eval just evaluates arguments and hence does the same argument splitting as shell does when it receives a command, you can see it if you do 'set -x' before running the command. In this case eval gets two arguments: 'vim' and '"/some/dir/a" "/some/dir/b" ', after splitting the command run is vim "/some/dir/a" "/some/dir/b" (quoted) which is why spaces, etc. are preserved. As for OP's original scenario, I left it out as you already answered it. Note that there's also a shortcut for cat (without launching a subprocess): $ vim $(< listfile) -- Michael Gliwinski Henderson Group Information Services 9-11 Hightown Avenue, Newtownabby, BT36 4RT Phone: 028 9034 3319 ********************************************************************************************** The information in this email is confidential and may be legally privileged.
