# Shell: Finding Files of a Given Size

Posted on November 2, 2013

A brief info of how to use the find command...

### Usage

In the current directory (.), finding files with size greater than 4096 bytes:

$find . -type f -size +4096c  In the current directory (.), finding files with size lower than 4096 bytes: $ find . -type f -size -4096c


As per the man page of find, the size can be specified as follows:

-size n[cwbkMG]
File uses n units of space. The following suffixes can be used:
b'    for 512-byte blocks (this is the default if no suffix is used)
c'    for bytes
w'    for two-byte words
k'    for Kilobytes       (units of 1024 bytes)
M'    for Megabytes    (units of 1048576 bytes)
G'    for Gigabytes (units of 1073741824 bytes)
The size does not count indirect blocks, but it does count
blocks in sparse files that are not actually allocated. Bear in
mind that the %k' and %b' format specifiers of -printf handle
sparse files differently. The b' suffix always denotes
512-byte blocks and never 1 Kilobyte blocks, which is different
to the behaviour of -ls.


In the current directory (.), deletion of files with size equal to zero:

\$ find . -size 0 -delete
