each with a line number (or range) in path2. After the line giving the type of change, diff displays
the deleted or added lines, prefixing lines from path1 with < and lines from path2 with >.
When you call the command as diffh, it automatically uses the -h option.
When you call it as bdiff, diff computes the differences in chunks of n lines (default 3999). This
lets you process arbitrarily large files and generally produces less output than the -h option.
The vdiff32 command is a graphical version of diff, giving you the ability to compare and view
files from a graphical user interface. Complete instructions on using vdiff32 are available
through its online help feature.
Options
-B
-b
-C n
-c[n]
uses diffb to compare the files when binary files are detected.
ignores white space at the end of each line (except the newline) and treats all consecutive
strings of white space elsewhere in a line as equivalent (effectively, reducing all strings of
white space to a single space for the purpose of comparing lines). For example if one file
contained a string of three spaces and a tab at a given location while the other file contained
a string of two spaces at the same location, diff would not report this as a difference.
shows n lines of context before and after each change. diff marks lines removed from
path1 with -, lines added to path2 with + and lines changed in both files with !. This option
conflicts with the -e and -f options.
is equivalent to -C n, but n is optional. The default value for n is 3. This option conflicts with
the -e and -f options.
-Difname
displays output that is the appropriate input to the C preprocessor to generate the contents
of path2 when ifname is defined, and the contents of path1 when ifname is not defined.
-e
-f
writes out a script of commands for the ed text editor that converts path1 to path2. diff
sends the output to the standard output. This option conflicts with the -m, -c, and -C
options.
