C.ll. $ERASE - File Erasure
The program $ERASE helps you erase files you do not need any longer.
As
all
other utilities,
is has a number of particular features and can be
extended
by various options.
If you are using the command interpreter,
both forms of the command are applicable:
ERA
or
E~ASE
Both
notations
of the command have the same effect.
When
you
enter
nothing else but the command name, $ERASE will explain you precisely how
it is to be called. If you specify a filename, for example:
ERASE PROGMl.COM
$ERASE will try to erase that file.
If the file could be found, this is
indicated as stated below::
A:PROGMl
.COM
2 KB)
erased.
1 File(s) erased, 2 Kbytes released, 346 Kbytes remaining.
You see that you are informed of how much space the file occupied before
it
has been erased,
and how much space was regained by erasure. If the
file was not found, the message reads
No files found.
Of
course,
you can erase several files at once by specifying an
ambi-
guous filename. This might look as follows:
ERASE *.COM
3 files found. Erase? (Y/N) Y
A:$DIR
.COM (
HI
KB)
erased.
A:$SET
.COM (
B KB) r/o not erased.
A:PROGRAMM.COM {
20 KB)
erased.
2 File{s) erased, 30 Kbytes released, 376 Kbytes remaining.
For
safety,
in
the case of several files found,
$ERASE
asks
before
erasing
a
particular
file whether you want it
like
that.
The
file
"$SET.COM"
could not be erased,
because it has been write protected by
means
of
=>
$SET.
However,
activating an option would have
it
made
possible to erase it, too. This leads us to the options of $ERASE.
