt(3) function call for C et al.
You are right to the extent that posix getopt does indeed allow "-dn" as equivalent to "-d -n". But, _lots_ of programs use their own option parsing so assuming the above would be very foolish.
Unfortunately, *some* few programs do not implement this correctly.
That I belive is a major understatement...
