file compare command

July 7, 2016

You can use the Windows command fc (standing for file compare) to detect differences between two text files.


If you have three text files like these in a folder:



 You can run the fc commands below to 


a.  show any differences between the two files:


fc "C:\foofolder3\test1.txt" "C:\foofolder3\test2.txt"


 . . .  and the complete differences will be shown. 


b. show when two files are identical


fc "C:\foofolder3\test1.txt" "C:\foofolder3\test2.txt"


. . . notice since these files are the same you get the message, "no differences encountered"



c.  a command with /LBn , where n = a number of different lines in the two files after which you want the comparison to cease. 


fc /LB1 "C:\foofolder3\test1.txt" "C:\foofolder3\test2.txt"
