Question

I run

~ master $ ls -l@

I get

total 3

        com.apple.FinderInfo      32B

com.apple.FinderInfo seems to be some data-structure.

ls‘ option @ should display only

Display extended attribute keys and
sizes.

However, it displays a row with 32B which suggests me that it is a data-structure such as

0000   00 00 00 00 00 00 00 00 00 00 FF FF FF FF 00 00    ................
0010   00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00    ................

I would like to know why the ls -l@ shows the data structure.

Why does the ls -l@ shows the data structure at my Home?

Answer 1

It is an extended attribute. “com.apple.FinderInfo” is the key, and that binary data is the value.
