where 'a' means: add lines n3 thru n4 from newfile at location n1 in newfile; 'd' 
means: delete lines n1 thru n2 from newfile, next line is n3 in newfile; and 'c' 

means: change lines n1 thru n2 in newfile to lines n3 thru n4 in newfile Identical 
pairs where n1=n2 or n3=n4 are abbreviated as a single number. Following each of 

the [adc] lines comes each of the lines effected. Lines preceded by '<' are from 
oldfile, those preceded by '>' are from newfile. 

The options for Diff are: 

-b

: Ignore trailing whitespace and treat sequences of embedded whitespace as being 

equal. 

-i:

 Ignore leading whitespace. 

-d

: Treat files as if they were binary, only reporting if they are different. 

-t

: Treat files as if they were text, even if default autodetection claims they are 

binary. 

-v

: Report on each file that it processes, not just the ones with differences. 

-o

: Colorize output with the default colors (black, white, light cyan, and yellow), just 

as '-O 0fbe' would. 

-O <colors>

: Colorize output with the specified single-character hex colors: 

background, normal text, old text, and new text. The colors are: black = 0, blue = 1, 
green = 2, cyan = 3, red = 4, magenta = 5, brown = 6, lightgray = 7, darkgray = 8, 

lightblue = 9, lightgreen = A, lightcyan = B, lightred = C, lightmagenta = D, yellow 
= E, white = F. 

-?

: Display program description. 

Note: If the environment variable DIFF exists, its value is used to establish default 

options. 

Note: You can override an option that was specified in the environment variable by 

following the option with a minus '-' sign. For example, to turn off the -b option, 
specify -b-.
