Which command will print out the attributes of the file foobar?

`ls-attrfoobar` is malformed - the tokens are concatenated without spaces, and the `ls` command has no `-attr` option for reading inode-level filesystem attributes.

`lsattr foobar` (shown as 'Isattr' due to a font rendering artifact where lowercase 'l' resembles 'I') is the standard Linux command for displaying inode-level filesystem attribute flags set by `chattr`, such as immutable (+i), append-only (+a), and no-dump (+d). It reads these flags directly from the filesystem and prints them for the specified file.

`printattr` is not a standard Linux command and does not exist in common distributions for displaying filesystem-level inode attributes.

`fileattr` is not a standard Linux utility; the correct command for listing inode-level filesystem attributes assigned by `chattr` is `lsattr`.
