Hey there.
I'm trying to pipe a password file into rsync. It works fine on the dos command line (rsync<passwordfile), but I have yet to get it to work via NSIS. I tried nsexec and execdos. The latter seemed promising but ultimately didn't work. I fed it the path to the password file in the second parameter, but rsync still waits for input.
Any help would be appreciated.

If you are using nsExec then you have to execute 'cmd.exe /c "c:\path\yourapp.exe" < "c:\path\somefile.ext"' etc
I tried that before but ended up with a message from CMD: "Input line is too long". Unfortunately there is not much I can do about the length of paths on a foreign system.
| < and > are handled by cmd.exe, maybe try a batchfile and/or 8.3 short paths?
IIRC one of the exec plugins on the wiki has custom stdin handling which might be worth a shot...

I noticed that I get the "Input line is too long" error whenever I add double quotes around the path to the file that is piped into rsync.
I found that this is an old windows bug, the solution is here: http://stackoverflow.com/questions/6...answer-3583282
The syntax that actually works is therefore:
nsExec::ExecToLog 'cmd.exe /c ""C:/path/to/program.exe" parameters < "C:/path/to/input-file.txt""'
In other words, the command that is handed to cmd.exe should be wrapped in another pair of double quotes.

MakeNSIS uses a different trick in its !system implementation:
cmd /c if 1==1 yourcommand
Interesting, that works as well. So it's the same bug.
On further inspection it seems to be enough to place only the first double quote before the command:
nsExec::ExecToLog 'cmd.exe /c ""program" parameters < "input-file"'
I wouldn't be surprised if there are more solutions to this. The extra quote is certainly the shortest, but I do like the if 1==1 solution, because it's an obvious workaround. Whereas juggling quotes could easily be interpreted as a typo by another person working on the code.

What if you change the order: < "file" "program" parameters
