14 | # some of the tests: | |
15 | # | |
16 | # shell functions (do we care?) | |
17 | # var=${var:-val} | |
18 | # unset | |
19 | # set -- | |
20 | # IFS parsing | |
21 | ## not exiting with -e and failed "if", the way Ultrix does (Ultrix 4.2?) | |
22 | # "$@" expands to zero arguments if passed zero arguments | |
23 | # $SHELL -c 'echo $1' bad good | |
24 | # test -x | |

26 | # arithmetic expansion $(( ... )) | |
27 | # getopts | |
