DESCRIPTION
|
||
the same name, when file1 and file2 are both directories" difference
|
||
encountered"
|
||
|
||
Diff compares two files and generates a list of lines telling how the two
|
||
files differ. Lines may not be longer than 128 characters. If the two
|
||
arguments on the command line are both directories, diff recursively
|
||
steps through all subdirectories comparing files of the same name. If a
|
||
file name is found only in one directory, a diagnostic message is written
|
||
to stdout. A file that is of either block special, character special or
|
||
FIFO special type, cannot be compared to any other file. On the other
|
||
hand, if there is one directory and one file given on the command line,
|
||
diff tries to compare the file with the same name as file in the
|
||
directory directory.
