NAME¶
nydiff - tool to compare two versions of a specialized-format patch
SYNOPSIS¶
nydiff oldpam newpam name options [
print ] [ .go ]
DESCRIPTION¶
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.
USAGE¶
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.
OPTIONS¶
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.
- F
- "force" - Bypass the second sanity check on
sufficient matching.
- H
- Print help information only.
