nydiff oldpam newpam name options [ print ] [ .go ]

nydiff is a tool in the Nypatchy suite of programs for working with Patchy Master Files (PAM files); see nypatchy(1). Specifically, it compares two different versions of the same PAM file and generates a "correction patch" that can be used by nypatchy to update the older version to the newer version.

The parameter oldpam is the name of the older version of the PAM file (a default extension of ".car" is assumed), newpam is the name of the newer version, print is the output file to write to (the default is standard output if omitted), and options is a sequence of single-character flags. The parameter name is the name to be used for the correction file to be generated (the specific filename will be name.ucra for a correction patch to be used by Nypatchy).

The command should be ended with ".go" unless one wants to enter the Nypatchy interactive shell.

Note that options should be given as a single string of characters with no space separation and no use of the - character (except that it can be used in place of the options field if no options are desired). Alphabetic options are not case-sensitive.

A

"anyway" - Bypass the first sanity check on sufficient matching.
