[rrc@Llawyr ComandosDeLaTerminal]$ diff diff --help Usage: diff [OPTION]... FILES Compare FILES line by line.

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

     --normal                  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
     --left-column             output only the left column of common lines
     --suppress-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
     --tabsize=NUM             tab stops every NUM (default 8) print columns
     --suppress-blank-empty    suppress space or tab before empty output lines
 -l, --paginate                pass output through 'pr' to paginate it
 -r, --recursive                 recursively compare any subdirectories found
     --no-dereference            don't follow symbolic links
 -N, --new-file                  treat absent files as empty
     --unidirectional-new-file   treat absent first files as empty
     --ignore-file-name-case     ignore case when comparing file names
     --no-ignore-file-name-case  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
     --from-file=FILE1           compare FILE1 to all operands;
                                   FILE1 can be a directory
     --to-file=FILE2             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 where lines are all blank
 -I, --ignore-matching-lines=RE  ignore changes where all lines match RE
 -a, --text                      treat all files as text
     --strip-trailing-cr         strip trailing carriage return on input
 -D, --ifdef=NAME                output merged file with '#ifdef NAME' diffs
     --GTYPE-group-format=GFMT   format GTYPE input groups with GFMT
     --line-format=LFMT          format all input lines with LFMT
     --LTYPE-line-format=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
     %[-][WIDTH][.[PREC]]{doxX}LETTER  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
     %(A=B?T:E)  if A equals B then T else E
   LFMT (only) may contain:
     %L  contents of line
     %l  contents of line, excluding any trailing newline
     %[-][WIDTH][.[PREC]]{doxX}n  printf-style spec for input line number
   Both GFMT and LFMT may contain:
     %%  %
     %c'C'  the single character C
     %c'\OOO'  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
     --horizon-lines=NUM  keep NUM lines of the common prefix and suffix
     --speed-large-files  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.
