Most options have two equivalent names, one of which is a single letter preceded by ‘-’, and the other of which is a long name preceded by ‘--’. Multiple single letter options (unless they take an argument) can be combined into a single command line word: -ac is equivalent to -a -c. Long named options can be abbreviated to any unique prefix of their name. Brackets ([ and ]) indicate that an option takes an optional argument.

-a--text
Treat all files as text and compare them line-by-line, even if they do not seem to be text. See Binary Files and Forcing Text Comparisons.
-b--ignore-space-changeIgnore changes in amount of white space. See Suppressing Differences in Blank and Tab Spacing.
-B--ignore-blank-linesIgnore changes that just insert or delete blank lines. See Suppressing Differences Whose Lines Are All Blank.
--binaryRead and write data in binary mode. See Binary Files and Forcing Text Comparisons.
-cUse the context output format, showing three lines of context. See Context Format.
--color [=when] ¶Specify whether to use color for distinguishing different contexts, like header, added or removed lines. when may be omitted, or one of:
- none Do not use color
all. This is the default when no –color option is specified. auto Use color only if standard output is a terminal. always Always use color.
Specifying --color and no when is equivalent to --color=auto.
-C lines--context[=lines]Use the context output format, showing lines (an integer) lines of context, or three if lines is not given. See Context Format. For proper operation, patch typically needs least two lines of context.
For compatibility diff also supports an obsolete option syntax -lines that has effect when combined with -c, -p, or -u. New scripts should use -U lines (-C lines) instead.
--changed-group-format=formatUse format to output a line group containing differing lines from both files in if-then-else format. See Line Group Formats.
-d --minimalChange the algorithm perhaps find a smaller set of changes. This makes diff slower (sometimes much slower). See diff Performance Tradeoffs.
-D name--ifdef=nameMake merged ‘#ifdef’ format output, conditional on the preprocessor macro name. See Merging Files with If-then-else.
-e--edMake output that is a valid ed script. See ed Scripts.
-E--ignore-tab-expansionIgnore changes due to tab expansion. See Suppressing Differences in Blank and Tab Spacing.
-f--forward-edMake output that looks vaguely like an ed script but has changes in the order they appear in the file. See Forward ed Scripts.
-F regexp--show-function-line=regexpIn context and unified format, for each hunk of differences, show some of the last preceding line that matches regexp. See Showing Lines That Match Regular Expressions.
--from-file=fileCompare file to each operand; file may be a directory.
--helpOutput a summary of usage and then exit.
--horizon-lines=linesDo not discard the last lines lines of the common prefix and the first lines lines of the common suffix. See diff Performance Tradeoffs.
-i--ignore-caseIgnore changes in case; consider upper- and lower-case letters equivalent. See Suppressing Case Differences.
-I regexp--ignore-matching-lines=regexpIgnore changes that just insert or delete lines that match regexp. See Suppressing Differences Whose Lines All Match a Regular Expression.
--ignore-file-name-caseIgnore case when comparing file names. For example, recursive comparison of d to e might compare the contents of d/Init and e/inIt. At the top level, ‘diff d inIt’ might compare the contents of d/Init and inIt. See Comparing Directories.
-l--paginatePass the output through pr to paginate it. See Paginating diff Output.
-L label--label=labelUse label instead of the file name in the context format (see Context Format) and unified format (see Unified Format) headers. See RCS Scripts.
--left-columnPrint only the left column of two common lines in side by side format. See Controlling Side by Side Format.
--line-format=formatUse format to output all input lines in if-then-else format. See Line Formats.
-n--rcsOutput RCS-format diffs; like -f except that each command specifies the number of lines affected. See RCS Scripts.
-N--new-fileIf one file is missing, treat it as present but empty. See Comparing Directories.
--new-group-format=formatUse format to output a group of lines taken from just the second file in if-then-else format. See Line Group Formats.
--new-line-format=formatUse format to output a line taken from just the second file in if-then-else format. See Line Formats.
--no-dereferenceAct on symbolic links themselves instead of what they point to. Two symbolic links are deemed equal only when each points to precisely the same name.
--old-group-format=formatUse format to output a group of lines taken from just the first file in if-then-else format. See Line Group Formats.
--old-line-format=formatUse format to output a line taken from just the first file in if-then-else format. See Line Formats.
-p--show-c-functionShow which C function each change is in. See Showing C Function Headings.
--palette=paletteSpecify what color palette to use when colored output is enabled. It defaults to ‘rs=0:hd=1:ad=32:de=31:ln=36’ for red deleted lines, green added lines, cyan line numbers, bold header.
Supported capabilities are as follows.
SGR substring for added lines. The default is green foreground.
de=31 ¶SGR substring for deleted lines. The default is red foreground.
hd=1 ¶SGR substring for chunk header. The default is bold foreground.
ln=36 ¶SGR substring for line numbers. The default is cyan foreground.
-q--briefReport only whether the files differ, not the details of the differences. See Summarizing Which Files Differ.
-r--recursiveWhen comparing directories, recursively compare any subdirectories found. See Comparing Directories.
-s--report-identical-filesReport when two files are the same. See Comparing Directories.
-S file--starting-file=fileWhen comparing directories, start with the file file. This is used for resuming an aborted comparison. See Comparing Directories.
--speed-large-filesUse heuristics to speed handling of large files that have numerous scattered small changes. See diff Performance Tradeoffs.
--strip-trailing-crStrip any trailing carriage return the end of an input line. See Binary Files and Forcing Text Comparisons.
--suppress-common-linesDo not print common lines in side by side format. See Controlling Side by Side Format.
-t--expand-tabsExpand tabs to spaces in the output, to preserve the alignment of tabs in the input files. See Preserving Tab Stop Alignment.
-T--initial-tabOutput a tab rather than a space before the text of a line in normal or context format. This causes the alignment of tabs in the line to look normal. See Preserving Tab Stop Alignment.
--tabsize=columnsAssume that tab stops are set every columns (default 8) print columns. See Preserving Tab Stop Alignment.
--suppress-blank-emptySuppress any blanks before newlines when printing the representation of an empty line, when outputting normal, context, or unified format. See Omitting trailing blanks.
--to-file=fileCompare each operand to file; file may be a directory.
-uUse the unified output format, showing three lines of context. See Unified Format.
--unchanged-group-format=formatUse format to output a group of common lines taken from both files in if-then-else format. See Line Group Formats.
--unchanged-line-format=formatUse format to output a line common to both files in if-then-else format. See Line Formats.
--unidirectional-new-fileIf a first file is missing, treat it as present but empty. See Comparing Directories.
-U lines--unified[=lines]Use the unified output format, showing lines (an integer) lines of context, or three if lines is not given. See Unified Format. For proper operation, patch typically needs least two lines of context.
On older systems, diff supports an obsolete option -lines that has effect when combined with -u. POSIX 1003.1-2001 (see Standards conformance) does not allow this; use -U lines instead.
-v--versionOutput version information and then exit.
-w--ignore-all-spaceIgnore white space when comparing lines. See Suppressing Differences in Blank and Tab Spacing.
-W columns--width=columnsOutput most columns (default 130) print columns per line in side by side format. See Controlling Side by Side Format.
-x pattern--exclude=patternWhen comparing directories, ignore files and subdirectories whose basenames match pattern. See Comparing Directories.
-X file--exclude-from=fileWhen comparing directories, ignore files and subdirectories whose basenames match any pattern contained in file. See Comparing Directories.
-y--side-by-sideUse the side by side output format. See Controlling Side by Side Format.
-Z--ignore-trailing-spaceIgnore white space line end. See Suppressing Differences in Blank and Tab Spacing.
When using WC you Cannot specify all three options in the command line the same time?
When using wc, you cannot specify all three options (-l, -w and -c) in the command line the same time. The pipe operator can connect several commands on the same command line.Which of the following shells was the first UNIX command processor?
The first Unix shell was the Thompson shell, sh, written by Ken Thompson Bell Labs and distributed with Versions 1 through 6 of Unix, from 1971 to 1975.Is a computer language that uses English like expressions?
Syntax. COBOL has an English-like syntax, which is used to describe nearly everything in a program. For example, a condition can be expressed as x IS GREATER THAN y or more concisely as x GREATER y or x > y .Can you use the vi editor to create script files?
You can use the vi editor to create script files. A popular use of pr is to convert lowercase characters to uppercase characters. Tải thêm tài liệu liên quan đến nội dung bài viết The ____ option of the diff command shows lines surrounding the line that differs.
