fdupes option
According to the GitHub page https://github.com/adrianlopezroche/fdupes fdupes has a --time (or -t) option that lists the file times. The Cygwin version doesn't have this feature. It is not clear to me whether this is something to do with how cygwin was compiled or this is an option added after the current cygwin version (1.50-PR2-3; current version is 1.6.1). I would appreciate it if the maintainer would release a version that implements the -t option.

[ANNOUNCEMENT] multitail 6.5.0-1
multitail 6.5.0-1 is now available in Cygwin. This is a new upstream release. The author of multitail doesn't provide an up-to-date changelog, but there's a little bit of explanation on the project home page[1], and an older changelog[2]. MultiTail lets you view one or multiple files like the original tail program. The difference is that it creates multiple windows on your console (with ncurses). It can also: * Monitor wildcards: if another file matching the wildcard has a more recent modification date, it will automatically switch to that file. That way you can, for example, monitor a complete directory of files. * Merge 2 or more logfiles. * Use colors while displaying the logfiles (through regular expressions), for faster recognition of what is important and what not. * Filter lines (again with regular expressions) and has interactive menus for editing given regular expressions and deleting and adding windows. * Have windows with the output of shell scripts and other software. When viewing the output of external software, MultiTail can mimic the functionality of tools like 'watch' and such. Andrew E.

[ANNOUNCEMENT] stunnel 5.56-1
stunnel 5.56-1 is now available in Cygwin. This release includes minor bug fixes and documentation improvements. Please see the upstream changelog[1] for the full list. stunnel is a program that allows you to encrypt arbitrary TCP connections inside TLS (Transport Layer Security, the successor to Secure Sockets Layer (SSL)). stunnel can allow you to secure non-TLS-aware daemons and protocols (like POP, IMAP, LDAP, etc) by having stunnel provide the encryption, requiring no changes to the daemon's code.

Ah, yes, there's a problem. When listing /cygdrive, we're trying to do this as quick as possible. For network drives, we check if they are available using a function NetUseGetInfo, which only takes a few ms, even if the drive is unavailable. As soon as this function returns the state "disconnected", Cygwin skips the drive in /cygdrive. However, this function does not know anything about client side caching (CSC). To find out if the drive is available via CSC, the drive has to be opened and checked for filesystem information, which reflects the state that the filesystem is still available offline. The problem with this approach is, it would have to be called for each unavailable drive in /cygdrive. This takes multiple secs per drive. That's exacly what we tried to avoid when calling the aforementioned NetUseGetInfo function in the first place. Checking for a CSC-ed drive when disconnected would make /cygdrive listing very slow, just as in the old days... Corinna -- Corinna Vinschen Cygwin Maintainer signature.asc Description: PGP signature

That's not the point, actually. Setting up drives is always a Windows thingy. Cygwin just reads the configuration and tries to map it into a POSIX context. > Whether or not the device is available, there is a Z: drive mapping > maintained within Explorer, however the /cygdrive/z/ mount is only > available if the device is available. Right. Cygwin uses a simple mechanism to check the drives to show under /cygdrive. Basically it just calls the Win32 function GetLogicalDriveStrings(), then, for each drive, it checks the QueryDosDevice mapping. Right now it only accepts cdrom, floppy, harddrive, LanmanRedirector (SMB) and MRxNfs (NFS). All other drive types are treated as "no disk". This is fixable with probably not too much effort. > The problem is exhibited on: > > Windows 7 Professional Ver 6.1 Build 7601 Service Pack 1 Yeah, that's what I tried, too, as I wrote, besides W10. I'm still not seeing the assertion failure. I tried this with a "normal" mapping of the remote drive, as well as with a drive marked "available offline", to no avail. That's why *maybe* the drive type is part of the problem. Corinna -- Corinna Vinschen Cygwin Maintainer signature.asc Description: PGP signature

It would be nice to know what kind of drive this is. "cifs" in Cygwin means a remote drive, claiming to be NTFS, but not having the expected FS flags of a real NTFS.
