Creating a Variable

Exporting a variable

• Exporting means making the value of the variable available to a shell spawned (created) by the current shell.

• There are two ways to export

  • Method 1: export myvar="value string"
  • Method 2: myvar="value string" ; export myvar (; ⇒ export myvar can be on new line as well)

• Variables created in one shell are not passed automatically to subshell

• Export the variable

<aside> 💡 NOTE: Modifying value of var in subshell does not change the value of var in parent shell

Using variable values

• echo $myvar
