hbsenvsubst
Substitutes the values of environment variables, but with handlebars.
About
Basically the idea of hbsenvsubst
is to work similar to envsubst
, but instead of using
shell format, it uses handlebars.
Please be aware that at this time, hbsenvsubst
should be considered a prototype that was quickly
rushed to play with this idea, so your mileage may vary.
Usage
hbsenvsubst < some-file-in > some-file-out
Example
An example handlebars input like this:
#!/bin/bash
echo "hello {{env.USER}}"
should yield hello foo
, given that the USER
environment variable is "foo".
Features

- environment variablesmem
