NAME
sdiff - side-by-side diff
SYNOPSIS
sdiff [-abdilstHW] [-I regexp] [-o outfile] [-w width] file1 file2
DESCRIPTION
sdiff displays two files side by side, with any differences between the
two highlighted as follows: new lines are marked with `>'; deleted lines
are marked with `<'; and changed lines are marked with `|'.
sdiff can also be used to interactively merge two files, prompting at
each set of differences. See the -o option for an explanation.
The options are:
-l --left-column
Only print the left column for identical lines.
-o --output outfile
Interactively merge file1 and file2 into outfile. In this mode,
the user is prompted for each set of differences. See EDITOR and
VISUAL, below, for details of which editor, if any, is invoked.
The commands are as follows:
l | 1 Choose left set of diffs.
r | 2 Choose right set of diffs.
s Silent mode - identical lines are not printed.
v Verbose mode - identical lines are printed.
e Start editing an empty file, which will be merged into
outfile upon exiting the editor.
e l Start editing file with left set of diffs.
e r Start editing file with right set of diffs.
e b Start editing file with both sets of diffs.
q Quit sdiff.
-s --suppress-common-lines
Skip identical lines.
-w --width width
Print a maximum of width characters on each line. The default is
130 characters.
Options passed to diff(1) are:
-a --text
Treat file1 and file2 as text files.
Ignore line changes matching regexp. All lines in the change
must match regexp for the change to be ignored.
-i --ignore-case
Do a case-insensitive comparison.
-t --expand-tabs
Expand tabs to spaces.
-W --ignore-all-space
Ignore all spaces.
-B --ignore-blank-lines
Ignore blank lines.
-E --ignore-tab-expansion
Treat tabs and eight spaces as the same.
-t --ignore-tabs
Ignore tabs.
-H --speed-large-files
Assume scattered small changes in a large file.
--ignore-file-name-case
Ignore the case of file names.
--no-ignore-file-name-case
Do not ignore file name case.
--strip-trailing-cr
Skip identical lines.
--tabsize NUM
Change the size of tabs (default is 8.)
ENVIRONMENT
EDITOR, VISUAL
Specifies an editor to use with the -o option. If both EDITOR
and VISUAL are set, VISUAL takes precedence. If neither EDITOR
nor VISUAL are set, the default is vi(1).
TMPDIR Specifies a directory for temporary files to be created. The
default is /tmp.

CAVEATS
Tabs are treated as anywhere from one to eight characters wide, depending
on the current column. Terminals that treat tabs as eight characters
wide will look best.
