| That's my beef, but, strictly speaking, neither do pushd/popd/dirs.
Those we have as (optional) functions only, but no-one uses
them (with the NetBSD sh) that I know of.
But they're not really in competition, a different solution to
a different problem.
| You might consider the ${param//old/new} expansion if it's available.
Not worth it, I prefer only portable sh code, it just isn't worth
the hassle of maintaining different versions for different shells.
| The directory stack is good for this as well,
Better for making temporary excursions while looking for
something, then returning. Too restricted for arbitrary
jumping between versions.
| I don't usually work with more
| than two directories at once, for which `cd -' suffices.
I currently have 6 complete NetBSD source trees (8, 9, 10-beta,
current, and testing (newer than current), plus the version that
generated the binaries installed in /bin (etc)) - retrofitting
updates into older versions (and to my running version) needs
the ability to flip around to all of those.
