Question

If I want to replace for example the placeholder {{VALUE}} with another string which can contain any characters, what’s the best way to do it?

Using sed s/{{VALUE}}/$(value)/g might fail if $(value) contains a slash…

Answer 1

oldValue='{{VALUE}}'
newValue='new/value'
echo "${var//$oldValue/$newValue}"

but oldValue is not a regexp but works like a glob pattern, otherwise :

echo "$var" | sed 's/{{VALUE}}/'"${newValue//\//\/}"'/g'
