[Pki-devel] Need help to store NSS DB response error message in variable using shell script

Hi Dev Team, I am writing a shell script for adding and deleting certificate in NSS DB at system level. I have a question that if I have to delete the CA certificate from NSS DB and suppose if its CRL file is also stored in DB, so I am thinking to delete the CRL file first and then CA certificate from NSS DB, for deleting the CRL we will use crlutil command and lets assume that if I have to delete CA certificate from NSS DB and its CRL file is not store there but delete command of CRL file has to execute before executing the delete command certificate. If CRL is not there then in command prompt it will show database error message that SEC_ERROR_CRL_NOT_FOUND: No matching CRL was found. So my question is that can I get this error message in variable to check and log it. I have executed code like this to store the response of crlutil delete command but it has directly printed on console. Below command I have used result=$(crlutil -D -d sql:/etc/pki/nssdb -n "Nickname"). If it possible to store response error message then please guide me so that I can use it in my code. Regards, Saurav
