Re: [PLUG] /bin/sh alternative to bash's pushd and popd

Is there any way to implement (possibly with some coding)
functionality analogous to bash's directory stack but with /bin/sh?  I
am trying to write a shell script that may have to execute on sh.
Thanks in advance.

Yes, Cameron covers that on pages 103-106 in _Learning the bash Shell 3_ (and I understand he's working on the 4th edition).

Be sure to read the whole section because there are some caveats. Also, he is implementing these in bash, so it's possible these functions won't work in sh. I *think* they will work from a quick eyeball, but I don't really ever use sh, so... Here's the code:,+we+need+to+implement+pushd+and+popd+as+functions.++Here+are+our+initial+versions%22&source=bl&ots=2jBG6yLQnR&sig=9p7eaN1kXTX90UeD0RVzC_xQIqQ&hl=en&ei=zutmTNiZBoG78gaa0IC0BA&sa=X&oi=book_result&ct=result&resnum=3&ved=0CBcQ6AEwAg

They might at least provide a place to start.
