GNU Shell Utilities (shellutils), version 1.16 (xenix and UnixWare2, version 1.13) GNU Shell Utilities is a package of small shell programming utilities. They are mostly compliant with POSIX.2, where applicable. These utilities are generally more robust (have fewer arbitrary limits and more features) than the system supplied alternatives: basename printenv date printf dirname sleep env hostname expr tee false test groups true id tty nice uname nohup whoami pathchk yes echo who The logname utility is not delivered as it is not as robust as the one that comes with the system. The su and stty utilities are also not delivered.
