ABOUT

slick provides an alternative to sh -n, which is problematic for a number of minor reasons:

• sh is hardly ever a bare bones POSIX sh interpreter on most UNIX systems, but usually soft linked to bash, ksh, ash, or even stranger things. So anyone genuinely interested in vetting their #!/bin/sh scripts for compliance risks getting false negative scans for scripts that actually contain bashisms, kshisms, and so on. By contrast, slick guarantees pure POSIX parsing, so that scripts are scanned consistently regardless of the particular environment configuration.
• sh is difficult to obtain in Windows. Cygwin-like environments are themselves difficult to setup. Should a unix, Linux, Windows, or other system desire syntax checking, slick is easy to obtain by gox ports, or through the wonderfully cross-platform Go toolchain.
