Oracle Scripting – How to Pass Oracle Wallet Auth to SH Script

I am running an Oracle DB update script that requires password. I have Oracle wallet installed. How to pass Oracle wallet to sh script so that I don't have to enter password when running the script?

I have my sqlnet.ora

sqlnet.expire_time=60
sqlnet.inbound_connect_timeout=300
sqlnet.allowed_logon_version_server=10
sqlnet.allowed_logon_version_client=10

WALLET_LOCATION =
(SOURCE =
   (METHOD = FILE)
      (METHOD_DATA =
          (DIRECTORY = /oracle/app/oracle/product/base19/19/network/admin/wallet)
   )
)

SQLNET.WALLET_OVERRIDE = TRUE
SSL_CLIENT_AUTHENTICATION = TRUE

Credentials are correctly installed:
$ mkstore -wrl "/oracle/app/oracle/product/base19/19/network/admin/wallet" -listCredential
