On my research list: [WayBack] bash – aliasing cd to pushd – is it a good idea? – Unix & Linux Stack Exchange
It has a nice discussion on complements to pushd/popd/cd/dirs including a very nice set of navd scripts that eases the navigation of the directory stack.
I found it because the ESXi busybox does not have pushd and popd and a cd won’t work from inside a shell script: [WayBack] linux – Why doesn’t “cd” work in a bash shell script? – Stack Overflow
It also made me find out that the ESXi busybox does support cd - to go to the previous directory. More info on that cd syntax is at [WayBack] bash – Difference between “cd -” and “cd ~-” – Unix & Linux Stack Exchange
