Comp

Compares the contents of two files or sets of files byte by byte.

Comp can compare files on the same drive or on different drives, and in the same directory or in different directories. As comp compares the files, it displays their locations and file names.

comp [data1] [data2] [/d] [/a] [/l] [/n=number] [/c]

Parameters

data1

Specifies the location and name of the first file or set of files you want to compare. You can use wildcard characters (* and ?) to specify multiple files.

data2

Specifies the location and name of the second file or set of files you want to compare. You can use wildcard characters (* and ?) to specify multiple files.

/d

Displays differences in decimal format. (The default format is hexadecimal.)

/a

Displays differences as characters.

/l

Displays the number of the line on which a difference occurs, instead of displaying the byte offset.

/n=number

Compares the first number of lines of both files, even if the files are different sizes.

/c

Performs a comparison that is not case-sensitive.
