How do i find the no. of files in a filesystem?

Thanks

Hi David:

How about:

# cd
# find . -type f -print|wc -l

Hi David,

You can use df -i and take a note of used i-nodes.

df -i /file_system |grep used i-nodes

Hardway is

find /file_system |wc -l

or ..

# ls -lR|grep \^-|wc -l

Try "df -g" that gives the entire info about the filesystem you want and it gets this from the statvfs. It is much faster than anyother commands. As a Inode is allocated to each File the "total number allocated free inodes" lets you know how many files are there in the file system.
Goodluck

Hi,

#cd /
#find . -xdev -type f|wc -l

the -xdev keeps the search within the wanted FS and avoid scan in any other possible mounted FS inside of .

If you need include directories as file counter, pls omit "-type f" option.

It seems to me that all the solutions so far have holes in them. JRF's will not take into account whether or not a file system has filesystem mounted below it. To solve that problem you could use:

# find /filesystem -type f -xdev | wc -l

The solutions using 'df' will tell you the number of inodes used, but you have to remember that a directory, which is really a different type of file, also uses an inode. So if you just want 'files' then the df output will be misleading.

Take the following example on one of my machines.

# find / -type f -print | wc -l
91269
This found ALL files on the system, including those in /var, /usr, /tmp, etc.

Now this:

# find / -type f -xdev -print | wc -l
740
Found just files in /, and not any of the mounted filesystems.

# df -i
...excerpt....
2436 used inodes

That number is pretty close to the number of files and directories in /.

# find / -xdev | wc -l
2475

So, I think your best bet, be it a bit slow maybe, is

# find /filesystem_name -xdev -print | wc -l

Hi:

You can also do df -t and look at used inodes.

HI (again) David:

Jose and Patrick are correct. One should add '-xdef' to the find criteria to avoid crossing mountpoints.
