-N
Synopsis
The database files used for aliases always store keys with a null byte appended to each. When you use editmap on such a file, your key will not be found:
% editmap -q hash list-aliases user
editmap: couldn't find key user in map list-aliases
This lookup failed because editmap normally
omits a trailing null from a key before looking up its value. When
looking up keys in aliases-style databases, you
need to use the -N
command-line switch to append a
null to a key before a lookup:
% editmap -q -N hash list-aliases user
Some database files (other than aliases) also
append a null byte to keys. These databases will appear with a
corresponding -N
in a K
configuration file line. In such instances, you must use
-N
with editmap to match the
K
line’s -N
