From: "michelemdl@..." Date: 2001-12-01T06:43:07+09:00 Subject: [ruby-talk:27133] external commands I need to exec an external programm from a ruby script. The name of the external command is ALADDIN. This is what I do under Linux: ... 'ALADDIN -f inputfile.std > outputfile.std' #line in ruby script to call the external program ALADDIN # ... Doing the same under windows doesn' t work. How can I do that under windows? Thanks, Michele
