Syncdir -- Synchronize two directories

(4/16/2002) Version 1.5.3 released. [What's New]

When you install PC-UNIX on your laptop, it is convenient to duplicate (a part of) your home directory on the laptop. There is, however, another problem to make consistency between two home directories.

Syncdir helps the wasteful work and makes consistency based on modification time. Main features are

• Syncdir can UNDO(*1).
• You can specify making a diff file, backing up, or deleting for old file to be updated.
• There are several kind of synchronizations,
  1. replacing by new file,
  2. making priority over either directory (or even both directories!).
  Moreover, there is a mode to recognize automatically which directory is new.
• You can specify filenames ignored in the synchronization process.
• You can synchronize only recently modified files.
• You don't need to register a set of files in advance unlike Briefcase software on Win95.

Diffdir compares two directories using diff(1). Unlike diff -r, you can specify ignored filenames and directories.

I'm sure to work on FreeBSD, Linux, Solaris, SunOS, Digital UNIX and IRIX. however I guess it can work on a large majority of UNIXes.

(*1) To undo, syncdir does file operations in the reverse order that the last syncdir does since syncdir does not register a set of files. It is assumed there is no file operation that violates undoing after the last syncdir. Before version 1.3.7, the modification time of files restored by diff files is the time of restoring, so the succeeding syncdir results in unexpected updating new files by the corresponding old files. However, after version 1.3.8, this problem is fixed by restoring the modification time also.
