How to get info of specific iNodes inside Terminal
To get extended info of an existing inode use find:

sudo find / -inum $inode -exec ls -ilaO@ {} ";"


Replace $inode by the real inode-ID e.g.:

sudo find / -inum 1745768 -exec ls -ilaO@ {} ";"
find: /dev/fd/3: Not a directory
find: /dev/fd/4: Not a directory
1745768 -rw-r--r--  1 user  staff  - 79 13 Nov 12:30 /Users/user/.oracle_jre_usage/613bcfb3a06ef613.timestamp


To see the data use the appropriate app or a command line tool (cat, file etc).
