Hi there.
Use the du or df command ( du /etc or df /etc).
Last line will be summary line in OS-blocks.
Multiply this with the blocksize and you have the result in bytes or kB.

Hi,

#df -k gives disk details of all the existing filesystems.
If you want particular directory or directory
for e.g for /var
#df -k /var
for subdirectory /var/yp
#df -k /var/yp

hmmmz, df (like bdf) works on filesystem level.
"df /tmp", "df /tmp/subdir1" and "df /tmp/subdir1/subdir2" will return the same output if the subdirectories are on the same mountpoint.

"du -s" on the other hand, compute the space used in the directory and subdirectories (if "-s" is specified) specified.

du -sk /dir_to_check, for the total occupied space by the dir.
or
du -k /dir_to_check, to display the space occupied by the subdirs and dir.

Thanks every experts!

Then how to check how much space remained, how much used in a particular sudirectory?like
/home/username/subdir1/subdir2?

You can use "du -sk *" command to check the disk space of the directory/subdirectory !

$du -sk /home/user/dir/subdir

you can use * to check all the subdirectory of one directory !

$du -sk /home/user/dir/*

The directory has no concept for free disk space , all dir share the disk space of the file system ,so you just only use "bdf" to get the free disk space of a file system .
