Whether or not single quotes work depends on the command, as it's the command that has
to parse the argument list.
Those commands that don't take wildcards you can run inside of a for loop...for
example:
for %f in (*.htm) do perl -e '-s/f:/g:/gi' -p -i.bak %f
cmd.exe (as opposed to command.com) has a number of options for the for command...for
/? will show them.

1) As far as I know, you need to use "double quotes" rather than 'single
quotes' in Win95/98/NT/2000 -- single quotes work fine under Unix shells but
not under cmd.exe/command.com.
2) Unix shells expand wildcards such as *.htm; DOS does not. One way to get
expansion is to use Jenda's G module, available e.g. from
http://jenda.mccann.cz/#G or with PPM (location
http://Jenda.McCann.cz/perl). Add "-MG" without the quotes to the
environment variable PERL5OPT and you can use *.htm.
3) (minor nitpick) it's usually called a "one-liner", rather than "single
liner".
Cheers,
Philip
