i5/OS PASE commands

Most i5/OS PASE commands support the same options and provide the same behavior as AIX commands, except in these areas:

• Many i5/OS PASE commands for display operations and UNIX^R job control only work in a TTY session such as a session started by the aixterm or xterm command. These functions do not work on 5250 workstation devices (including the display presented by program QP2TERM).
  
  
• i5/OS PASE generally does not support interfaces provided on AIX for system management. For example, i5/OS PASE provides no support for the AIX System Managment Interface Tool (SMIT) and does not support functions that require a SMIT database.
  
  
• i5/OS is fundamentally an EBCDIC system. i5/OS PASE shells and utilities run in ASCII and generally do no automatic conversion of stream data. You may need to use tools such as the iconv utility to convert between ASCII and EBCDIC encoding.
  
  Unlike the QShell interpreter and utilities, most i5/OS PASE shells and utilties do no automatic Coded Character Set Identifier (CCSID) conversion of stream file data. The i5/OS PASE utilities system, and any i5/OS PASE utility that runs a QShell command are exceptions because they provide CCSID conversion support for data the CL command or QShell command reads from standard input or writes to standard output or standard error.
  
  i5/OS PASE utilities that run QShell Java^(TM) utilities (such as the java command) set the Java file.encoding property to match the i5/OS PASE CCSID, so that stream data read and written by the Java program is converted from and to the i5/OS PASE CCSID. You can force a specific file.encoding value by setting i5/OS PASE environment variable PASE_JAVA_ENCODING before running the utility.
  
  
• i5/OS uses case-insensitive names for many system resources that have case-sensitive names in AIX (user and group names, object names in the root file system, and so on.). Some i5/OS PASE shell and utility functions require matching case for resources that have case-insensitive names in i5/OS, and others may return names in uppercase that would normally be lowercase on AIX. For example, file name expansion in i5/OS PASE shells is case-sensitive, so you must specify uppercase to match generic names in the /QSYS.LIB file system:

              ls /qsys.lib/qgpl.lib/GEN*.PGM
  rather than
              ls /qsys.lib/qgpl.lib/gen*.pgm
  

• To provide case-sensitivity and avoid name collisions with directories and files used for ILE support, most i5/OS PASE directories and files (including shells and utilities) are stored in the /QOpenSys file system. In particular, i5/OS PASE shells and utilities are in /QOpenSys/usr/bin and /QOpenSys/usr/sbin (rather than /usr/bin and /usr/sbin on AIX).

In addition to the i5/OS PASE commands listed below, each i5/OS PASE shell supports a number of built-in commands (such as cd, exec, if, etc.). See AIX documentation for information about the built-in commands supported by each i5/OS PASE shell and for detailed information about most of these i5/OS PASE commands:
