UNIX command to get inode's tid and pid
Hi everyone,

I am new here in www.unix.com, i found this site because I am looking for an answer to this problem of mine.

I need to know a UNIX command to display an inode's thread id and process id.

Hope someone can help me on this.

Thanks Smilie

Do you mean display the process that has a file (access file name by inode) open?
An inode all by itself is part of the file system and has no relation to a process except when something has the file open. You also have to know which filesystem you have the inode from. Inode numbers are not unique systemwide, they are only unique inside one filesystem

Assuming what I said, assume your inode is 42:
Code:
fname=$(find /path/to/filesystem -inum 42 -print \;)

You now have a filename. You can use lsof or fuser to see what process, if any, has the file open. The presence lsof and fuser depend on what flavor of unix you have.

Continuing on. Once you know the PID attached to the inode you can use HP Glance Plus (chargeable package) to find out the Thread Id (TID).

How will I use HP Glance Plus to get the TID and where will I get one? Can I use this on UNIX?

Thanks

What I am doing was getting the thread id of an inode in which the inode points to a connection to the server. The code I am using to get the inode for the connection was:

Code:
netstat -aeent | grep [ip address]

Kindly advise on what to do to get the thread id, I already searched on google but can't find anything. Thanks you for the help.

These command options are invalid on HP-UX . Am I mistaken in assuming that you have HP-UX?


Please define what you think an "inode" is ?


If you are not running HP-UX , what Operating System do you have?

I said UNIX in my first posts but its actually Linux 2.4.21, sorry for the confusion. I checked it using 'uname -a'.

That is quite an old version of the Linux kernel. What exactly do you plan to use the TID for once you identify it?
