                              FC

The FC external command compares two files.  FC is useful to determine how 
.EXE files differ, or in what ways text files differ (you are reading a text 
file now). Not all DOS systems have the FC command.

FC[/A][/B][/C][/L][/W][/T][/N][/LB buf] [/lines] 
    [d1:][pathname1]filename1[.ext1] [d2:][pathname2]filename2[.ext2]
     \____________________________/   \____________________________/

filename1 is the source file to be compared. A [d1:][pathname1] and .ext1
    ext1 may be specified if necessary. 

filename2 is the target file to be compared. A [d2:][pathname2] and .ext2
    may be specified if necessary. 

[/A] Abbreviate the list of differences in a text comparison, rather than
    listing all of them. When blocks of text differ, only the first and last
    lines of the blocks will be listed.

[/B] Do an exact comparison a character at a time. If differences are found, 
    no allowance for inserted or deleted characters is made. /B is assumed 
    when .BIN, .COM, .EXE. .LIB, .OBJ, and .SYS files are compared.

[/C] When comparing text files, ignore differences in the case of the
    alphabetic characters being compared.

[/L] Text comparison a line at a time. If differences are found, an 
    attempt to make allowances for inserted or deleted lines is made.
    
[/T] Tab characters (tabs set every 8 columns) are NOT the same as spaces 
    in text comparisons.

[/W] White space -- sequences of tab characters and spaces are treated
    as if they were a single space in doing text comparisons.

[/N] Display line numbers of differences in the text files being compared.

[/LB buf] Buffer <buf> lines of text in each file rather than the
    default (100 lines) when comparing text files.

[/lines] <lines> specifies the minimum number of lines of text that
    must match after a difference to report another difference. The 
    default is two lines.
