24.2.3 Pipelines
----------------

A 'gdbmtool' command can be followed by a pipe sign ('|') and a shell
command.  This construct (a "pipeline") works the same way as in Bourne
shell: the output of 'gdbmtool' command to the left of '|' is connected
to the input of the shell command to the right of it.  This latter
command will be run using '$SHELL -c'.

   For example, to print the directory of the GDBM file sorted by bucket
address, one would do:

     dir | sed 1,4d | sort -k3n

(the table begins at line 5, so first four lines are removed, and the
bucket address is listed in column 3).
