Vorwort - SSS-Tools für Power System i Syntax System Services

due to the high job startup cost versus the lightweight Unix processes. Since we’re all about
performance, I’m not going to illustrate that method.
If I look back at the reader’s original request, he only asked for a way to get at old files, not
necessarily automatically delete them. To achieve that, I’m going to slightly modify the original
command:
CRTPF NoQtempLib/YourFile
RCDLEN(5000)
STRQSH CMD(’find /home/elvis -atime +180 -print >
/QSYS.LIB/NoQtempLib.LIB/YourFile.FILE/YourFile.MBR’)
I don’t have Qshell installed, now what?
Fear not, there are always alternatives on our trusty iSeries.
With V5R3 IBM has included RTVDIRINF and PRTDIRINF with should look very familiar
to folks used to RTVDSKINF and PRTDSKINF. This will provide all the detail you want.
If you’re up for a little bit of programming, any of the Unix apis like readdir(), opendir(),
stat() etc. are available in all HLL programming languages (RPG,C,COBOL etc.). With access to
these, you can easily create your own commands, especially considering the wealth of examples
the Unix aficionados have placed on the World Wide Web. Alternatively, there are unique iSeries
APIs that perform well in relation to other approaches: Qp0lProcessSubtree, Qp0lGetAttr,
Qp0lUnlink.
I was going to write a command but then realized that the well known iSeries expert, Scott
Klement, has already done so:
