I was having issues with comparison of two large csv files that I came across fc comparision command of Microsoft DOS. fc is a command line program that compares multiple files and outputs the differences between them
The syntax of fc Command and results of execution of fc with different arguments is shown below:
Syntax for fc command:
fc filename1 filename 2 [Parameter for comparision type] >Log File Path
where filename1 and filename2 are paths of the two files to be compared .
LogFilePath is path for saving result log
Commonly used Parameters are as described below:
/a : fc displays only the first and last line for each set of differences.
/b : Compares the files in binary mode.
/c : Ignores the case of letters.
/l : Fc compares the two files line by line and attempts to resynchronize the files after finding a mismatch.
/lbn : Sets the n number of lines for the internal line buffer.
/n : Displays the line numbers during an ASCII comparison.
