copied!<p>I created a bash script that parses ASCII files into a comma delimited output. It's worked great. Now, a new file layout for these files is being gradually introduced.</p> <p>My script has now two parsing functions (one per layout) that I want to call depending on a specific marker that is present in the ASCII file header. The script is structured thusly:</p> <pre><code>#!/bin/bash function parseNewfile() {...parse stuff...return stuff...} function parseOldfile() {...parse stuff...return stuff...} #loop thru ASCII files array i=0 while [ $i -lt $len ]; do #check if file contains marker for new layout grep CSVHeaderBox output_$i.ASC #calls parsing function based on exit code if [ $? -eq 0 ] then CXD=`parseNewfile` else CXD=`parseOldfile` fi echo ${array[$i]}| awk -v cxd=`echo $CXD` .... let i++ done>>${outdir}/outfile.csv ... </code></pre> <p>The script does not err out. It always calls the original function "parseOldfile" and ignores the new one. Even when I specifically feed my script with several files with the new layout. </p> <p>What I am trying to do seem very trivial. What am I missing here?</p> <p>EDIT: Samples of old and new file layouts.</p> <p>1) OLD File Layout</p> <pre><code>F779250B =====BOX INFORMATION===== Model = R15-100 Man Date = 07/17/2002 BIST Version = 3.77 SW Version = 0x122D SW Name = v1b1645 HW Version = 1.1 Receiver ID = 00089787556 =====DISK INFORMATION===== .... </code></pre> <p>2) NEW File Layout</p> <pre><code>F779250B =====BOX INFORMATION===== Model = HR22-100 Man Date = 07/17/2008 BIST Version = 7.55 SW Version = 0x066D SW Name = v18m1fgu HW Version = 2.3 Receiver ID = 028910170936 CSVHeaderBox:Platform,ManufactureDate,BISTVersion,SWVersion,SWName,HWRevision,RID CSVValuesBox:HR22-100,20080717,7.55,0x66D,v18m1fgu,2.3,028910170936 =====DISK INFORMATION===== .... </code></pre>
