sh Command
  
  
  Purpose
  
  Invokes the default shell.
  
  Syntax
  
  Refer to the syntax of the  bsh command.  The /usr/bin/sh file is
  linked to the Bourne shell.
  
  Description
  
  The sh command invokes the default shell and uses its syntax and
  flags.  The shell linked to the /usr/bin/sh path is the default
  shell.  The standard configuration  of the operating system links
  the /usr/bin/sh path to the Bourne shell.  See  "Using the Bourne
  Shell" in AIX Version 3.2 System User's Guide: Base and Devices
  for specific information about Bourne shell features.
  
  When invoked, single-byte versions of the login shell determine
  whether  the  environment is single- or multibyte (as defined  by
  the LANG environment variable in the /etc/environment file.) If
  the environment is  multibyte,  the  shell  invokes its multibyte
  version.  If the  environment is single-byte, the shell continues
  execution of its single-byte version.
  
  To run a multibyte version of the login shell in a single-byte
  environment,  you must invoke the shell by using  the  full  path
  name of its multibyte version.    This  version is located in the
  /etc/passwd file (see the  chuser command for information about
  changing  this  value.)  An  alternative  option is to change the
  value of the LANG environment variable in the single-byte version
  of the login shell and re-invoke the shell.
  
  Flags
  
  Refer to the flags for the Bourne shell ( bsh command).
