If the command allows invocation without spaces, you can do this:
`command -e$a`
If the command allows invocation with a space *as part of the argument*
(many commands actually do allow this), then you can do this:
`command "-e $a"`
If neither of those is the case you can do something like this:
cmd = `command`
for x in a
cmd = `$cmd -e $x`
end
