How to get command output in NSIS?

Question

I'm wondering, how do I get the output of an execwait command in NSIS. For example, if I run tree, how would I get the output, which would be the actual tree?

NSIS has instructions to enumerate files, see FindFirst in the helpfile – Romelda

The command I'm running isn't tree, it's a lot more complex. Tree is just an example. – Zarzuela

You can't do that with ExecWait, you have to use one of the plugins: nsExec, ExecDos or ExecCmd

Thanks. I ended up using: nsExec::ExecToStack 'command', pop $1 (for the exit code), pop $1 (for the ouput) – Zarzuela

ExecCmd now states: "This plug-in is no longer updated and has been superseded by the ExecDos plug-in." – Nun

@Romelda im using execwait to launch an exe but it is stuck on this command and it never proceeds. ExecWait "$INSTDIR\Application\abc.exe" – Aphonic

@Aphonic How is this related? ExecWait waits until the process ends. Is it stuck waiting for stdin? – Romelda

I want to run a command get its output and show it in textbox I'm using the following code and always getting 0 as the output nsExec::ExecToStack 'powershell -NoProfile -Command "$(& {$Args[0]})" "where code"' Pop $Output ; ${NSD_SetText} $LocationTextbox "$Output" – If
