diff3 - compare three files line by line




   Compare three files line by line.

   Mandatory  arguments  to  long  options are mandatory for short options

   -A, --show-all
          output all changes, bracketing conflicts

   -e, --ed
          output ed script incorporating changes from OLDFILE to  YOURFILE
          into MYFILE

   -E, --show-overlap
          like -e, but bracket conflicts

   -3, --easy-only
          like -e, but incorporate only nonoverlapping changes

   -x, --overlap-only
          like -e, but incorporate only overlapping changes

   -X     like -x, but bracket conflicts

   -i     append 'w' and 'q' commands to ed scripts

   -m, --merge
          output  actual  merged file, according to -A if no other options
          are given

   -a, --text
          treat all files as text

          strip trailing carriage return on input

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

          use PROGRAM to compare files

   -L, --label=LABEL
          use LABEL instead of file name (can  be  repeated  up  to  three

   --help display this help and exit

   -v, --version
          output version information and exit

   The  default  output format is a somewhat human-readable representation
   of the changes.

   The -e, -E, -x, -X (and corresponding long) options cause an ed  script
   to be output instead of the default.

   Finally,  the  -m  (--merge)  option  causes  diff3  to  do  the  merge
   internally and output the actual merged file.  For unusual input,  this
   is more robust than using ed.

   If a FILE is '-', read standard input.  Exit status is 0 if successful,
   1 if conflicts, 2 if trouble.
