List only files in a directory and show the inode number

Question

How can I list all files but not directories in a given directory and show the inode-numbers.

Something like ls -li | grep ^- does not work since the inode number is shown in the beginning of the line.

Answer 1

There are multiple solutions. Assuming you do not have a filename starting with -

ls -li | grep " -"
ls -li | awk '/ -/'

If a directory contains -, it can be fixed by

ls -li | grep "[0-9][0-9]* -"
ls -li | awk '$2 ~ "-.{9}"'

Answer 2

You could use find:

find . -maxdepth 1 -type f -exec ls -li '{}' \;

or, to get ls-like output:

find . -maxdepth 1 -type f  -printf '%i %M %n %u %g %kK %Tc %p\n'

Parsing ls is a bad idea since it can often lead to trouble.

If you really want to use ls directly, you could do this:

ls -li | gawk '$2!~/d/'

Answer 3

Another find alternative:

find -maxdepth 1 -type f -printf "%i %p\n"

Or yet another:

find -maxdepth 1 -type f -ls

Answer 4

Here's an alternative way using the commands tree and grep. Grep is used to filter out the directory entries:

$ tree --inodes -f -F|grep -v "/$"

Example

$ tree --inodes -f -F|grep -v "/$"|less

The above incorporates the directory hierarchy into the lines for each file, and also makes use of the -F switch so that tree appends a trailing / to each line that's a directory. Utilizing that feature, we're able to grab any lines that now have this trailing / and omit them.
