<div><p>AIX<sup>®</sup> and <span class="keyword">i5/OS™</span> use different line terminating
|
||
|
|
characters in text files (for example, in files and shell scripts).</p>
|
||
|
|
<p>The AIX applications
|
||
|
|
that are the source for your <span class="keyword">i5/OS</span> PASE
|
||
|
|
programs expect that lines (for example, in files and shell scripts) will
|
||
|
|
end with a line feed (LF). However, PC software and typical <span class="keyword">i5/OS</span> software
|
||
|
|
often ends lines with a carriage return and line feed (CRLF).</p>
|
||
|
|
<pre>awk '{ gsub( /\r$/, "" ); print $0 }' < oldfile > newfile</pre>
|
||
|
|
<div class="section"><h4 class="sectiontitle">CRLF used with FTP</h4><p>One example of where this difference
|
||
|
|
can cause problems is when you use File Transfer Protocol (FTP) to transfer
|
||
|
|
source files and shell scripts from AIX to the iSeries™. The FTP standard calls for data
|
||
|
|
sent in text mode to use carriage return and line feed (CRLF) at the end of
|
||
|
|
a line. On AIX,
|
||
|
|
the FTP utility strips the carriage return (CR) when it processes an inbound
|
||
|
|
file in text mode. <span class="keyword">i5/OS</span> FTP
|
||
|
|
always writes exactly what is presented in the data stream and always retains
|
||
|
|
CRLF for text mode, which causes problems with the <span class="keyword">i5/OS</span> PASE
|
||
|
|
run time and utilities.</p>
|
||
|
|
<div class="p">Where possible, use binary
|
||
|
|
mode transfer from an AIX operating system to avoid this problem. Text files
|
||
|
|
transferred from personal computers will, in most cases, have CRLF delimiting
|
||
|
|
lines in the file. Transferring the files first to AIX will correct the problem. The following
|
||
|
|
command can be used as a means to remove the CR from files in the current
|
||
|
|
directory:<pre>awk '{ gsub( /\r$/, "" ); print $0 }' < oldfile > newfile</pre>
|
||
|
|
</div>

||
|
|
</div>
|

|
|
<div class="section"><h4 class="sectiontitle">CRLF used with iSeries and PC editors</h4><p>You
|
||
|
|
can also experience problems when you edit your files or shell scripts with
|
||
|
|
editors on your iSeries server
|
||
|
|
or with editors on your workstation (such as Windows<sup>®</sup> Notepad editor). These editors
|
||
|
|
use CRLF as a new line separator, and not the LF that <span class="keyword">i5/OS</span> PASE
|
||
|
|
expects.</p>
|
||
|
|
<p>Numerous editors are available (for instance, the <tt>ez</tt> editor)
|
||
|
|
that do not use CRLF as new line separators.</p>
