通过以JAVA开头的C ++应用程序运行Shell脚本

Question

My requirement is to start a c++ application which runs some shell scripts in a certain folder. the c++ app is started with java. The scripts its trying to run have being given chmod 777 access as well as the jar is started with sudo and the util is started with sudo from within the jar.

My problem is the scripts fail to run soemtimes saying script failed to run returned: 512 (the script is just an echo) I am running all command line function in java using getRuntime.exec (I tried process builder too) TLDR: jar starts c++ app c++ app tries to run shell script script fails sometimes Anyone got any suggestions or faces similar situation ?

EDIT 1 I should also mention that the scripts are being downloaded first via java. and then only passed on to the c++ app. The c++ utility works fine with scripts which are already there.I am using apache http client

Answer 1

我设法解决了这个问题，当c ++应用程序试图访问脚本时，仍然有一个输出流。
