Code:
 -c command-string the shell executes the command(s) contained in command-string

If I put a space character after 'ls', its working, does space tell shell that its not a script, but its a command !?
Code:
 
/home/userA>ksh 'ls'    
ksh: ls: cannot execute
/home/userA>ksh 'ls '
folderA folderB fileA fileB ...

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
