问题 I am trying to exploit a buffer overflow in a challenge, the buffer gets it's value from an environment variable. In GDB I know that you can set environment variables using the command: set environment username = test However I need to pass the username variable special characters, so I need to do something like: set environment username= $(echo -e '\xff\x4c......') But that command doesn't get executed and the username variable contains literally what I wrote down, does anybody know a trick

问题 I have quite massive project which was developed in intellij Idea. Now I have to be able to run it from command line, but there are too many libraries including maven dependencies are used. Is there a way to get command line that is used by intellij idea when it runs a project? 回答1: If you use maven you can do this: mvn install mvn exec:java -Dexec.mainClass="com.module.Main" -Dexec.classpathScope=runtime 来源： https://stackoverflow.com/questions/26400893/run-intellij-idea-project-from-command

问题 How do I get the full width result for the *nix command " ps "? I know we can specify something like --cols 1000 but is there anyway I can the columns and just print out everything? 回答1: Try ps -w -w aux . The -w option sets the output to wide, and doing it twice makes the width unlimited. The "aux" part makes it show more information, and is (afaik) pretty standard mode to use. This is of course platform-dependant, the above works with procps version 3.2.7 on Linux. 回答2: Specify the w option

I cannot find correct syntax to use i as repeat count. 回答1: You will have to escape inner double quotes and use double quotes in shell for variable expansion: perl -e "print \"\x41\x42\x43\x44\x0a\" x $i" ABCD
