EFTH MINIX report #37  - August 1988 -  stat(1)


There follows an implementation of stat(1) for Minix.
This command is useful for looking at the file size
of a special file.


----------------------------------------------------------
echo x - stat.1
gres '^X' '' > stat.1 << '/'
XCOMMANDS
X    stat(1)		- display inode contents
X
XINVOCATION
X    stat    [ file ]
X
XEXPLANATION
X    Stat(1) prints the contents of the inode for <file>.
X    If <file> is not specified then standard input is
X    investigated.
X
X    This command is used to obtain information that ls(1)
X    does not display: (a) The "size" of a special file
X    and (b) The major/minor unit number of the device
X    holding the <file>.
X
XREFERENCES
X    ls(1), stat(2)
