Q:
Bash script error: Variable not set when within a function?
In a bash script I've defined a function called myFunction that contains a variable $error. I'm calling this function from within the script with an echo statement, and I'm getting an error saying that $error is not set. Why is this?
Example:
#!/bin/bash
myFunction() {
echo "varA=$varA"
echo "varB=$varB"
echo "$error"
}
myFunction
$sh myscript.sh
myFunction: line 2: varA=filepath:/var/log/tomcat6/catalina.log: No such file or directory
myFunction: line 3: varB=deployed/tmp/app.log: No such file or directory
error: empty string
A:
You need to assign the variable in the function body:
#!/bin/bash
myFunction() {
varA=$varA
varB=$varB
echo "$error"
}
myFunction
