@svh1985:
1. Since you're running Sergey's stuff, I'm *vaguely* assuming you mean KFMon entries and/or PNGs, so, see
this post for NM entries populated by the KFMon generator, and as for actual PNGs "books", just know that you can remove them safely if you're using a current KFMon version.
2. Nope, it's only a placeholder on empty configs.
3. Everything you posted is commented out, so, nothing will actually do anything there.
TL;DR: We'll need your *full* config setup to grok what's happening (possibly KFMon's, too).
Sidebar: Never add an explicit /bin/sh or /bin/sh -c to a cmd_* entry, that's already done internally.
Sidebarē: I/O redirection makes no sense on a cmd_spawn, unless the actual script is very badly behaved.
