Infinite loop

[komljen]

When using a default value that will have a : somewhere in the text, envsubst will go to infinite loop. For example:

$ echo '${SOME_URL-http://localhost:8080}' | envsubst

If I remove the quotes or add a double quotes it will work fine:

$ echo ${SOME_URL-http://localhost:8080} | envsubst
or
$ echo "${SOME_URL-http://localhost:8080}" | envsubst

However, if I want to replace the same env variable in the file it will be stuck:

$ cat file.txt
property=${SOME_URL-http://localhost:8080}

$ envsubst <file.txt >file2.txt
