GNU diff utilities:
|
|
|
|
You can use the `diff' command to show differences between two
|
|
files, or each corresponding file in two directories. `diff' outputs
|
|
differences between files line by line in any of several formats,
|
|
selectable by command line options. This set of differences is often
|
|
called a "diff" or "patch". For files that are identical, `diff'
|
|
normally produces no output; for binary (non-text) files, `diff'
|
|
normally reports only that they are different.
|
|
|
|
You can use the `cmp' command to show the offsets and line numbers
|
|
where two files differ. `cmp' can also show all the characters that
|
|
differ between the two files, side by side.
|
|
|
|
You can use the `diff3' command to show differences among three
|
|
files. When two people have made independent changes to a common
|
|
original, `diff3' can report the differences between the original and
|
|
the two changed versions, and can produce a merged file that contains
|
|
both persons' changes together with warnings about conflicts.
|
|
|
|
You can use the `sdiff' command to merge two files interactively.
