How can I capture the error returned from mysqldump and use it to take another action in a shell script? -


i'm using mysqldump in shell script dump several schemas production environment local one.

schemas = (one 2 three) read -p "enter username: " un    read -s -p "enter password: " pw schema in "${schemas[@]}"   :   mysqldump -h serv -u $un --password=$p > /dev/null 2>&1 | mysql -uroot local done

i'm redirecting out , error /dev/null prevent warnings , error messages, want able catch error , else based on output (e.g. access denied, not found).

how can capture error returned mysqldump , use take action in shell script?

for it's worth, $? variable seems 0 after mysqldump completes, if stderr access denied.

i did little more research , found answer here:
