awk command not working from the shell script
Hi,

When i run the below command i am able to get the output.

Code:
awk '/BEGIN DSSUBRECORD/{c=3;next}c-->0' abc.txt | 
awk '/END DSSUBRECORD/{exit}{print}' |
awk '/Owner/{exit}{print}' | 
awk '{n2=n1;n1=n;n=$0;if(NR%3==0){printf"%s,%s,%s\n",n2,n1,n}}'

Output:
Code:
 Name "file_name",          Prompt "Enter the file name",          ParamType "1"
 Name "file_name1",         Prompt "Enter the file name",          ParamType "1"

==================================================================================================== ========

I want run this command for multiple files. so i wrote a script to check.
When i run this command using a sheel script, it is not working.

I have the below error message:

Code:
a=0
cnt=2
a1="abc.txt"
while [ $a -ne $cnt ]
do
bp1="awk '/BEGIN DSSUBRECORD/{c=3;next}c-->0'  | 
awk '/END DSSUBRECORD/{exit}{print}' |
awk '/Owner/{exit}{print}' | 
awk '{n2=n1;n1=n;n=$0;if(NR%3==0){printf"%s,%s,%s\n",n2,n1,n}}'"
echo " "  `$bp1`
a=$(( $a + 1 ))
done
 
 Syntax Error The source line is 1.
 The error context is
                 >>> /BEGIN <<<
 awk: 0602-500 Quitting The source line is 1.



input is a txt file and it is a big file.i tired all the possibilties to skip the '/' and $0 values in the command.
Any help would be appreciated.

Thanks

shtool-path

SHTOOL-PATH.TMP(1)					      GNU Portable Shell Tool						SHTOOL-PATH.TMP(1)

NAME

       shtool-path - GNU shtool command dealing with shell path variables

SYNOPSIS

       shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

DESCRIPTION

       This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments.  It
       prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.

OPTIONS

       The following command line options are available.

       -s, --suppress
	   Supress output. Useful to only test whether a program exists with the help of the return code.

       -r, --reverse
	   Transform a forward path to a subdirectory into a reverse path.

       -d, --dirname
	   Output the directory name of str.

       -b, --basename
	   Output the base name of str.

       -m, --magic
	   Enable advanced magic search for ""perl"" and ""cpp"".

       -p, --path path
	   Search in path. Default is to search in $PATH.

EXAMPLE

	#   shell script
	awk=`shtool path -p "${PATH}:." gawk nawk awk`
	perl=`shtool path -m perl`
	cpp=`shtool path -m cpp`
	revpath=`shtool path -r path/to/subdir`

HISTORY

       The GNU shtool path command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
       over into GNU shtool.
