How to use \r and \n (new line character) with Curl command?

Question

I use following bash script line to update the description of GitLab group which use curl. But it prints in the description

Test_1\r\nTest_2\r\nTest3 

I want this

Test_1
Test_2
Test_3

Bash script command

curl --request PUT --header "PRIVATE-TOKEN: $GIT_TOKEN" "$GIT_API/groups/1079?description=Test_1\r\nTest_2\r\nTest3"

Answer 1

Use C-Style strings that can contain decoded escaped characters like:

$'Test_1\r\nTest_2\r\nTest3'

curl \
  --request PUT \
  --header "PRIVATE-TOKEN: $GIT_TOKEN" \
  "$GIT_API/groups/1079?description="$'Test_1\r\nTest_2\r\nTest3'

Eventually:

group_id=1079
group_description=$'Test_1\r\nTest_2\r\nTest3'

curl \
  --request PUT \
  --header "PRIVATE-TOKEN: $GIT_TOKEN" \
  "$GIT_API/groups/$group_id?description=$group_description"
