QSHELL on iSeries April 14, 2006

Ever wondered about QSHELL? It is a UNIX shell on iSeries. To access QSHELL, type in STRQSH on the command line. But before you go any further, head out to Thibault Dambrine’s tutorial : Exploring iSeries QSHELL: Concepts & Tutorial.

This tutorial explains in simple language the syntax of Unix commands, where to find help, how permissions work, and the basics of how to write a QShell script.

Some background on QSHELL: To be fully Java compliant, IBM needed to supply a JDK (Java Development Kit) on its iSeries eServer that could run standard Java commands such as Java, Javac or Javadoc, the same way other (UNIX) systems could. There was only one snag, OS/400 was NOT  ’a flavor of’ UNIX. The OS/400 IBM team resolved this hurdle by supplying a new ‘UNIX style shell‘ on the iSeries and appropriately named it ‘QSHELL‘.
