I'm using the trap command to capture any signals received whilst my script is running.
How's the best way of writing the signal and any other error messages to a file/error log' without having to type '2>$1' on the command line after the script name?

FBB::level(3bobcat) Log-manipulator FBB::level(3bobcat)
NAME
FBB::level - Manipulator setting the log-level of FBB::Log objects
SYNOPSIS
#include <bobcat/level>
Linking option: -lbobcat
DESCRIPTION
An FBB::level object is used to change the log-level of FBB::Log objects. It may be inserted into an empty FBB::Log object (i.e., immedi-
ately before a time stamp might be inserted by the FBB::Log object itself). This is the case after terminating a log message using a
std::endl or
character.
NAMESPACE
FBB
All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.
INHERITS FROM
-
CONSTRUCTORS
o level(size_t nextLevel):
The constructor is normally used in a insertion statement where it is inserted into an FBB::Log object. The copy constructor is
available, but normally not used.
OVERLOADED OPERATOR
o std::ostream &::operator<<(std::ostream &str, FBB::level const &):
The std::ostream &str object should be an empty FBB::Log object. In that case the value stored in the FBB::level object is used to
set the FBB::Log object's next message level. If the std::ostream object is not an FBB::Log object or if the object is not empty,
the function returns str without further action.
EXAMPLE
FBB::Log log;
log << FBB::level(3) << "Message at level 3
";
FILES
bobcat/level - defines the class interface.
SEE ALSO
