====== Setting Environmental Variables ======

The default behavior of TapeTrack programs can be changed by setting [[variable:start|Environmental Variable]].

These [[variable:start|Environmental Variable]] can be set using the following methods.

===== Windows Command Line =====

<code text;>
set VARIABLE=VALUE
</code>

Where ''VARIABLE'' is the [[variable:start|Environmental Variable]] name, and ''VALUE'' is the [[variable:start|Environmental Variable]] value.

===== Windows PowerShell =====

To set an [[variable:start|Environmental Variable]] in ''Windows PowerShell'', use the ''$env:'' command.

<code>
$env:TMSSREPORTFORMAT = "CSV"
</code>

Where ''TMSSREPORTFORMAT'' is the [[variable:start|Environmental Variable]] name, and ''CSV'' is the [[variable:start|Environmental Variable]] value.
<note important>
Using a Windows PowerShell variable $TMSSREPORTFORMAT = "CSV" will not be interpreted as a Windows variable and, as such,  will not be applied to the executable or output.</note>


===== Linux Shell =====

To set an [[variable:start|Environmental Variable]] in the Linux operating system, use the ''export'' command.

<code plain;>
export VARIABLE=VALUE
</code>

Where VARIABLE is the [[variable:start|Environmental Variable]] name, and VALUE is the [[variable:start|Environmental Variable]] value.

You can also prepend the [[variable:start|Environmental Variable]] to the command.

<code plain;>
TMSSREPORTFORMAT=CSV TMSS10Inventory
</code>
===== TapeTrack Config File =====

The TapeTrack Config File that is loaded when each [[:start#tapetrack-desktop-software|Desktop]] and [[cli:introduction|Command Line Program]] is initiated, it can also be used to set [[variable:start|Environmental Variable]].

<code plain;>
   variables = {
       TMSSLEVELNAMES = "A,B,C";
       TMSSNOLEVELSLOT = "1";
   };
