Question

I want to replace all occurrences of {{password}} or {{ password }} or {{password }} in files with some string using sed i am able to remove with know number of spaces , but could not remove all combinations.

i could replace using , but not all combinations

sed -i -e "s/{{ password }}/$password/g" test.sql

note that you'll have to make sure password variable doesn't contain \ or & or the delimiter character which / in the example used above.. see also: stackoverflow.com/questions/29613304/… — Sundeep

also, as a good practice, I'd use 's/{{ password }}/'"$password"'/g' to avoid double quotes conflicting with sed command — Sundeep

If the number of spaces is arbitrary, then you could search for zero or more spaces (*) instead of just one space () with something like {{ *password *}}.

if you are using regex, I often use "\s" instead of " " just to be sure there are not tabs or other whitespace characters "posing" as a regular space.
