In ksh93 there is a -o multiline option, does pmksh suppport this?
原因
The pmksh shell is based on pdksh, a ksh88 clone. Becuase of this it doesn't support many new features added in ksh93. The full list of options support can be seen by running "pmksh -?"
解决办法
The enhancement request #6347 has been opened to add the multiline option to pmksh.
