Summary:                    pkg-get can mess up shells on solaris express
Description: 
While I realize that OpenCSW probably doesn't explicitly support Solaris
Express, this problem will need to be fixed eventually.  When pkg-get is
run on Solaris Express, if any of the 'print "whatever" > /dev/fd/2'
statements are processed, the shell will have difficulties when it returns.
 Specifically, backspace will print "^H" instead of actually backspacing,
and usually if something visual is run after (vim for instance) the screen
with crop oddly.

The easiest way to test this is to run "pkg-get -i blah" (something that
it won't find), then type something and try to backspace it.

There is a simple fix, because the print statement support a -u option
that does exactly what "> /dev/fd/2" does without causing the problem. 
Thus, this line

gsed -i.bak -e 's/print\(.*\)>\/dev\/fd\/2/print -u 2\1/g'
/opt/csw/bin/pkg-get

will fix the problem and create a backup pkg-get.bak file in the process. 
The following line will do it without creating a backup.

gsed -ie 's/print\(.*\)>\/dev\/fd\/2/print -u 2\1/g' /opt/csw/bin/pkg-get

I don't disagree with you, it is Solaris Express' problem, but it's such an
easy "fix" on the pkg-get side (a simple gsed line), and it IS a problem
that lots of users will experience.  I realize it's not pkg-get's problem,
but given that print even supports a switch (-u) that makes redirection
unnecessary, why wouldn't you implement it and save lots of users the
headache?
