Variable Validation

Hi Guys,

I am getting count from a file (pipe delimited).

Code:
"23"|"9896"|"20090101"|"New Load"

I am using the following code to get the first two counts.

Code:
CtrlFileByte=`/bin/gawk -F"|" '{ print $1 }' $ControlFile`;
CtrlFileCnt=`/bin/gawk -F"|" '{ print $2 }' $ControlFile`;

But the problem is file Byte is not mandatory as well as file count.

So, if it is present then i have execute a check otherwise i just skip it an d check for the other one.

I am using the following code for it. But it is throwing an error.

Code:
if [ `echo $CtrlFileCnt|tr -d ' '` = '' ] && [ `echo $SrcFileByte|tr -d ' '` = '' ] ; then
echo "File Count Check and Byte Count Check is Skipped";
else
if [ `echo $CtrlFileCnt|tr -d ' '` = '' ]; then
 echo "File Count Check is skipped";
 else 
 if [ `echo $SrcFileByte|tr -d ' '` != '' ] ; then
 echo "File Byte Check is skipped";
  else
  echo "Both are checked";
fi
fi
fi

But it is working fine when both variables are having values. But when one of them is misssing, then it is throwing an error.

Can somebody help me out here..

Cheers!!!!!!!!!!!!


This code is working Smilie

Code:
if [ "${CtrlFileCnt}" = "" ] && [ "${SrcFileByte}" = "" ] ; then
echo "File Count Check and Byte Count Check is Skipped";
elif [ "${CtrlFileCnt}" = "" ]; then
 echo "File Count Check is skipped";
elif [ "${SrcFileByte}" = "" ] ; then
 echo "File Byte Check is skipped";
  else
  echo "Both are checked";
fi

NAME
paps - UTF-8 to PostScript converter using Pango SYNOPSIS
paps [options] files... DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves through the pango ft2 backend. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. --landscape Landscape output. Default is portrait. --columns=cl Number of columns output. Default is 1. --font=desc Set the font description. Default is Monospace 12. --rtl Do rtl layout. --paper ps Choose paper size. Known paper sizes are legal, letter, a4. Default is A4. --bottom-margin=bm Set bottom margin in postscript points (1/72 inch). Default is 36. --top-margin=tm Set top margin. Default is 36. --left-margin=lm Set left margin. Default is 36. --right-margin=rm Set right margin. Default is 36. --help Show summary of options. --header Draw page header for each page. --markup Interpret the text as pango markup. --encoding=ENCODING Assume the documentation encoding is ENCODING. --lpi Set the lines per inch. This determines the line spacing. --cpi Set the characters per inch. This is an alternative method of specifying the font size. --stretch-chars Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops behaviour. AUTHOR
