-.Sh NAME
-.Nm cmp
-.Nd compare two files
-.Sh SYNOPSIS
-.Nm cmp
-.Op Fl l | Fl s
-.Ar file1 file2
-.Op Ar skip1 Op Ar skip2
-.Sh DESCRIPTION
-The cmp utility compares two files of any type and writes the results
-to the standard output.
-By default,
-.Nm
-is silent if the files are the same; if they differ, the byte
-and line number at which the first difference occurred is reported.
-.Pp
-Bytes and lines are numbered beginning with one.
-.Pp
-The following options are available:
-.Bl -tag -width flag
-.It Fl l
-Print the byte number (decimal) and the differing
-byte values (octal) for each difference.
-.It Fl s
-Print nothing for differing files; return exit
-status only.
-.El
-.Pp
-The optional arguments
-.Ar skip1
-and 
-.Ar skip2
-are the byte offsets from the beginning of
-.Ar file1
-and
-.Ar file2 ,
-respectively, where the comparison will begin.
-The offset is decimal by default, but may be expressed as an hexadecimal
-or octal value by preceding it with a leading ``0x'' or ``0''.
-.Pp
-The
-.Nm cmp
-utility exits with one of the following values:
-.Bl -tag -width 4n
-.It 0
-The files are identical.
-.It 1
-The files are different; this includes the case
-where one file is identical to the first part of
-the other.
-In the latter case, if the
-.Fl s
-option has not been specified,
-.Nm cmp
-writes to standard output that EOF was reached in the shorter
-file (before any differences were found).
-.It >1
-An error occurred.
-.El
-.Sh SEE ALSO
-.Xr diff 1 ,
-.Xr diff3 1
-.Sh STANDARDS
-The
-.Nm cmp
-utility is expected to be
-.St -p1003.2
-compatible.

-.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

-Treat all files as text and compare them line-by-line, even if they
-do not seem to be text.

-.TP
-.BI \-\-changed\-group\-format= format
-Use
-.I format
-to output a line group containing differing lines from
-both files in if-then-else format.

-.B \-d
-Change the algorithm to perhaps find a smaller set of changes.  This makes
-.I diff

-.SH NAME
-diff3 \- find differences between three files
-.SH SYNOPSIS
-.B diff3
-[options] mine older yours
-.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
-do not appear to be text.
-.TP
-.B \-A
-Incorporate all changes from
-.I older
-to
-.I yours
-into
-.IR mine ,
-surrounding all conflicts with bracket lines.
-.TP
-.B \-B
-Old behavior of -A.  Shows non-conflicts.
-.TP
-.B \-e
-Generate an
-.I ed
-script that incorporates all the changes from
-.I older
-to
-.I yours
-into
-.IR mine .
-.TP
-.B \-E
-Like
-.BR \-e ,
-except bracket lines from overlapping changes' first
-and third files.
-With
-.BR \-e ,
-an overlapping change looks like this:
-.sp
-.nf
-<<<<<<< \fImine\fP
-lines from \fImine\fP
-=======
-lines from \fIyours\fP
->>>>>>> \fIyours\fP
-.fi
-.TP
-.B \-\-ed
-Generate an

-to
-.I yours
-into

-.TP
-.B \-\-easy\-only
-Like

-except output only the nonoverlapping changes.
-.TP
-.B \-i
-Generate
-.B w
-and
-.B q
-commands at the end of the
-.I ed
-script for System V compatibility.  This option must be combined with
-one of the
-.B \-AeExX3
-options, and may not be combined with
-.BR \-m .
-.TP
-.B \-\-initial\-tab
-Output a tab rather than two spaces before the text of a line in normal format.
-This causes the alignment of tabs in the line to look normal.
-.TP
-.BI "\-L " label

-.TP
-.BI \-\-label= label
-Use the label
-.I label
-for the brackets output by the
-.BR \-A ,
-.B \-E
-and
-.B \-X
-options.  This option may be given up to three
-times, one for each input file.  The default labels are the names of
-the input files.  Thus
-.B "diff3 \-L X \-L Y \-L Z \-m A B C"
-acts like
-.BR "diff3 \-m A B C ,
-except that the output looks like it came from
-files named
-.BR X ,
-.B Y
-and
-.B Z
-rather than from files
-named
-.BR A ,
-.B B
-and
-.BR C .
-.TP
-.B \-m
-.br
-.ns
-.TP
-.B \-\-merge
-Apply the edit script to the first file and send the result to standard
-output.  Unlike piping the output from
-.I diff3
-to
-.IR ed ,
-this
-works even for binary files and incomplete lines.
-.B \-A
-is assumed
-if no edit script option is specified.
-.TP
-.B \-\-overlap\-only
-Like
-.BR \-e ,
-except output only the overlapping changes.
-.TP
-.B \-\-show\-all
-Incorporate all unmerged changes from

-Like
-.BR \-e ,
-except bracket lines from overlapping changes' first

-.TP
-.B \-T
-Output a tab rather than two spaces before the text of a line in normal format.
-This causes the alignment of tabs in the line to look normal.

-Treat all files as text and compare them line-by-line, even if they

-.B \-\-version
-Output the version number of
