Subject: man pages for diff et al. I finally got tired of not having man pages for diff and friends, so I edited the appropriate sections of the texinfo manual into man format.

.TH DIFF 1 "22sep1993" "GNU Tools" "GNU Tools"
|
||||
.SH NAME
|
||||
diff \- find differences between two files
|
||||
.SH SYNOPSIS
|
||||
.B diff
|
||||
[options] from-file to-file
|
||||
.SH DESCRIPTION
|
||||
In the simplest case,
|
||||
.I diff
|
||||
compares the contents of the two files
|
||||
.I from-file
|
||||
and
|
||||
.IR to-file .
|
||||
A file name of
|
||||
.B \-
|
||||
stands for
|
||||
text read from the standard input. As a special case,
|
||||
.B "diff \- \-"
|
||||
compares a copy of standard input to itself.
|
||||
|
||||
If
|
||||
.I from-file
|
||||
is a directory and
|
||||
.I to-file
|
||||
is not,
|
||||
.I diff
|
||||
compares the file in
|
||||
.I from-file
|
||||
whose file name is that of
|
||||
.IR to-file ,
|
||||
and vice versa. The non-directory file must not be
|
||||
.BR \- .
|
||||
|
||||
If both
|
||||
.I from-file
|
||||
and
|
||||
.I to-file
|
||||
are directories,
|
||||
.I diff
|
||||
compares corresponding files in both directories, in
|
||||
alphabetical order; this comparison is not recursive unless the
|
||||
.B \-r
|
||||
or
|
||||
.B \-\-recursive
|
||||
option is given.
|
||||
.I diff
|
||||
never
|
||||
compares the actual contents of a directory as if it were a file. The
|
||||
file that is fully specified may not be standard input, because standard
|
||||
input is nameless and the notion of ``file with the same name'' does not
|
||||
apply.
|
||||
|
||||
.B diff
|
||||
options begin with
|
||||
.BR \- ,
|
||||
so normally
|
||||
.I from-file
|
||||
and
|
||||
.I to-file
|
||||
may not begin with
|
||||
.BR \- .
|
||||
However,
|
||||
.B \-\-
|
||||
as an
|
||||
argument by itself treats the remaining arguments as file names even if
|
||||
they begin with
|
||||
.BR \- .
|
||||
.SS Options
|
||||
Below is a summary of all of the options that GNU
|
||||
.I diff
|
||||
accepts.
|
||||
Most options have two equivalent names, one of which is a single letter
|
||||
preceded by
|
||||
.BR \- ,
|
||||
and the other of which is a long name preceded by
|
||||
.BR \-\- .
|
||||
Multiple single letter options (unless they take an
|
||||
argument) can be combined into a single command line word:
|
||||
.B \-ac
|
||||
is
|
||||
equivalent to
|
||||
.BR "\-a \-c" .
|
||||
Long named options can be abbreviated to
|
||||
any unique prefix of their name. Brackets
|
||||
.RB ( [
|
||||
and
|
||||
.BR ] )
|
||||
indicate that an
|
||||
option takes an optional argument.
|
||||
.TP
|
||||
.BI \- lines
|
||||
Show
|
||||
.I lines
|
||||
(an integer) lines of context. This option does not
|
||||
specify an output format by itself; it has no effect unless it is
|
||||
combined with
|
||||
.B \-c
|
||||
or
|
||||
.BR \-u .
|
||||
This option is obsolete. For proper
|
||||
operation,
|
||||
.I patch
|
||||
typically needs at least two lines of context.
|
||||
.TP
|
||||
.B \-a
|
||||
Treat all files as text and compare them line-by-line, even if they
|
||||
do not seem to be text.

||||
.TP
|
||||
.B \-b
|
||||
Ignore changes in amount of white space.
|
||||
.TP
|
||||
.B \-B
|
||||
Ignore changes that just insert or delete blank lines.
|
||||
.TP
|
||||
.B \-\-brief
|
||||
Report only whether the files differ, not the details of the
|
||||
differences.
|
||||
.TP
|
||||
.B \-c
|
||||
Use the context output format.

||||
is not given.
|
||||
For proper operation,
|

||||
context.
|
||||
.TP
|
||||
.BI \-\-changed\-group\-format= format

both files in if-then-else format.

|
||||
.SH DESCRIPTION
|
||||
The
|
||||
.I diff3
|
||||
command compares three files and outputs descriptions
|
||||
of their differences.
|
||||
|
||||
The files to compare are
|
||||
.IR mine ,
|
||||
.IR older ,
|
||||
and
|
||||
.IR yours .
|
||||
At most one of these three file names may be
|
||||
.BR \- ,
|
||||
which tells
|
||||
.I diff3
|
||||
to read the standard input for that file.
|
||||
.SS Options
|
||||
Below is a summary of all of the options that GNU
|
||||
.I diff3
|
||||
accepts. Multiple single letter options (unless they take an argument)
|
||||
can be combined into a single command line argument.
|
||||
.TP
|
||||
.B \-a
|
||||
Treat all files as text and compare them line-by-line, even if they
|
||||

.SH NAME

sdiff \- find differences between two files and merge interactively
|

.SH SYNOPSIS
|
||||
.B sdiff
|
||||
.B -o
|
||||
outfile [options] from-file to-file
|
||||
.SH DESCRIPTION
|
||||
The
|
||||
.I sdiff
|
||||
command merges two files and interactively outputs the
|
||||
results to
|
||||
.IR outfile .
|
||||
|
||||
If
|
||||
.I from-file
|
||||
is a directory and
|
||||
.I to-file
|
||||
is not,
|
||||
.I sdiff
|
||||
compares the file in
|
||||
.I from-file
|
||||
whose file name is that of
|
||||
.IR to-file ,
|
||||
and vice versa.
|
||||
.I from-file
|
||||
and
|
||||
.I to-file
|
||||
may not both be
|
||||
directories.
|
||||
|
||||
.I sdiff
|
||||
options begin with
|
||||
.BR \- ,
|
||||
so normally
|
||||
.I from-file
|
||||
and
|
||||
.I to-file
|
||||
may not begin with
|
||||
.BR \- .
|
||||
However,
|
||||
.B \-\-
|
||||
as an
|
||||
argument by itself treats the remaining arguments as file names even if
|
||||
they begin with
|
||||
.BR \- .
|
||||
You may not use
|
||||
.B \-
|
||||
as an input file.
|
||||
|
||||
.I sdiff
|
||||
without
|
||||
.B \-o
|
||||
(or
|
||||
.BR \-\-output )
|
||||
produces a
|
||||
side-by-side difference. This usage is obsolete; use
|
||||
.B "diff \-\-side\-by\-side"
|
||||
instead.
|
||||
.SS Options
|
||||
Below is a summary of all of the options that GNU
|
||||
.I sdiff
|
||||
accepts.
|
||||
Each option has two equivalent names, one of which is a single
|
||||
letter preceded by
|
||||
.BR \- ,
|
||||
and the other of which is a long name
|
||||
preceded by
|
||||
.BR \-\- .
|
||||
Multiple single letter options (unless they take
|
||||
an argument) can be combined into a single command line argument. Long
|
||||
named options can be abbreviated to any unique prefix of their name.
|
||||
.TP
|
||||
.B \-a
|
||||
Treat all files as text and compare them line-by-line, even if they
|
||||
do not appear to be text.
|
||||
.TP
|
||||
.B \-b
|
||||
Ignore changes in amount of white space.
|
||||
.TP
|
||||
.B \-B
|
||||
Ignore changes that just insert or delete blank lines.
|
||||
.TP
|
||||
.B \-d
|
||||
Change the algorithm to perhaps find a smaller set of changes. This
|
||||
makes
|
||||
.I sdiff
|
||||
slower (sometimes much slower).
|
||||
.TP
|
||||
.B \-H
|
||||
Use heuristics to speed handling of large files that have numerous
|
||||
scattered small changes.

Expand tabs to spaces in the output, to preserve the alignment of tabs
|
||||
in the input files.
|

|
