Question two grep in one script doesn't work?
Hi there,
the following script doesn't work. the first part works, then the second 'grep' fails with ': not found'. However, if I take out the second part (starting with the grep command) and put in a seperate script, it works.
everyone know what's wrong here? no two 'grep' in one script, that sounds weird?

Code:
#!/bin/ksh
summary1=0
summary2=0
grep 'Execution Time' test1_12.5.txt |awk '{print $3}' |sed 's/\([0-9]*\).*/\1/' |\
while read num1
do
#echo $num1
summary1=`expr $summary1 + $num1 `
done
echo "Total Execution Time: " $summary1
grep 'Total actual I/O cost for this command' test1_12.5.txt |awk '{print $8}' |sed 's/\([0-9]*\).*/\1/' |\
while read num2
do
echo $num2
summary2=`expr $summary2 + $num2 `
done
#echo "Total actual I/O cost: " $summary2

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
