All .Mount/\Commands are dynamically adjusted when loading so as to obtain CONSISTENT RESULTS regardless of the machine that the command is executing on.  All of those Fuming "Syntax Ditches" where commands behave differently on different platforms are bypassed.

So instead of remembering a multitude of "special cases" like

"I need a rope to get over ditch #1"
"I need a shovel to get across ditch #2"
"I need to stand on my left foot and blink my right eye at exactly 6:14PM local time to climb out of ditch #3"

Just use .Mount/\Commands and walk across the bridge!

Now you can get on with whatever you planned to do today instead of spending several fuming hours trying to juggle % signs!

Many commands also have an equivalent in the e[Command] Series.  This series contains "pre-escaped" versions of a .M/\C that can be used inside the ()'s of a FOR loop.

For example,

%.Quiet% SET var

will suppress normal output and only show errors

FOR /F "tokens=* delims=" %%A IN ('%.eQuiet% SET var') DO ECHO:%%A

will do the same thing.

Here's a quick list of .Mount/\Commands:

.Get[value] Series

1. Retrieve, optionally reformat and display a single value to the console
2. Place the retrieved value in a variable named #value
3. Set an errorlevel, if applicable, based on the result

(sample times and dates are based on Wednesday, January 1, 2003 at 7:05:30.07 AM local time)

If multiple instances of value are found, the .Get[Value] command will return "multi".  In that case, use the associated .List[Value] command to display all instances, one per line.  If no instances are found, .Get[Value] will return "none".

.List[value] Series

1. Retrieve, optionally reformat and display one or more instances of value to the console
2. Set an errorlevel, if applicable, based on the result
    

The .ListValue command will list all instances of value, one per line.  If no instances of value are found, nothing will be returned.

.[value]Echo Series

These commands change the behavior of the ECHO command, allowing you to prefix the text to be ECHOed with commonly needed values such as timestamps, etc.  All commands in this series will expand any variable in the optional "Text".

For example:

C:\>SET "var=My message"
C:\>%.ldtEcho% %var%
20030101 070530 My message

.if[Condition]/.ifNot[Condition] Series

These commands are actual IF statements which are dynamically generated when loading the .Mount/\Command Set.  They will evaluate to TRUE or FALSE based on the status of their "Condition".  Most .if commands have an equivalent .ifNot that evaluates exactly opposite.

.is[Pattern]/.isNot[Pattern] Series

Is[Pattern] IsNot[Pattern] Series

Command1 Is[Pattern]    Command2
Command1 IsNot[Pattern] Command2

In either case Command2 will only be executed if the output of Command1 matches (or DOES NOT MATCH) the [Pattern].  Available [Patterns] are:

Alpha - matches any upper or lower case letters (A-Z and a-z)
Num - matches numbers (0-9)
AlphaNum - matches letters and numbers (A-Z, a-z, and 0-9)

Examples:

ECHO:%1 %.IsNum% ECHO:The first parameter is numeric.
ECHO:%* %.IsNotAlphaNum% ECHO:Contains non-alphanumeric characters.

This series is also called "Bridge" commands.  Think of it this way.  You can only cross the "bridge" and execute Command2 if you match (or DO NOT MATCH) the [Pattern].

.Redir Rapids Series

These commands control what gets displayed to the console and/or a log file.  They give you complete control over every line of code.  Most of these can be used as a prefix or as a suffix.

COPY Source Destination %.Silent%

is equivalent to

%.Silent% COPY Source Destination

.SetEL[n]/.ifEL[n]/.ExitEL[n] Series

These commands can be used anywhere in a script to set the errorlevel using ONLY builtin commands.  Commands are dynamically adjusted, when necessary, to PERFORM CONSISTENTLY under NT/2K/XP/K3.

There are .SetEL, .ifEL and .ExitEL commands for errorlevels -1, 0, 1, 2, 3, 4, 123, 129, 161, 255 and 9009.
