Re: \r in variables and test


Samuel Thibault wrote:
Hi,

In a ./configure script, I call a test program (native python, actually)
that outputs "True\r\n" and I put this result in variable foo. The
problem is that [ "$foo" = True ] doesn't return true because foo
actually contains True\r, not True.

Is there a nice way around this?

You haven't provided sufficient information about which bits you are willing to change.


Some things you could do are:

* use Cygwin Python
* change the Python script to output \n instead of \r\n
* [ $foo = $'True\r' ]
* [ ${foo/%$'\r'/} = True ]

The last has the advantage that it will work even if the script outputs only "True\n" instead of \r\n.
