If are a Bash user and you are in a directory and need to go else where for a while but don't want to lose where you were, use pushd instead of cd.
cd /home/complicated/path/.I/dont/want/to/forget
pushd /tmp
cd thing/in/tmp
popd (returns you to /home/complicated/path/.I/dont/want/to/forget)
There are 9 alternatives - vote for the best!

I recommend to alias pushd and popd to + and -, respectively. They are easier to remember and faster to type.
alias +='pushd'alias -- -='popd'Try 'cd -' ..same
cd - is not the same as it only remembers the last directory you were in. It's great for flipping between two directories, but if you want to "save" a directory long term then push/pop is the better way
If you get really used to pushd/popd, you'll find yourself opening less terminals/screen windows.
Also, typing 'dirs -v' will show you your current directory stack. If you type pushd without any args, it'll reverse the top 2 dirs in the stack. You can also rotate with pushd +n, -n, etc. See your shell's man page.
I really liked the aliases created by hfs user, and added a "?" one for dirs -v :)
alias +='pushd'alias -- -='popd'alias ?='dirs -v'
