da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin1. New features in 12/28/93b
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin a. If IFS contains two consecutive identical characters belonging
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin to the [:space:] class, then this character is treated as
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin a non-space delimiter so that each instance will delimit
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin a field. For example, IFS=$'\t\t' will cause two consecutive
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin tabs to delimit a null field.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin b. The getopts command has a -a name option that specifies a
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin name that will be used for usage messages.

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin b. When a shared library is loaded, if the function lib_init()
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin is defined in the library, it is invoked the first time that
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin the library is loaded with builtin -f library.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin characters in file names from both emacs and vi edit modes.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin a. The pipefail option has been added. With pipefail
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin enabled, a pipeline will not complete until all
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin commands are complete, and the return value will
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin be that of the last command to fail, or zero if
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin all complete successfully.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin b. When an executable is found on a given path,
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin the appropriate library path variable is prepended

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin5. New features in 12/28/93h
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin a. The PATH search algorithm has been modified to look
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin for a file named .fpath in each bin directory and if
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin found, to search for functions in this directory if
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin it cannot find the command in that directory.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin b. When performing pathname expansion, the shell checks
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin to see whether each directory it reads is case sensitive
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin or not, and performs the matching accordingly.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin c. The %T format for printing formatted date/time.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin6. New features in 12/28/93i

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin self documenting. Running command --man will produce
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin screen output. Running command --html produces the
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin man page in html format.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin b. The getopts builtin can process command description
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin strings to produce man pages.

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin a $((...)) expansion that contains a nested $var expansion
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin to be lost has been fixed.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin b. A bug that caused a core dump when a script that did not

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin now reports that foo isn't found rather than invoking foo.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin g. The previous version incorrectly listed -A as an
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin invocation option. The -A option is only for set.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin h. A bug was fixed which caused ksh to loop when execution trace

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin i. A bug which could cause the job control switch character
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin to be disabled when a script that enabled monitor mode

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin additional pointer argument that is passed to each invoked
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin function.

da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin is an argument list for the invoked discipline function
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin or built-in.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin k. A callback function can be installed which will give
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chin notification of file duplications and file closes.
