- ERA
- A Replacement for the DEL Command
- 27 Aug 88
-
- Program by Dennis Vallianos
- Notes by Irv Hoff
-
-
- ERA.COM is an MS-DOS "delete file(s)" program. Unlike the normal DEL
- command, it shows the names of the files that will be deleted, then
- asks if you really want to erase them.
-
- If a 'c' (for confirm) is appended to the command line, ERA will display
- the files matching the command line individually, then ask if you really
- want to erase each file.
-
-
- HOW TO USE ERA
-
- First, copy ERA.COM to a directory that is in your current PATH statement.
- ERA does not accept drive specifications, and will only work in the
- current drive and directory. If it is in a directory named in your PATH
- statement, you can use it in any directory. Floppy disk users should
- copy ERA.COM to their normal DOS disk.
-
- You can use ERA by entering one of the following commands. Notice the
- wildcard filename. Use *.* to indicate all files in the current
- directory.
-
- 1. ERA *.TXT
-
- 2. ERA *.TXT C
-
- The first example is for normal use. It shows the names of
- all files with a .TXT extent, then asks if it's OK to erase
- those files.
-
- The second example shows the files one-at-a-time and asks
- if you want to erase each file.
-
- (See below for an actual example)
-
-
- This very short (636 bytes) program has the tremendous advantage of
- allowing the user to SEE what will be erased and then verifying
- the command before erasing the files. This is a terrific advantage over
- the usual DEL command.
-
-
- EXAMPLE of its usefulness:
- --------------------------
- Recently I erased the entire UTIL directory of some 123 files,
- when I "thought" I was in another subdirectory where I did
- want to erase the entire contents (all three files). I gave the
- command:
-
- DEL *.*
-
- THEN discovered I was in UTIL and those files were GONE.
- Fortunately, I had a back up that was reasonably current,
- but what a nuisance!
-
-
-
-
-
-
-
-
- INSTALLING ERA.COM
- -------------------
-
- Just copy ERA.COM into in your UTIL or DOS directory.
- Make sure the directory chosen is in your PATH
- statement. Now, instead of entering DEL to delete a
- file, just enter ERA instead. If you enter DEL, you
- can still use the original DOS command.
-
- DEMO of ERA
- -----------
-
- Let's take a look at a simulated session with ERA. For the purposes
- of this simulation, assume there is a directory, named \UU on drive C:.
- Read along, pretending that you are entering the commands shown.
- Remember, ERA.COM must be in a directory contained in your PATH statement.
-
- C:\UU>dir
-
- Volume in drive C has no label
- Directory of C:\UU
