If you have a lot of places that you routinely visit in your file system, often with ludicrously long path names, then click here to download a tar file that will alleviate the problem (once downloaded, execute `tar -xvf pyfsmem.tar` to obtain the python 3.x script).
Follow instructions in the script’s prolog (especially adding aliases to your bashrc). Then you can “remember” frequently visited directories and return to them with only a couple of keystrokes.
IMO, this is far better than pushd and popd because favorite places are remembered indefinitely (even with power failures).
Thanks to M. Scot Swan for providing this gem!
