How to see variables inside ' ' ?

Carmen Carrero_vae3fo

Hello,

I'm using bitbucket pipelines and I need to use the value of a variable but inside of ''.

For example, I want the following: 'environment=dev' and dev is the environmentValue variable.

If I write 'environment=$environmentValue' the result is 'environment=$environmentValue' and not 'environmnet=dev'.

However, if I write echo $environmentValue the result is dev, so I think the error is '' but I need write it with the ''.

Thank you!!

Hi Carmen and welcome to the community!

Everything you put inside single quotes gets interpreted literally, so variables are not substituted. This is a feature of the shell and not specific to Pipelines, please see here for reference:

Variables are substituted inside double quotes. If you use

echo "'environment=$environmentValue'"

you are going to get

'environmnet=dev'

Is this something that works for you?

Kind regards,
Theodora
