rcalc and newlines

Hi,

How do I get rcalc to NOT output a newline at the end of its output. I'm using rcalc to compute a single number, and the newline is annoying.

If you can't get rcalc to do it, what is the command line voodoo required to strip it?

Thanks,

Chris

Christopher,
I would do this way by means of 'echo -n' :

···

---------------------------
#!/bin/csh -f
set a = `rcalc .....`
echo -n $a > output
----------------------------

Not sure it's what you are looking for..
BTW I hope it helps somehow...
cheers,
giulio

Use the rcalc -l and -o option together. For example:

  echo 17 | rcalc -l -o '${$1*2}'

will print out 34 without a newline.
