lists all of the signals your system supports, both name and number. /usr/include/sys/signal.h also has them if you want to know what they mean - as Don C mentioned.
The kill -l option originated in the C shell and was standardized by the POSIX standards and the Single UNIX Specification many years ago. The standard requires that the -l option on a command line with no operands list the names of the signals known on that system, but does not allow the signal numbers to also be included in that list. Older versions of the Korn shell did print both names and numbers, but David agreed with other developers writing the standards that having the numbers made it more difficult for shell script writers to process the output of this option. Recent versions of the ksh utility's kill built-in do not print the signal numbers.
On older systems where the trap special built-in utility only accepts signal numbers (not signal names), it was common practice for the kill utility not to recognize the -l option either.
You can also use current versions of the kill utility to translate a signal number into a signal name. For example:
will either print TERM or SIGTERM on systems where signal number 15 is SIGTERM. Obviously, you can also put the above command in a loop to map signal numbers to signal names on your system.
