sdiff

side-by-side merge of file differences

TLDR

Compare 2 files

>_ sdiff [path/to/file1] [path/to/file2]
copy

Compare 2 files, ignoring all tabs and whitespace

>_ sdiff -W [path/to/file1] [path/to/file2]
copy

Compare 2 files, ignoring whitespace at the end of lines

>_ sdiff -Z [path/to/file1] [path/to/file2]
copy

Compare 2 files in a case-insensitive manner

>_ sdiff -i [path/to/file1] [path/to/file2]
copy

Compare and then merge, writing the output to a new file

>_ sdiff -o [path/to/merged_file] [path/to/file1] [path/to/file2]
copy

SYNOPSIS

sdiff [OPTION]... FILE1 FILE2

DESCRIPTION

Side-by-side merge of differences between FILE1 and FILE2. Mandatory arguments to long options are mandatory for short options too. -o, --output=FILE operate interactively, sending output to FILE -i, --ignore-case consider upper- and lower-case to be the same -E, --ignore-tab-expansion ignore changes due to tab expansion -Z, --ignore-trailing-space ignore white space at line end -b, --ignore-space-change ignore changes in the amount of white space -W, --ignore-all-space ignore all white space -B, --ignore-blank-lines ignore changes whose lines are all blank -I, --ignore-matching-lines=RE ignore changes all whose lines match RE --strip-trailing-cr strip trailing carriage return on input -a, --text treat all files as text -w, --width=NUM output at most NUM (default 130) print columns -l, --left-column output only the left column of common lines -s, --suppress-common-lines do not output common lines -t, --expand-tabs expand tabs to spaces in output --tabsize=NUM tab stops at every NUM (default 8) print columns -d, --minimal try hard to find a smaller set of changes -H, --speed-large-files assume large files, many scattered small changes --diff-program=PROGRAM use PROGRAM to compare files --help display this help and exit -v, --version output version information and exit If a FILE is '-', read standard input. Exit status is 0 if inputs are the same, 1 if different, 2 if trouble.
