When I specify a directory with the --to-file option, and ask diff to compare multiple files with the corresponding files under the to-file directory, only the first file is diffed; a "No such file or directory" message is displayed for everything else.
Example: $ /bin/diff -s --to-file=tmp/ 012018.pdf ben.pdf Files 012018.pdf and tmp/012018.pdf are identical /bin/diff: tmp/: No such file or directory But running diff separately on the two files works: $ /bin/diff -s --to-file=tmp/ 012018.pdf Files 012018.pdf and tmp/012018.pdf are identical $ /bin/diff -s --to-file=tmp/ ben.pdf Files ben.pdf and tmp/ben.pdf are identical I'm reasonably sure this used to work earlier as I expected, but a quick search did not find any related discussions / bug reports. Could someone kindly confirm whether this is a bug or incorrect understanding on my part? Many thanks, Mandar.
