7@cindex unify duplicate translations
8@cindex duplicate removal
9The @code{msguniq} program unifies duplicate translations in a translation
10catalog.  It finds duplicate translations of the same message ID.  Such
11duplicates are invalid input for other programs like @code{msgfmt},
12@code{msgmerge} or @code{msgcat}.  By default, duplicates are merged
13together.  When using the @samp{--repeated} option, only duplicates are
14output, and all other messages are discarded.  Comments and extracted
15comments will be cumulated, except that if @samp{--use-first} is
16specified, they will be taken from the first translation.  File positions
17will be cumulated.  When using the @samp{--unique} option, duplicates are
18discarded.

20@subsection Input file location
21
22@table @samp
23@item @var{inputfile}
24Input PO file.
25
26@item -D @var{directory}
27@itemx --directory=@var{directory}
28@opindex -D@r{, @code{msguniq} option}
29@opindex --directory@r{, @code{msguniq} option}
30Add @var{directory} to the list of directories.  Source files are
31searched relative to this list of directories.  The resulting @file{.po}
32file will be written relative to the current directory, though.
33
34@end table
35
36If no @var{inputfile} is given or if it is @samp{-}, standard input is read.
37
38@subsection Output file location
39
40@table @samp
41@item -o @var{file}
42@itemx --output-file=@var{file}
43@opindex -o@r{, @code{msguniq} option}
44@opindex --output-file@r{, @code{msguniq} option}
45Write output to specified file.
46
47@end table
48
49The results are written to standard output if no output file is specified
50or if it is @samp{-}.

55@item -d
56@itemx --repeated
57@opindex -d@r{, @code{msguniq} option}
58@opindex --repeated@r{, @code{msguniq} option}
59Print only duplicates.
60
61@item -u
62@itemx --unique
63@opindex -u@r{, @code{msguniq} option}
64@opindex --unique@r{, @code{msguniq} option}
65Print only unique messages, discard duplicates.

73@itemx --properties-input
74@opindex -P@r{, @code{msguniq} option}
75@opindex --properties-input@r{, @code{msguniq} option}
76Assume the input file is a Java ResourceBundle in Java @code{.properties}
77syntax, not in PO file syntax.
78
79@item --stringtable-input
80@opindex --stringtable-input@r{, @code{msguniq} option}
81Assume the input file is a NeXTstep/GNUstep localized resource file in
82@code{.strings} syntax, not in PO file syntax.

86@subsection Output details
87
88@c --no-escape and --escape omitted on purpose.  They are not useful.
89

91@item -t
92@itemx --to-code=@var{name}
93@opindex -t@r{, @code{msguniq} option}
94@opindex --to-code@r{, @code{msguniq} option}
95Specify encoding for output.
96
97@item --use-first
98@opindex --use-first@r{, @code{msguniq} option}
99Use first available translation for each message.  Don't merge several
100translations into one.
101
102@item --force-po
103@opindex --force-po@r{, @code{msguniq} option}
104Always write an output file even if it contains no message.
105
106@item -i
107@itemx --indent
108@opindex -i@r{, @code{msguniq} option}
109@opindex --indent@r{, @code{msguniq} option}
110Write the .po file using indented style.
111
112@item --no-location
113@opindex --no-location@r{, @code{msguniq} option}
114Do not write @samp{#: @var{filename}:@var{line}} lines.
115
116@item -n
117@itemx --add-location
118@opindex -n@r{, @code{msguniq} option}
119@opindex --add-location@r{, @code{msguniq} option}
120Generate @samp{#: @var{filename}:@var{line}} lines (default).
121
122@item --strict
123@opindex --strict@r{, @code{msguniq} option}
124Write out a strict Uniforum conforming PO file.  Note that this
125Uniforum format should be avoided because it doesn't support the
126GNU extensions.
127
128@item -p
129@itemx --properties-output
130@opindex -p@r{, @code{msguniq} option}
131@opindex --properties-output@r{, @code{msguniq} option}
132Write out a Java ResourceBundle in Java @code{.properties} syntax.  Note
133that this file format doesn't support plural forms and silently drops
134obsolete messages.
135
136@item --stringtable-output
137@opindex --stringtable-output@r{, @code{msguniq} option}
138Write out a NeXTstep/GNUstep localized resource file in @code{.strings} syntax.
139Note that this file format doesn't support plural forms.
140
141@item -w @var{number}
142@itemx --width=@var{number}
143@opindex -w@r{, @code{msguniq} option}
144@opindex --width@r{, @code{msguniq} option}
145Set the output page width.  Long strings in the output files will be
146split across multiple lines in order to ensure that each line's width
147(= number of screen columns) is less or equal to the given @var{number}.
148
149@item --no-wrap
150@opindex --no-wrap@r{, @code{msguniq} option}
151Do not break long message lines.  Message lines whose width exceeds the
152output page width will not be split into several lines.  Only file reference
153lines which are wider than the output page width will be split.
154
155@item -s
156@itemx --sort-output
157@opindex -s@r{, @code{msguniq} option}
158@opindex --sort-output@r{, @code{msguniq} option}
159Generate sorted output.  Note that using this option makes it much harder
160for the translator to understand each message's context.
161
162@item -F
163@itemx --sort-by-file
164@opindex -F@r{, @code{msguniq} option}
165@opindex --sort-by-file@r{, @code{msguniq} option}
