Display the list of currently remembered directories. Directories
find their way onto the list with the `pushd' command; you can get
back up through the list with the `popd' command.
The -l flag specifies that `dirs' should not print shorthand versions
of directories which are relative to your home directory. This means
that `~/bin' might be displayed as `/homes/bfox/bin'. The -v flag
causes `dirs' to print the directory stack with one entry per line,
prepending the directory name with its position in the stack. The -p
flag does the same thing, but the stack position is not prepended.
The -c flag clears the directory stack by deleting all of the elements.
