For everybody interested in portable shell programming I like to recommend the following page which offers a good overview over POSIX compliant commands with links directly into the POSIX standard:


Is POSIX relevant today? I'd think that overwhelming majority of the shell scripts would require either Linux or BSD dialects.

And if one wanted to limit my shell scripts significantly, I'd limit myself to commands supported by busybox's "ash" shell -- this is a limited shell environment which is pretty widely used in initrd's and embedded devices.
