FILE contains the file names as they are read from stdin (Standard input).

KIND contains the text string that defines the type of file.

---

Display all text files in the directory /etc.

more `kind /etc/*`

That is actually hatched a list of all data files.

---

And if I have done the following sequence of commands cd /etc and kind -d *.

kind -d /etc/*

Possible result:

/etc/mnttab
/etc/utmp
/etc/wtmp

---

od `kind -d /etc/*`

---

ll `sh -x kind -a /lib/*` | m

---

find / -print | kind -x | while read FILE
     > do
     >        ll $FILE
     > done > /tmp/filelist
