See the first column.

A dash ( "-") indicates a regular file.

A directory is indicated by "d" in the first colum.

Likewise, "l" indicates a soft (symbolic) link, "s" a socket, "b" a block special file, "c" a character special file and "p" indicates a FIFO named pipe.

ls -l | grep ^-

lists all regular files,

ls -l | grep ^d

lists all directories etc.

You can use file (man file) to tell if it is a file or directory, example -

file abc.pem 
abc.pem: ASCII text, with CRLF line terminators
file ec/
ec/: directory

Open in new window


Edited: looks like omarfarid mentioned already.
