16 debdiff takes the names of two Debian package files (.debs or .udebs)
17 on the command line and compares their contents (considering only the
18 files in the main package, not the maintenance scripts). It shows
19 which files have been introduced and which removed between the two
20 package files, and is therefore useful for spotting files which may
21 have been inadvertently lost between revisions of the package. It also
22 checks the file owners and permissions, and compares the control files
23 of the two packages using the wdiff program. If you want a deeper com‐
24 parison of two Debian package files you can use the diffoscope tool.
25 If no arguments are given, debdiff tries to compare the content of the
27 current source directory with the last version of the package.
28 debdiff can also handle changes between groups of .deb files in two
30 ways. The first is to specify two .changes files. In this case, the
31 .deb files listed in the .changes file will be compared, by taking the
32 contents of all of the listed .deb files together. (The .deb files
33 listed are assumed to be in the same directory as the .changes file.)
34 The second way is to list the .deb files of interest specifically using
35 the --from ... --to syntax. These both help if a package is broken up
36 into smaller packages and one wishes to ensure that nothing is lost in
37 the interim.
38 debdiff examines the devscripts configuration files as described below.
40 Command line options override the configuration file settings, though.
41 If debdiff is passed two source packages (.dsc files) it will compare
43 the contents of the source packages. If the source packages differ
44 only in Debian revision number (that is, the .orig.tar.gz files are the
45 same in the two .dsc files), then interdiff(1) will be used to compare
46 the two patch files if this program is available on the system, other‐
47 wise a diff will be performed between the two source trees.
48
50 --dirs, -d
51 The default mode of operation is to ignore directory names which
52 appear in the file list, but they, too, will be considered if
53 this option is given.
54 --nodirs
56 Ignore directory names which appear in the file list. This is
57 the default and it can be used to override a configuration file
58 setting.
59 --move FROM TO, -m FROM TO
61 It sometimes occurs that various files or directories are moved
62 around between revisions. This can be handled using this
63 option. There are two arguments, the first giving the location
64 of the directory or file in the first package, and the second in
65 the second. Any files in the first listing whose names begin
66 with the first argument are treated as having that substituted
67 for the second argument when the file lists are compared. Any
68 number of --move arguments may be given; they are processed in
69 the order in which they appear. This only affects comparing
70 binary packages, not source packages.
71 --move-regex FROM TO
73 This is the same as --move, except that FROM is treated as a
74 regular expression and the perl substitution command s/^FROM/TO/
75 is applied to the files. In particular, TO can make use of
76 backreferences such as $1.
77 --nocontrol
79 debdiff will usually compare the respective control files of the
80 packages using wdiff(1). This option suppresses this part of
81 the processing.
82 --control
84 Compare the respective control files; this is the default, and
85 it can be used to override a configuration file setting.
86 --controlfiles FILE[,FILE ...]
88 Specify which control files to compare; by default this is just
89 control, but could include postinst, config and so on. Files
90 will only be compared if they are present in both .debs being
91 compared. The special value ALL compares all control files
92 present in both packages, except for md5sums. This option can
93 be used to override a configuration file setting.
94 --wdiff-source-control
96 When processing source packages, compare control files using
97 wdiff. Equivalent to the --control option for binary packages.
98 --no-wdiff-source-control
100 Do not compare control files in source packages using wdiff.
101 This is the default.
102 --wp, --wl, --wt
104 Pass a -p, -l or -t option to wdiff respectively. (This yields
105 the whole wdiff output rather than just the lines with any
106 changes.)
107 --show-moved
109 If multiple .deb files are specified on the command line, either
110 using .changes files or the --from/--to syntax, then this option
111 will also show which files (if any) have moved between packages.
112 (The package names are simply determined from the names of the
113 .deb files.)
114 --noshow-moved
116 The default behaviour; can be used to override a configuration
117 file setting.
118 --renamed FROM TO
120 If --show-moved is being used and a package has been renamed in
121 the process, this command instructs debdiff to treat the package
122 in the first list called FROM as if it were called TO. Multiple
123 uses of this option are permitted.
124 --exclude PATTERN
126 Exclude files that match PATTERN. Multiple uses of this option
127 are permitted.
128 --diffstat
130 Include the result of diffstat before the generated diff.
131 --no-diffstat
133 The default behaviour; can be used to override a configuration
134 file setting.
135 --auto-ver-sort
137 When comparing source packages, do so in version order.
138 --no-auto-ver-sort
140 Compare source packages in the order they were passed on the
141 command-line, even if that means comparing a package with a
142 higher version against one with a lower version. This is the
143 default behaviour.
144 --unpack-tarballs
146 When comparing source packages, also unpack tarballs found in
147 the top level source directory to compare their contents along
148 with the other files. This is the default behaviour.
149 --no-unpack-tarballs
151 Do not unpack tarballs inside source packages.
152 --no-conf, --noconf
154 Do not read any configuration files. This can only be used as
155 the first option given on the command-line.
156 --debs-dir directory
158 Look for the .dsc files in directory instead of the parent of
159 the source directory. This should either be an absolute path or
160 relative to the top of the source directory.
161 --help, -h
163 Show a summary of options.
164 --version, -v
166 Show version and copyright information.
167 --quiet, -q
169 Be quiet if no differences were found.
170 --ignore-space, -w
172 Ignore whitespace in diffs.
173
175 The two configuration files /etc/devscripts.conf and ~/.devscripts are
176 sourced by a shell in that order to set configuration variables. Com‐
177 mand line options can be used to override configuration file settings.
178 Environment variable settings are ignored for this purpose. The cur‐
179 rently recognised variables are:
180 DEBDIFF_DIRS
182 If this is set to yes, then it is the same as the --dirs command
183 line parameter being used.
184 DEBDIFF_CONTROL
186 If this is set to no, then it is the same as the --nocontrol
187 command line parameter being used. The default is yes.
188 DEBDIFF_CONTROLFILES
190 Which control files to compare, corresponding to the --con‐
191 trolfiles command line option. The default is control.
192 DEBDIFF_SHOW_MOVED
194 If this is set to yes, then it is the same as the --show-moved
195 command line parameter being used.
196 DEBDIFF_WDIFF_OPT
198 This option will be passed to wdiff; it should be one of -p, -l
199 or -t.
200 DEBDIFF_SHOW_DIFFSTAT
202 If this is set to yes, then it is the same as the --diffstat
203 command line parameter being used.
204 DEBDIFF_WDIFF_SOURCE_CONTROL
206 If this is set to yes, then it is the same as the
207 --wdiff-source-control command line parameter being used.
208 DEBDIFF_AUTO_VER_SORT
210 If this is set to yes, then it is the same as the
211 --auto-ver-sort command line parameter being used.
212 DEBDIFF_UNPACK_TARBALLS
214 If this is set to no, then it is the same as the
215 --no-unpack-tarballs command line parameter being used.
216 DEBRELEASE_DEBS_DIR
218 This specifies the directory in which to look for the .dsc and
219 files, and is either an absolute path or relative to the top of
220 the source tree. This corresponds to the --debs-dir command
221 line option. This directive could be used, for example, if you
222 always use pbuilder or svn-buildpackage to build your packages.
223 Note that it also affects debrelease(1) in the same way, hence
224 the strange name of the option.
225
227 Normally the exit value will be 0 if no differences are reported and 1
228 if any are reported. If there is some fatal error, the exit code will
229 be 255.
