Very strange: Process A started process B, B will fail to execute unzip command if A exited.

[yluo]

Process A start process B:
@
QStringList arguments;
...
QProcess::startDetached("ProcessB", arguments );
@
B execute unzip command:
@
QStringList arguments;
arguments<<source_zip_file;
arguments<<"-d";
arguments<<destination_path;
QProcess::execute("unzip", arguments );
@
But if I execute rm command, it will success.
@
QStringList args;
args<<"-drf";
args<<destination_path;
QProcess::execute("rm", args);
@
Any suggestion? Thanks!

welcome to devnet

Did you also try to launch ProcessB with execute for unzip?

Hi, koahnig, thank you
If launch ProcessB with execute, process A will not exited until process B exited, and process B will unzip successfully.
My problem is if process A exited before process B, process B will fail to unzip.

Processes form a tree, axing away one does hurt its children. There is little you can do about that.
