read -r in ksh93 will leave the \n as they are. You can then use echo (or printf) to translate them to the correct character:
Hmm... this can be done. But it requires a step of post-processing the value after read, which I was trying to avoid.
Seems like extra processing will be required to solve my problem.
Hi All
At the moment the following code works but ideally i do not want to have to change the original $1
tr "\r" "\n" < "$1" > "$1.fix"
printf "\n" >> "$1.fix"
mv "$1.fix" "$1"
FILE=$1
coffee_out="splitmovie"
coffee_fill="-splitAt"
coffee_end="-self-contained -o output.mov $2"... (1 Reply)

Hi ,
I am working on Linux, with ksh93 installed.
The following statement
echo \\n
just prints
\n on this shell.
However on pdksh
echo \\n gives a blank new line as a output.
What is the correct way of printing a new line character on the ksh93? (4 Replies)
Hi,
My program uses gl_get_line from libtecla to get user input from terminal. It works fine as long as I enter English at the terminal prompt. However, if I enter other languages, such as Chinese characters, either by typing in or cut-and-paste, the input characters get cleared from terminal... (5 Replies)

Hello,
I have snippet code from Lippman's <<C++ primer>>.

builtin
builtin(1) User Commands builtin(1)NAME
builtin - ksh93 built-in function to add, delete, or display shell built-ins
SYNOPSIS
builtin [-ds] [-f lib] [pathname ...]
DESCRIPTION
The ksh93 builtin command adds, deletes, or displays built-in commands in the current shell environment. A built-in command executes in the
current shell process and can have side effects in the current shell. On most systems, the invocation time for built-in commands is one or
two orders of magnitude less than commands that create a separate process.
For each pathname specified, the basename of the pathname determines the name of the built-in. For each basename, the shell looks for a C
level function in the current shell whose name is determined by pre-pending b_ to the built-in name. If pathname contains a forward slash
(/), the built-in is bound to pathname. A built-in bound to a pathname is only executed if pathname is the first executable found during a
path search. Otherwise, built-ins are found prior to performing the path search.
If pathname is not specified, builtin displays the current list of built-ins, or just the special built-ins if the -s option is specified,
on standard output. The full pathname for built-ins that are bound to pathnames are displayed.
Libraries containing built-ins can be specified with the -f option. If the library contains a function named lib_init(), this function is
invoked with argument 0 when the library is loaded. The lib_init() function can load built-ins by invoking an appropriate C level function.
In this case there is no restriction on the C level function name.
The C level function is invoked with three arguments. The first two are the same as main() and the third one is a pointer.
The ksh93 builtin command cannot be invoked from a restricted shell.
OPTIONS
The following options are supported:
-d Delete each of the specified built-ins. Special built-ins cannot be deleted.
-f lib On systems with dynamic linking, load and search for built-ins in the shared library, lib.
Libraries are searched for in $PATH and system dependent library directories. The system dependent shared library prefix or suf-
fix can be omitted. Once a library is loaded, its symbols become available for the current and subsequent invocations of builtin.
Multiple libraries can be specified with separate invocations of builtin. Libraries are searched in the reverse order in which
they are specified.
-s Display only the special built-ins.
OPERANDS
The following operands are supported:
pathname Specifies the pathname. The basename of the pathname determines the name of the built-in.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
EXAMPLES
Example 1 Loading a builtin Command
The following example loads a builtin command mycmd from the library libfoo.so:
example% builtin -f foo mycmd
