问题 I am trying to write a powershell script that tests if a MySQL login is successful by using $? to check if an error occurs. I also want to suppress all output - successful or not successful - from the command. These are the things I've tried: mysql -u root --password=mypass -e "show databases" If ( $? ) { echo "Hooray!" } Else { echo "Boo!" } This works correctly but doesn't suppress any output. mysql -u root --password=mypass -e "show databases" > $null Works correctly still but does not

For example, to capture web traffic. tcpdump -s0 -i any -wfile.pcap port 80 To watch it directly remove the -wfile.pcap To read a previously saved file tcpdump -r

问题 When I generate my entities I have a file prefixed with ~ like a backup file or something Is it a bug or you need to manually remove them? 回答1: From the official documentation in Symfony2 CLI command: $> php app/console help doctrine:generate:entities ....

Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . I have never used PHP with CLI, but I have seen scripts running with PHP code.
