Thanks a lot....Smilie

total=`echo $numone + $numtwo | bc`

worked fine.

There is also one more prob......The variable sometimes contains "" attached to it also eg "23.45".
How to handle this in the addition?It is throwing an error"syntax error on line 1 stdin"

NAME
cgiparse - CGI argument parsing utility SYNOPSIS
cgiparse [mode] [-enc {none | url | mime | dacs}] [-in filename] [-d] [-nonewline] [-qs query-string] [-copy filename] [[-n name filename]...] DESCRIPTION
This program is part of the DACS suite. It is a stand-alone program that neither accepts the usual DACS command line options (dacsoptions) nor accesses any DACS configuration files. This utility is used by web-based scripts (shell scripts in particular) to obtain their CGI arguments, which can be obtained from a URI's query component or in an encoded entity-body read from the standard input (as with the POST method). The form content types[1] application/x-www-form-urlencoded and multipart/form-data are both understood. The program has several different modes of operation, one of which may be specified by the first command line argument. cgiparse combines query arguments found in the QUERY_STRING environment variable with arguments found in the message body it reads from the standard input. If an argument name is duplicated the result is indeterminate. OPTIONS
The mode may be one of the following: -arg variable-name Emit the value of the CGI argument variable-name, then exit. If there is no such argument, the exit status will be 1 instead of 0. -targ variable-name Test if the CGI argument variable-name exists. If there is no such argument, the exit status will be 1, otherwise it will be 0. -html Emit an HTML document that lists the CGI argument names and their values. -one Emit a listing of the CGI argument values (without the names). -sh Emit CGI arguments as a single line in the format: variable-name='variable-value'; [...] It is an error if any variable-name or variable-value is syntactically unsuitable for this format. The returned string can be used as the argument to eval to set the CGI arguments as shell variables. -text Like -html except emit text. This is the default. With this mode, the program's stdout is usually written to a file. Each line of the file has the format: variable-name variable-value (a space separates the name from the corresponding value). The file is typically read by a script to obtain the arguments, or cgiparse can be run with the -in flag to retrieve an argument. Additionally, cgiparse recognizes these options: If writing the parsed CGI arguments (-text), encode the argument value using the specified method: url means URL encoding, mime means MIME base-64 encoding, and dacs means DACS base-64 encoding. For details about these encodings, please see dacs.exprs(5)[2]. The default is none, which means that no encoding is performed (use this only when you are sure this cannot cause a problem). If reading the parsed CGI arguments (-in), decode the argument values using the specified method. The default is none, which means that no decoding is performed; if the arguments were encoded, they will be returned in that encoding, but other than this case the decoding method must match the encoding method previously used or an error is likely to occur. -qs query-string Instead of using the environment variable QUERY_STRING to get a query component, use query-string. -nonewline With -arg, do not emit a newline after printing an argument value. -d Enable debugging output. -copy filename Append the input stream to filename. This can be useful for debugging purposes. -in filename Instead of parsing CGI arguments, read variable name/value pairs (as produced by the -text flag) from filename. If filename is "-", stdin is read. -n name filename If parsing succeeds, and there is a MIME body part with a name exactly matching name, then: o if the content disposition is multipart/form-data, write the content as quoted-printable text to filename; o if the content disposition is base64, write the decoded content to filename; o otherwise the content is written verbatim to filename. If the output file exists it is truncated. EXAMPLES
The following shell script demonstrates one way of using cgiparse. #! /bin/sh tmpfile=/tmp/cgiparse.$$ cgiparse > ${tmpfile} chmod 0600 ${tmpfile} echo "Context-Type: text/plain" echo "" done= while [ "${done}x" = x ] do a= b= read a b if [ $? = 1 ] then done=1 break else echo "Arg: ${a}" echo "Is: ${b}" fi done < ${tmpfile} rm -f ${tmpfile} exit 0 The following code fragment uses cgiparse to save and then look up its CGI arguments: #! /bin/sh tmpfile=/tmp/cgiparse.$$ trap 'rm -f ${tmpfile}; exit 1' EXIT 1 2 3 13 15 cgiparse -enc mime > ${tmpfile} chmod 0600 ${tmpfile} mode=`cgiparse -in ${tmpfile} -enc mime -arg MODE` target=`cgiparse -in ${tmpfile} -enc mime -arg TARGET` The following script will print "1 2 3" to its standard output: #! /bin/sh args=`cgiparse -sh -qs "a=1&b=2&c=3"` eval "$args" echo "$a $b $c" DIAGNOSTICS
The program exits 0 if everything was fine, 1 if an error occurred. BUGS
There do not appear to be any official recommendations concerning how to handle apparently "malformed" CGI query strings that do not look like a sequence of name=value pairs. The parsing routines that cgiparse uses will flag an error if they see strings containing a component like "=foo", for example, although "foo=" is fine. SEE ALSO
