『楼主』: [ 转帖] ListDirected Input for all Programs

@.COM : ListDirected Input for all Programs
                     (c) Ed Schwartz, Jul 95
            ===========================================

@.COM is a program that enables DOS to read program parameters not from
the comand line (as usual) but from an input file.

Syntax:       @ prog < listfile

where: "prog"    is *any* program or DOS command
                  (but *not* the SET command)

      "listfile" is an ASCII text file that contains the parameters
                  for program "prog"

@.COM will read the first line of "listfile" and then execute "prog"
with this line as parameters. Then @.COM will continue with the 2nd
line of "listfile" and so on, until all lines of "listfile" have
been executed.

Example:       assume you have a file DUMMY with the following contents:
               *.bat
               *.bak
               *.old
            and you call  @ DEL < DUMMY
            then the following commands will be executed:
               del *.bat
               del *.bak
               del *.old

Please be sure that the last line of "listfile" is terminated with a CR/LF.

Local and global parameters:
The parameters of "prog" may be specified either on the command line or in
the listfile. You may call  "@ DIR /W < listfile" . In this case the "/W"
has the same effect as if it were specified in every line of "listfile"

Keyboard input:
If you call @.COM without the "< listfile" part, it expects input from the
keyboard rather than from a file. @.COM will repeatedly read one line from
the keyboard and execute "prog" with this line as parameters. This will
save the repeated typing of the command name. Terminate @.COM by entering
Ctrl-Z.

Creating "listfile":
"listfile" may be created with any ASCII editor, or it may be the output
file of a DOS command like DIR. Assume, you want to delete the files *.BAK
and *.OLD in all (sub)directories of drives C: and D:

      1. enter  @ DIR /S/B > KILL  from the command line
      2. type C:\*.BAK <RET>
               C:\*.OLD <RET>
               D:\*:BAK <RET>
               D:\*:OLD <RET>
               Ctrl-Z <Ret>
      3. enter  @ DEL < KILL

Piping:
@.COM supports piping. Thus, if you need a more sophisticated file
selection you might for example use BORLAND's GREP.COM:
      DIR /B | GREP [opt] "searchstring" | @ DEL

@.COM and batch files:
"prog" may be a batch file that gets it's parameters line by line from
"listfile". Within this batch these parameters may be used as usual
(%1, %2 etc)
If you call @.com from within a batch, you must call @@.COM (because @
as the first character on a batch line has a special meaning).

@.COM and the SET command:
Since @.COM launches a 2nd copy of COMMND.COM it will not work with
the SET command (like most shells, e.g. Norton Commander).

To get @.COM copy the following code to a file @.DEB. Then call
      DEBUG < @.DEB
This will create @.COM. @.DEB may be deleted again.
