to STOP a command that is running in Command Line.

Front 13

ALIAS (short name) if

Back 13

In computing, aliasing describes a situation in which a data location in memory can be accessed through different symbolic names in the program. Thus, modifying the data through one name implicitly modifies the values associated with all aliased names, which may not be expected by the programmer. As a result, aliasing makes it particularly difficult to understand, analyze and optimize programs. Aliasing analyzers intend to make and compute useful information for understanding aliasing in programs.

Front 14

The DIR command

Back 14

The DIR command to see the contents of the current directory, and these important “switches” to modify DIR:

Front 15

DIR /A

Back 15

shows all files even hidden or system ones.

(the intended drive letter followed by the colon)

Front 23

What is the purpose of |MORE for some commands?

Back 23

the |MORE (pipe more) switch shows one screen of information, then pauses, instead of scrolling through. Many Windows 7 commands do not need this feature, as they automatically pause.

Front 24

Does “help” work with all commands in the CLI?

Back 24

HELP only works with certain commands. It does not work with many others, such as IPCONFIG. Use IPCONFIG /? instead.

Front 26

how to locate, for example, all files that END with ECPI

Back 26

DIR *ECPI.* (need .* so that any extension is found) , as opposed to all files that START with ECPI DIR ECPI*
as opposed to all files that CONTAIN ECPI anywhere in the name.... DIR *ECPI*
and how to find files that have ONLY FOUR characters after ECPI (total of 8 characters in their name, plus an extension) DIR ECPI????.*
