several arguments together

several arguments together
Hello guys,
you may help me on this :
I want to search thru many files if a sentence or a string exists and printout the lines where this is present by calling a script like :
loc "arg1 arg2 arg3 arg4"
where arg1 arg2 arg3 arg4 would be in fact the sentence separated with blanks...
In my loc script, I would have to count the number of arguments and store them as a sentence into one single variable i guess, like :
sentence=`arg1 arg2 arg3 arg4`
But, as arguments number is undefined, how can i insure this to work in any case ?
Any idea ?
Thanks,
homefp

I have a SNMP agent that sends three arguments to the script to get a value at the end. The first is the LeafNumber, second is the request type (SET, GET, GETNEXT), and the last is a string that represents some value to be set(used only for set requests).
The agent string looks like this:

shevek::istring(3) Library Functions Manual shevek::istring(3) NAME
shevek::istring - shevek::istring is a C++ version of scanf. SYNOPSIS
#include <iostring.hh> Public Member Functions istring () Create a new istring with no data. istring (Glib::ustring const &str) Create a new istring with data. void init (Glib::ustring const &str) Set new data to an existing istring. void push () Push the current position to the stack so it can be restored later. int pop (bool keep=false) Pop the last pushed position from the stack. void reset () Set the current position to 0, but don't change the stack. Glib::ustring rest () const Get remaining string. void skip (Glib::ustring::size_type p) Skip some characters. bool operator() (Glib::ustring const &format) Read a constant string from the input. template<typename T1 > bool operator() (Glib::ustring const &format, T1 &arg1) Read a string containing one argument from the input. template<typename T1 , typename T2 > bool operator() (Glib::ustring const &format, T1 &arg1, T2 &arg2) Read a string containing two arguments from the input. template<typename T1 , typename T2 , typename T3 > bool operator() (Glib::ustring const &format, T1 &arg1, T2 &arg2, T3 &arg3) Read a string containing three arguments from the input. template<typename T1 , typename T2 , typename T3 , typename T4 > bool operator() (Glib::ustring const &format, T1 &arg1, T2 &arg2, T3 &arg3, T4 &arg4) Read a string containing four arguments from the input. template<typename T1 , typename T2 , typename T3 , typename T4 , typename T5 > bool operator() (Glib::ustring const &format, T1 &arg1, T2 &arg2, T3 &arg3, T4 &arg4, T5 &arg5) Read a string containing five arguments from the input. template<typename T1 , typename T2 , typename T3 , typename T4 , typename T5 , typename T6 > bool operator() (Glib::ustring const &format, T1 &arg1, T2 &arg2, T3 &arg3, T4 &arg4, T5 &arg5, T6 &arg6) Read a string containing six arguments from the input. template<typename T1 , typename T2 , typename T3 , typename T4 , typename T5 , typename T6 , typename T7 > bool operator() (Glib::ustring const &format, T1 &arg1, T2 &arg2, T3 &arg3, T4 &arg4, T5 &arg5, T6 &arg6, T7 &arg7) Read a string containing seven arguments from the input. template<typename T1 , typename T2 , typename T3 , typename T4 , typename T5 , typename T6 , typename T7 , typename T8 > bool operator() (Glib::ustring const &format, T1 &arg1, T2 &arg2, T3 &arg3, T4 &arg4, T5 &arg5, T6 &arg6, T7 &arg7, T8 &arg8) Read a string containing eight arguments from the input. Static Public Member Functions template<typename T > static T direct (Glib::ustring const &data, Glib::ustring const &format, T def=T()) Read a variable from given data and return it. Detailed Description shevek::istring is a C++ version of scanf. It uses templates to allow expanding it to user-defined types, but it still uses a format string to make it better translatable. Member Function Documentation template<typename T > static T shevek::istring::direct (Glib::ustring const &data, Glib::ustring const &format, Tdef = T ()) [inline, static] Read a variable from given data and return it. This allows using a shevek::istring in an expression without the need to create a new variable for it. If the input doesn't match the format, def is returned. int shevek::istring::pop (boolkeep = false) Pop the last pushed position from the stack. If keep is true or not given, the current position is restored to the last position. If it is false, the current position is not changed.
