Using makedbm to Modify a Non-Default Map
There are two different methods for using makedbm to modify maps if you do not
have an input file:
-
Redirect the makedbm -u output to a temporary file,
modify the file, then use the modified file as input to makedbm.
-
Have the output of makedbm -u operated on
within a pipeline that feeds into makedbm. This is appropriate if you can update the
disassembled map with either awk, sed, or a cat
append.
