Displaying the differences between two or more sets of data, file comparison tools can make computing simpler, and more efficient by focusing on new data and ignoring what did not change. Generically known as a diff [ 1 ] after the Unix diff utility , there are a range of ways to compare data sources and display the results.
The difference is an exact number of quarters of an hour up to 95 (same minutes modulo 15 and seconds) if the file was transported across zones; there is also a one-hour difference within a single zone caused by the transition between standard time and daylight saving time (DST). Some, but not all, file comparison and synchronisation software ...
In computing, the utility diff is a data comparison tool that computes and displays the differences between the contents of files. Unlike edit distance notions used for other purposes, diff is line-oriented rather than character-oriented, but it is like Levenshtein distance in that it tries to determine the smallest set of deletions and insertions to create one file from the other.
In computing, fc (File Compare) is a command-line program in DOS, IBM OS/2 and Microsoft Windows operating systems, that compares multiple files and outputs the differences between them. [2] [3] It is similar to the Unix commands comm, cmp and diff.
tkdiff uses colors to suggest differences between files and within shared lines. tkdiff is a graphical diff viewer based on the Tk framework. [1] It is capable of inter-operating with source-control systems like CVS and Subversion to show the differences between the local copy and the repository version.
Displaying the differences between two or more sets of data, file comparison tools can make computing simpler, and more efficient by focusing on new data and ignoring what did not change. Generically known as a diff [ 18 ] after the Unix diff utility , there are a range of ways to compare data sources and display the results.
Show differences between any two files, or any two sets of files. The command is available in MS-DOS versions 3.3 through 5 and IBM PC DOS releases 1 through 5. [1]
The customizable rules control which differences between two files should be flagged as such. A set of predefined rules is included for the comparison of common file types, such as C++ source code, XML, and HTML files. [6] Steve Gibson of GRC described it as "a really cool...very smart Windows-based source comparison tool." [7]
