(I am a UNIX senior admin, but have VERY few knowledge on Windows)
UNIX does not support hard links on directories (in opposite to Windows?).
I found:
/: uname -a
CYGWIN_NT-10.0 W10dev 3.1.2(0.340/5/3) 2019-12-21 15:25 x86_64 Cygwin
/: ls -ldi /bin /usr/bin
281474976929589 drwxr-xr-x+ 1 admin None 0 Jan 29 16:01 /bin
281474976929589 drwxr-xr-x+ 1 admin None 0 Jan 29 16:01 /usr/bin
/: ls -ldi /lib /usr/lib
281474976929595 drwxr-xr-x+ 1 admin None 0 Jun 15 2018 /lib
281474976929595 drwxr-xr-x+ 1 admin None 0 Jun 15 2018 /usr/lib
Are this directory hard links?
Their content seems to be identical.
(How) can I find out with Cygwin which directories are hard links?
I could run "find / -xdev -type d -printf "%i %p\n" and look for same
inodes.
Is there a better methode?
/: find / -xdev -type d -printf "%i %p\n" | perl -wne 'push @{$i{$1}},$2 if
/^(\d+) (.+)/; END { foreach $n (keys %i) { @f = @{$i{$n}}; print "$n: @f\n" if
scalar(@f) > 1} }' | sort -n | head
2: /proc /cygdrive
281474976929589: /bin /usr/bin
281474976929595: /lib /usr/lib
281474976935384: /lib/pkcs11 /usr/lib/pkcs11
281474976935494: /lib/gawk /usr/lib/gawk
281474976938256: /lib/groff /usr/lib/groff
281474976939240: /lib/security /usr/lib/security
281474976939616: /lib/engines-1.1 /usr/lib/engines-1.1
281474976939876: /lib/sasl2_3 /usr/lib/sasl2_3
281474976940081: /lib/p7zip /usr/lib/p7zip
Not so good... too much hits:
"/lib/pkcs11 /usr/lib/pkcs11" are already in "/lib /usr/lib"
