Iselect is a curses based interactive selection tool. It can be used either as a user interface frontend controlled by a Bourne-Shell/Perl/Tcl backend as its wrapper or in batch mode as a pipeline filter (usually between grep and the final executing command).
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
