You can use doskey to create an alias on any version of windows up to Windows XP (I'm not sure if it's available on Vista).
doskey will only work within the environment that it's invoked in and if you want the aliases to be available every time you start cmd.exe will need to write a script that will load them upon invoking your cmd prompt (cmd /K "My_Environment_Script.bat").
Example:
I often need to change drives and cd doesn't handle it very well but chdir does. However, the length of the command is tiresome to type every time I need it so I do this...
So when I type:
This question maybe in the wrong category but I'm posting here due to urgency.
In DOS is there a command to perform a similar function to spool command in SQL or Script command in UNIX?
I want to print all command line output to a file but I don't want to use the echo command for each line.

I have navigated every DOS and UNIX FAQ to find the DOS equivalent of the UNIX ps command (ps -f would be even better) but all listings of DOS<>UNIX commands do not have it (they all have the same basic commands listed). DOS must have a way of detecting running processes and TSRs. mem /c is the... (7 Replies)

Dear All
Could you please advice how do we convert a unix file to dos
I know one command,ux2dos, which somehow does not work to give desired output
Inputs on this is appreciated

In Unix I can use command line to do a find for files older than so many days and remove them. I can also capture the date to see if its a saturday and do something different. Are there any dos/intel command line equivalent commands to do this on a windows 2003 server? This is from an... (6 Replies)
i know after you do something in smitty via the gui, you can click something in smitty that will show you how to do the same thing via the command line, (not using the gui) can anyone tell me how (2 Replies)
Hi,
The title of this post is a little vague but I couldn't think of what to call it.
In Unix you can perform the following command
ftp -v IPADDRESS <<END
put FILE
END
In a DOS command prompt, is it possible to do the same kind of thing that the "<<END" does?
So for example, ... (4 Replies)
Well,
this command has served me quite well under DOS

however in linux it just outputs:
"./install.sh line 1: '%%x': not a valid identifier.
Ideas ?

unknown
unknown(n) Tcl Built-In Commands unknown(n)
__________________________________________________________________________________________________________________________________________________NAME
unknown - Handle attempts to use non-existent commands
SYNOPSIS
unknown cmdName ?arg arg ...?
_________________________________________________________________DESCRIPTION
This command is invoked by the Tcl interpreter whenever a script tries to invoke a command that doesn't exist. The implementation of
unknown isn't part of the Tcl core; instead, it is a library procedure defined by default when Tcl starts up. You can override the
default unknown to change its functionality.
If the Tcl interpreter encounters a command name for which there is not a defined command, then Tcl checks for the existence of a command
named unknown. If there is no such command, then the interpreter returns an error. If the unknown command exists, then it is invoked with
arguments consisting of the fully-substituted name and arguments for the original non-existent command. The unknown command typically does
things like searching through library directories for a command procedure with the name cmdName, or expanding abbreviated command names to
full-length, or automatically executing unknown commands as sub-processes. In some cases (such as expanding abbreviations) unknown will
change the original command slightly and then (re-)execute it. The result of the unknown command is used as the result for the original
non-existent command.
The default implementation of unknown behaves as follows. It first calls the auto_load library procedure to load the command. If this
succeeds, then it executes the original command with its original arguments. If the auto-load fails then unknown calls auto_execok to see
if there is an executable file by the name cmd. If so, it invokes the Tcl exec command with cmd and all the args as arguments. If cmd
can't be auto-executed, unknown checks to see if the command was invoked at top-level and outside of any script. If so, then unknown takes
two additional steps. First, it sees if cmd has one of the following three forms: !!, !event, or ^old^new?^?. If so, then unknown carries
out history substitution in the same way that csh would for these constructs. Finally, unknown checks to see if cmd is a unique abbrevia-
tion for an existing Tcl command. If so, it expands the command name and executes the command with the original arguments. If none of the
above efforts has been able to execute the command, unknown generates an error return. If the global variable auto_noload is defined, then
the auto-load step is skipped. If the global variable auto_noexec is defined then the auto-exec step is skipped. Under normal circum-
stances the return value from unknown is the return value from the command that was eventually executed.
