How do I find all the large files in the directory?

The Find command under Linux is used to look up files and know that it is omnipotent through man find. So you can find files by file size. To search for size from man find, you can see the following information:

-size N[CWBKMG]

File uses n units of space. The following suffixes can be used:

b for 512-byte blocks (the "the default if no suffix is used)

C for bytes

W for two-byte words

K for kilobytes (Units of 1024x768 bytes)

M for megabytes (units of 1048576 bytes)

G for gigabytes (units of 1073741824 bytes)

Note: The default unit is B, and it represents 512 bytes, so 2 means 1k,1m is 2048, if you do not want to convert, you can use other units, such as C, K, m, etc.
