Hi,
I would like to set a value to a variable which is within a string.
example will give you better understanding
one file contains a string lets call him 'stringFile'
${install_path}/some/path/file.txt
now a bash script is reading this file and contains a variable install_path like this
#!/bin/bash
install_path="/usr/local"
while read line
do
echo "$line"
done < stringFile
Output of this script is: ${install_path}/some/path/file.txt
but i would like that the outpus is: /usr/local/some/path/file.txt
how to achieve this?
Thank you.
