## List of signals used to initialize ksh's signal table (see trap.c# and siglist.sh).## Note that if a system has multiple defines for the same signal# (eg, SIGABRT vs SIGIOT, SIGCHLD vs SIGCLD), only the first one# will be seen, so the order in this list is important.#    HUP    Hangup    INT    Interrupt    QUIT   Quit    ILL    Illegal instruction    TRAP   Trace trap# before IOT (ABRT is posix and ABRT is sometimes the same as IOT)    ABRT   Abort    IOT    IOT instruction    EMT    EMT trap    FPE    Floating point exception    KILL   Killed# before BUS (linux doesn't really have a BUS, but defines it to UNUSED)    UNUSED Unused    BUS    Bus error    SEGV   Memory fault    SYS    Bad system call    PIPE   Broken pipe    ALRM   Alarm clock    TERM   Terminated    STKFLT Stack fault    IO     I/O possible    XCPU   CPU time limit exceeded    XFSZ   File size limit exceeded    VTALRM Virtual timer expired    PROF   Profiling timer expired    WINCH  Window size change    LOST   File lock lost    USR1   User defined signal 1    USR2   User defined signal 2    PWR    Power-fail/Restart    POLL   Pollable event occurred    STOP   Stopped (signal)    TSTP   Stopped    CONT   Continued# before CLD (CHLD is posix and CHLD is sometimes the same as CLD)    CHLD   Child exited    CLD    Child exited    TTIN   Stopped (tty input)    TTOU   Stopped (tty output)    INFO   Information request    URG    Urgent I/O condition# Solaris (svr4?) signals    WAITING No runnable LWPs    LWP	   Inter-LWP signal    FREEZE Checkpoint freeze    THAW   Checkpoint thaw    CANCEL Thread cancellation
