multiple string replacement with sed

I'm using sed to replace string in a text file containing the following:

prop="distributed-${DEPLOY_ENV}.properties, database-${DEPLOY_ENV}.properties, compute-${DEPLOY_ENV}.properties"

using the following command in a script:

#!/usr/bin/env bash
env=dev
sed \
-e "s/\${DEPLOY_ENV}/"${env}"/" \

But I get the following output; only the first occurrence of DEPLOY_ENV is replaced:

prop="distributed-dev.properties, database-${DEPLOY_ENV}.properties, compute-${DEPLOY_ENV}.properties"

How to replace all the occurrences instead of the first?

The correct syntax is:

$ env=dev
$ sed 's/${DEPLOY_ENV}/'"$env"'/g' file
prop="distributed-dev.properties, database-dev.properties, compute-dev.properties"

sed "s/\${DEPLOY_ENV}/"${env}"/g"

Add /g for global.

You just need to make the scope global by adding "g" so that you affect all occurrences of the match.

#!/usr/bin/env bash
set -x
env=dev
sed \
-e "s/\${DEPLOY_ENV}/"${env}"/g" \

and run the command as follows (where text_file_with_envs.txt represents your original file and text_file_with_envs.txt.new is your update file ):

$ ./sed-multi-repl.sh < ./text_file_with_envs.txt > ./text_file_with_envs.txt.new

this is the output of the cat on new file:

$ cat  text_file_with_envs.txt.new

prop="distributed-dev.properties, database-dev.properties, compute-dev.properties"
