CPU & Memory how to get the string stored in a variable in a line???
Hi all,

I want to search for a data type in a line.For this in a loop i am checking for $DATA_TYPE in a line using grep.But grep is not able to find when i give this.
Can any one tell me how to check string in $DATA_TYPE variable in line usign grep (or) any other way to do the above task.

declare -a TYPES_LIST
declare -a EXIST_FLAG=0
TYPES_LIST[0]="char"
TYPES_LIST[1]="int"
TYPES_LIST[2]="float"
TYPES_LIST[3]="double"


for DATA_TYPE in "${TYPES_LIST[@]}"
do

EXIST_FLAG=`echo $CHECK_LINE|grep -c ':$[ *]"$DATA_TYPE"'

if test $EXIST_FLAG -gt 0 ; then
echo $CHECK_LINE
break
fi
done

Here CHECK_LINE="580:$ char *tablename;"

Thanks in Advance

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.
