Linux Shell Scripting Cookbook - Third Edition

Searching based on file size

Based on the file sizes of the files, a search can be performed:

# Files having size greater than 2 kilobytes
$ find . -type f -size +2k

# Files having size less than 2 kilobytes
$ find . -type f -size -2k

# Files having size 2 kilobytes
$ find . -type f -size 2k

Instead of k, we can use these different size units:

• b: 512 byte blocks
• c: Bytes
• w: Two-byte words
• k: Kilobytes (1,024 bytes)
• M: Megabytes (1,024 kilobytes)
• G: Gigabytes (1,024 megabytes)
