Using grep to remove from verbose call and saving in a shell script function

Question

I have a curl put request that I can use some unix command to see the stdout and stderr from.

If I add the line 2>&1 | grep -v "Authorization" At the end of my curl request, I can see the verbose output from my curl in my CLI minus a line that starts with "Authorization"

I tried creating a function with the above command, but when I call that function at the end of my curl request (like below) it no longer removes the "Authorization" line.

function remove_item_from_verbose { 
  2>&1 | grep -v "Authorization" 
}

echo -e "\n +++ Creating '$TENANT' tenant:\n"
# Create tenant
curl -L -X PUT "http://localhost:$HOST_PORT/admin/v2/tenants/$TENANT" \
    --verbose \
    --header 'Content-Type: application/json' \
    --header "Authorization: Bearer $AUTHORIZATION" \
    --data-raw "{\"allowedClusters\": [\"$CLUSTER\"]}" remove_item_from_verbose

AFAIK functions do work like that. What you are trying to so is add extra details to your command. You can do it like that:

#!/bin/bash

remove_item_from_verbose="2>&1 | grep -v \"Authorization\""

echo -e "\n +++ Creating '$TENANT' tenant:\n"

# Create tenant
eval curl -L -X PUT "http://localhost:$HOST_PORT/admin/v2/tenants/$TENANT" \
    --verbose \
    --header 'Content-Type: application/json' \
    --header "Authorization: Bearer $AUTHORIZATION" \
    --data-raw "{\"allowedClusters\": [\"$CLUSTER\"]}" "$remove_item_from_verbose"

Like this, $remove_item_from_verbose becomes a suffix of your command. Note the addition of eval in front of curl, it is required to have this suffix treated as part of the command.
