In Jack Wallen’s tutorial for builders, he present how straightforward it’s to set non permanent atmosphere variables in Linux.

Do you know that you may set non permanent atmosphere variables on the Linux working system? With these variables, you possibly can extra simply work with scripts and even systemwide applications. And for builders, setting atmosphere variables can turn out to be useful.

For instance, you would possibly need to set a brief variable for the model of your distribution you utilize, so downloading the right software to put in is far simpler. Or, perhaps you need to set a URL as an atmosphere variable to work with a script. You would set the MY_SITE variable as, say, techrepublic.com, and use the variable in a bash script. Subsequent, you may want that variable to vary, so you might reset the non permanent variable to a special web site, which suggests you don’t must edit your script. And when you set the atmosphere variable, it can work with any script needing to name that variable.

So, how do you set an atmosphere variable in Linux? Let me present you.

First, log into your Linux desktop or server and open a terminal window. Let’s set MY_SITE to techrepublic.com. For that, the command can be

export MY_SITE='techrepublic.com'

You may confirm the variable was set correctly by issuing the command

echo $MY_SITE

and it is best to see techrepublic.com printed. When you have to change that variable, run the export command with a special possibility rather than techrepublic.com. And that’s all there may be to it.
