Hi Chris,
Sorry, I forgot about 'cat' being a non-standard cmd. It's on this
machine as part of Cygwin. The one liner you gave me works great. It can
accept filenames as arguments and STDIN via a pipe. Howerver, what I am
going to be doing is too complex for a one line script so I will need to
put it in a .rb file. I thought the equivalent of the '-n -e "print"'
one liner would be:
while gets()
print
end
but, when I put this in a file called parser.rb and try
type input.txt | parser.rb
I get the following:
The process tried to write to a nonexistent pipe.
c:/scripts/parser.rb:1:in `gets': Bad file descriptor
(Errno::EBADF)
from c:/scripts/parser.rb:1
Thanks,
Stu

The following works on Win2k with ruby 1.8.2 (2004-12-25) [i386-mswin32]
type save_sql_env.txt | ruby -n -e "print"
I use 'type' as 'cat' is not a windows command in Win2k
