CUT-DIFF(1) Cutter's manual CUT-DIFF(1)
NAME
cut-diff - show difference between 2 files with color
SYNOPSIS
cut-diff [option ...] file1 file2
DESCRIPTION
cut-diff is a diff command that uses diff feature in Cutter. It shows difference with color.
It's recommended that you use a normal diff(1) when you want to use with patch(1) or you don't need color.
OPTIONS
--version
cut-diff shows its own version and exits.
-c [yes|true|no|false|auto], --color=[yes|true|no|false|auto]
If 'yes' or 'true' is specified, cut-diff uses colorized output by escape sequence. If 'no' or 'false' is specified, cut-diff never
use colorized output. If 'auto' or the option is omitted, cut-diff uses colorized output if available.
The default is auto.
-u, --unified
cut-diff uses unified diff format.
--context-lines=LINES
Shows diff context around LINES.
All lines are shown by default. When unified diff format is used, 3 lines are shown by default.
--label=LABEL, -L=LABEL
Uses LABEL as a header label. The first--label option value is used as file1's label and the second --label option value is used
asfile2's label.
Labels are the same as file names by default.
EXIT STATUS
The exit status is 0 for success, non-0 otherwise.
TODO: 0 for non-difference, 1 for difference and non-0 for errors.
EXAMPLE
In the following example, cut-diff shows difference between file1 and file2:
% cut-diff file1 file2
In the following example, cut-diff shows difference between file1 and file2 with unified diff format:
% cut-diff -u file1 file2
