NAME
pdfdiff — compare two Product Description Files
SYNOPSIS
pdfdiff
[-n]
[-p
percent]
pdf1 pdf2
DESCRIPTION
pdfdiff
is a program that compares two
PDFs
(Product Description Files).
The
PDFs
can be generated using the
mkpdf
command (see
mkpdf(1M)).
Individual fields in the
PDFs
are compared, and differences found in these fields are reported.
For a detailed explanation of the
PDF
fields see
pdf(4).
The report format is:
pathname: diff_field[(details) ][ ,...]
diff_field
is one of the field names specified in
pdf(4).
The format of
details
is
``oldvalue -> newvalue''
and may include an additional
``(added description)''.
A summary of total product growth in bytes,
DEV_BSIZE
disk blocks, and the percentage change in disk blocks is reported.
This summary includes growth of all files,
including those for which growth did
not
exceed the threshhold
percent.
Format of the growth summary is:
Growth: x bytes, y blocks (z%)
Options
pdfdiff
recognizes the following options:
- -n
Compare numerical representation of user
ID
uid
and group
ID
gid
of each file, instead of the usual text representation.
If owner or group is recorded in the
PDF
as a name, look the name up in the
/etc/passwd
or
/etc/group
file, respectively, to find the
ID
number.
- -p percent
specifies a threshhold percentage for file growth.
Files having a net size change greater than or equal to
this percentage are reported.
A decrease in size is reported as a negative number.
If
-p
is not specified, a default value of zero percent is used.
EXAMPLES
The following output results when the
/usr/bin/cat
entry in the example from
pdf(4)
is different in the compared
PDF:
/usr/bin/cat: mode(-r-xr-xr-x -> -r-sr-xr-x)(became suid), size(27724 -> 10345),
checksum(1665 -> 398)
Growth: -17379 bytes, -17 blocks (-4%)
WARNING
Use of PDFs is discouraged since this functionality is obsolete and is being
replaced with Software Distributor (see
sd(4)).
