Shell command to generate `variables.tf` file in terraform
Here is small script that can help generating the variables.tf
file by reading other .tf
files.
Warning, below command overwrites your current variables.tf
file.
grep -oE "var\.(\w+)" main.tf | awk '!a[$0]++' | while IFS= read -r line; do echo $line | cut -d '.' -f 2 | awk '{print "variable \""$1"\" {\n description = \"\"\n}\n"}' ; done > variables.tf
