Use eval (and be careful with your quoting! Bonus points for explaining why
the output redirect below has to be in the quotes, but the input redirect
can't):
_null=">/dev/null 2>&1"
eval "cat $_null" <<EOF
~ This goes to the bit-bucket!
EOF
But why not just use the mechanism *ALREADY* in place for discarding output,
the 'qt' (or Quiet) function:
<from /bin/POSIXness>
qt () { "$@" >/dev/null 2>&1 ; }
...and it's friend, qte (swallows error out, but leaves main out alone):
qte () { "$@" 2>/dev/null ; }
Use it like so:
if qt mount.back $pkgname $pkgmnt ; then
