Is the inode the inode of a directory you want the name of, or is it the inode of a file in some containing directory which you want to know the name of? – Null Set Jan 05 '11 at 15:48

2You do realize that a given file can be in several different directories, don't you? – David Thornley Jan 05 '11 at 18:03

Could you give an example of how you might use this feature (and how it is useful)? – nategoose Jan 05 '11 at 22:41

This is impossible without searching through the filesystem for a dir that contains a file with the given inode. Filenames are named references to inodes with no backlinks.

List the directory and get the inode of .. then list that and find the name of the file there that has the inode you are looking for.

How do you list the directory if you only know the inode? (That's significantly different than having a file descriptor.) – ephemient Jan 05 '11 at 16:27

@ephemient: Whoops. I guess that just seemed like such a useful thing that I assumed you could do it without being in the kernel. – Null Set Jan 05 '11 at 16:36

well its this, i am a chinese, and my linux system was configure to zh_CN.utf-8 lang, but as you know windows's default encoding is not this, and once i have use scp to copy files from windows to my linux server,then hold the original encoding, so it will display mass on my linux server, i think i can use ls -i to display all file or directory's inode value , then use cd -i inode_value to enter a directory that display mass – jyf1987 Jan 07 '11 at 05:51
