Not generate a carriage return at the end of each output line. On such systems, 'diff' normally ignores these carriage returns on input and generates them at the end of each output line, but with the '-binary' option 'diff' treats each carriage return as just another input character, and does However, many personal computer operating systems represent the end ofĪ line with a carriage return followed by a newline. This option has no effect on a Posix-compliant system like GNU or traditional Unix. Use the '-binary' option to force 'diff' to read and write binary data instead. In operating systems that distinguish between text and binary files, 'diff' normally reads and writes all data as text. These options can accumulate for example, you can ignore changes in both white space and alphabetic case. 'diff' also provides ways to suppress differences in alphabetic case or in lines that match a regular expression that you provide. Most commonly, such differences are changes in the amount of white space between words or lines. It also provides ways to suppress certain kinds of differences that are not important to you. GNU 'diff' can show whether files are different without detailing the differences. If both from-file and to-file are directories, diff compares corresponding files in both directories, in alphabetical order this comparison is not recursive unless the -r or -recursive option is given. If from-file is a directory and to-file is not, diff compares the file in from-file whose file name is that of to-file, and vice versa. A file name of - stands for text read from the standard input. In the simplest case, diff compares the contents of the two files from-fileand to-file. %c'\OOO' The character with octal code OOO %l contents of line, excluding any trailing newline LETTERs are as follows for new group, lower case for old group: Similar, but format LTYPE input lines with LFMT. Similar, but format all input lines with LFMT. Ignore changes whose lines all match REGEXP. Similar, but format GTYPE input groups with GFMT. Output merged file to show '#ifdef NAME' diffs. FILE1 can be a directory.Ĭompare all operands to FILE2. Output at most NUM (default 130) print columns.Įxclude files that match any pattern in FILE.Ĭompare FILE1 to all operands. Output NUM (default 3) lines of unified context. Start with FILE when comparing directories.Īssume large files and many scattered small changes. Recursively compare any subdirectories found. Pass the output through 'pr' to paginate it. Output only the left column of common lines. Ignore case differences in file contents. Keep NUM lines of the common prefix and suffix. Try hard to find a smaller set of changes. Output NUM (default 3) lines of copied context. Ignore changes whose lines are all blank. Ignore changes in the amount of white space. If -from-file or -to-file is given, there are no restrictions on FILES. FILES are 'FILE1 FILE2' or 'DIR1 DIR2' or 'DIR FILE.' or 'FILE. Multiple single letter options (unless they take an argument) can be combined into a single command line word: so '-ac' is equivalent to '-a -c'. For files that are identical,ĭiff normally produces no output for binary (non-text) files, diff normally Display the differences between two files, or each correspondingĮach set of differences is called a "diff" or "patch".
