Command: del / erase
Del / erase deletes (erases) files.
Syntax:
1. DEL [{ options | pattern }]
ERASE [{ options | pattern }]
2. DEL [/P] [/V] [/?] [drive][path]filename
ERASE [/P] [/V] [/?] [drive][path]filename
drive Specifies the drive letter where the file is, e.g. C:
path Specifies the path to where the file is, e.g. \example\
filename Specifies the file(s) to delete. Specify multiple
files by using wildcards (*,?).
A period may be used to specify all files in the
current directory, and is the same as *.*
pattern If pattern matches a directory, all files within this
directory are deleted.
Options:
/P Prompts for confirmation before deleting each file.
/V Displays all deleted files.
/? Shows the help.
Comments:
If pattern matches a directory, all files within this directory are
deleted. When all files are to be deleted, a warning prompt is issued.
For performance reasons DEL / ERASE overwrites the first letter of
the filename by a '?'. It does not delete the file itself, but it
deallocates the space where the content of the file is written.
FreeDOS, as other DOSes, recognizes the renamed file (myfile.txt
becomes ?yfile.txt) as deleted, no longer shows it and does not
offer access to it. Programs like DEBUG which have sector access are
able to read the contents of the file. As long as you do not write on
the drive you have a chance to restore the file again with UNDELETE,
only the first character of the filename will be lost (_yfile.txt).
The only ways to delete the file CONTENTS FOR ABSOLUTELY CERTAIN are
to fill the disk completely with other files or by using a wipeout
tool. The only way to delete a file NAME FOR ABSOLUTELY CERTAIN is to
REN / RENAME the file first (e.g. "a.") and to delete it later (only
correct at 8.3 - not at long filenames!) You can also use ERASE
instead of DEL.
DEL is a command internal to command.com and needs no other file
in order to work.
Examples:
Example 1:
DEL FILE1.EXT FILE2.EXT
Deletes the files FILE1.EXT and FILE2.EXT.
Example 2:
DEL /P *.bak
Deletes all files with extension BAK, but prompts the user for each
single file before deleting it.
Example 3:
DEL.
Deletes all files within the current directory.
Example 4:
DEL /V *.txt
Lists the deleted files.
