BackTick (2.x/3.x ONLY) (CLI Function)
NAME
BackTick- Allows you to include the text output of
one command to be the input of another command.
SYNOPSIS
SomeCLICommand `AnotherCommand`
DESCRIPTION
This is a new and important feature of 2.x/3.x.
BackTick lets you insert the text output of one command
to be the input of another command. For instance, if you
wanted to print the contents of the Work:ESCOM directory
with an informative header you would type this:
ECHO >prt: "The directories in work are:" `Dir
Work:ESCOM`
It's a good idea to know where this key is, so I'll
tell you. It is the key right above the Tab key. The
unshifted version of that key is the BackTick (`), the
shifted version is the Tilde (~). If you try to use the
parenthesis key (') your command will fail. There is a
difference between those two keys even though they look
similar on the screen.
The backtick command always evaluates itself at the
time it is issued. If you wish to have the backtick
command evaluated after several other commands have been
issued you must place the asterix (*) escape character
before each backtick.
For instance, lets say you want to create an alias
which displays the contents of the Gould:Loser directory.
You would type:
Alias grovel Echo "Contents of the Loser directory is: *`dir Gould:Loser*`
Now, whenever you want to see what is in that
directory you merely type 'grovel' and it will be shown.
But, if you don't include the asterixes then any changes
made to the Gould:Loser directory will not be reflected.
You will only see what was in that directory when the
Alias was first made.
With some experimentation you will find this DOS
function to be one of the most useful.
