diff - compare files line by line


diff [OPTION]... FILES


Compare FILES line by line.

Mandatory arguments to long options are mandatory for short options too.

output a normal diff (the default)

-q, --brief
report only when files differ

-s, --report-identical-files
report when two files are the same

-c, -C NUM, --context[=NUM]
output NUM (default 3) lines of copied context

-u, -U NUM, --unified[=NUM]
output NUM (default 3) lines of unified context

-e, --ed
output an ed script

-n, --rcs
output an RCS format diff

-y, --side-by-side
output in two columns

-W, --width=NUM
output at most NUM (default 130) print columns

output only the left column of common lines

do not output common lines

-p, --show-c-function
show which C function each change is in

-F, --show-function-line=RE
show the most recent line matching RE

--label LABEL
use LABEL instead of file name (can be repeated)

-t, --expand-tabs
expand tabs to spaces in output

-T, --initial-tab
make tabs line up by prepending a tab

tab stops every NUM (default 8) print columns

suppress space or tab before empty output lines

-l, --paginate
pass output through `pr' to paginate it

-r, --recursive
recursively compare any subdirectories found

-N, --new-file
treat absent files as empty

treat absent first files as empty

ignore case when comparing file names

consider case when comparing file names

-x, --exclude=PAT
exclude files that match PAT

-X, --exclude-from=FILE
exclude files that match any pattern in FILE

-S, --starting-file=FILE
start with FILE when comparing directories

compare FILE1 to all operands; FILE1 can be a directory

compare all operands to FILE2; FILE2 can be a directory

-i, --ignore-case
ignore case differences in file contents

-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 whose lines all match RE

-a, --text
treat all files as text

strip trailing carriage return on input

-D, --ifdef=NAME
output merged file with `#ifdef NAME' diffs

format GTYPE input groups with GFMT

format all input lines with LFMT

format LTYPE input lines with LFMT

These format options provide fine-grained control over the output

of diff, generalizing -D/--ifdef.

LTYPE is `old', `new', or `unchanged'.
GTYPE is LTYPE or `changed'.

GFMT (only) may contain:

%< lines from FILE1

%> lines from FILE2

%= lines common to FILE1 and FILE2

printf-style spec for LETTER

LETTERs are as follows for new group, lower case for old group:

F first line number

L last line number

N number of lines = L-F+1

E F-1

M L+1

if A equals B then T else E

LFMT (only) may contain:

%L contents of line

%l contents of line, excluding any trailing newline

printf-style spec for input line number

Both GFMT and LFMT may contain:

%% %

%c'C' the single character C

the character with octal code OOO

C the character C (other characters represent themselves)

-d, --minimal
try hard to find a smaller set of changes

keep NUM lines of the common prefix and suffix

assume large files and many scattered small changes

--help display this help and exit

-v, --version
output version information and exit

FILES are `FILE1 FILE2' or `DIR1 DIR2' or `DIR FILE...' or `FILE... DIR'. If --from-file
or --to-file is given, there are no restrictions on FILE(s). If a FILE is `-', read
standard input. Exit status is 0 if inputs are the same, 1 if different, 2 if trouble.
