Does Cygwin have a tool like lsof which can list which files or
directories are in use by a Windows process?
You can check these things yourself using the Cygwin Search Packages page:
https://cygwin.com/packages/
type "usr/bin/lsof" and hit Enter:
https://cygwin.com/cgi-bin2/package-grep.cgi?grep=usr%2Fbin%2Ffuser
Search Results
Found 0 matches for usr/bin/lsof
and the same on the command line:
$ cygcheck -p usr/bin/lsof
Found 0 matches for usr/bin/lsof
but Cygwin does have fuser:
$ cygcheck -p usr/bin/fuser
Found 6 matches for usr/bin/fuser

and Windows has openfiles:
$ cmd /c help openfiles
OPENFILES /parameter [arguments]
Description:
Enables an administrator to list or disconnect files and folders
that have been opened on a system.
Parameter List:
/Disconnect Disconnects one or more open files.
/Query Displays files opened locally or from shared
folders.
/Local Enables / Disables the display of local open files.
/? Displays this help message.
Examples:
OPENFILES /Disconnect /?
OPENFILES /Query /?
OPENFILES /Local /?
Thank you.
But neither openfiles or fuser seem to work in this case, even if I
have a file open in my bash shell, and call fuser in the same bash
script:
bash -c 'command exec {n}</mynfsmount/myfile.txt ; echo "fd=$n" ;
fuser -a /mynfsmount ; true'
gives
fd=10
/mynfsmount:
(no processes listed, which might be correct, as maybe a non cygwin
process has that file open)
I use it to tell me when build processes close their logs.
Currently on X (lightly sanitized):
$ fuser -av ~/.xsession-errors
