A value without . in it is safest. The default value is \"/bin:/usr/bin:/usr/ucb\"." ac_help="$ac_help --enable-shell={sh,ksh} Specify the kind of shell that is to be built (the default is ksh). Specifiying sh compiles out: command line editing (emacs/vi), history, a bunch of aliases, [[ .. ]], select, let, brace-expansion, extended globing (*(..|..), etc.), co-processes, some special environment variables (ie, MAIL, MAILCHECK, MAILPATH, RANDOM, SECONDS, TMOUT)." ac_help="$ac_help --disable-emacs Compile out emacs command line editing (by default, this is compiled in for ksh, compiled out for sh)." ac_help="$ac_help --disable-vi Compile out vi command line editing (by default, this is compiled in for ksh, compiled out for sh)." ac_help="$ac_help --disable-jobs Compile out job control support. If your system doesn't support job control, this will automatically be compiled out." ac_help="$ac_help --disable-brace-expand Compile out brace expansion code (a{b,c} -> ab ac) (by default, this is compiled in for ksh, compiled out for sh). Brace expansion can also be disabled at run time (see set +o braceexpand)." ac_help="$ac_help --enable-history={no,simple,complex} By default, simple history is used for ksh, no history is used for sh. \`simple' means history file is read on start-up, written when shell exists. \`complex' means history files are updated after each command so concurrent shells read each other's commands. Note: \`complex' history doesn't work well across NFS; also, it requires the mmap() and flock() functions - if these aren't available, \`simple' history is automatically used." ac_help="$ac_help --enable-posixly-correct Enable if you want POSIX behavior by default (otherwise, posix behavior is only turned on if the environment variable POSIXLY_CORRECT is present or by using \"set -o posix\"; it can be turned off with \"set +o posix\"). See the POSIX Mode section in the man page for details on what this option affects. NOTE: posix mode is not compatable with some bourne sh/at&t ksh scripts." ac_help="$ac_help --enable-default-env=FILE Include FILE if ENV parameter is not set when the shell starts. This can be useful when used with rsh(1), which creates a non-login shell (ie, profile isn't read, so there is no opertunity to set ENV). Setting ENV to null disables the inclusion of DEFAULT_ENV. NOTE: This is a non-standard feature (ie, at&t ksh has no default environment)." ac_help="$ac_help --enable-silly [A silly option]" ac_help="$ac_help --enable-swtch For use with shell layers (shl(1)).
