My pkgsrccon slide may have given the wrong impression - I assume the
grep stage is in there to catch the occurrence when awk tries to print
a second argument which doesn't exist.  What I was trying to convey
was that it might be better to do that in awk itself:  i.e.

[13:24:10] agc@sys3 ...pkgsrc/graphics/tiff 49 > pkg_info -qp libtool-base | awk '{ if (NF > 1) { print $2; exit }}'
/usr/pkg
[13:24:35] agc@sys3 ...pkgsrc/graphics/tiff 50 > echo "@cwd" | awk '{ if (NF > 1) { print $2; exit }}'
[13:24:56] agc@sys3 ...pkgsrc/graphics/tiff 51 >

If I've picked up the problem set wrongly, please say.

Thanks,
