On POSIX-compliant platforms, SIGQUIT is the signal sent to a process by its controlling terminal when the user requests that the process perform a core dump.[1] The symbolic constant for SIGQUIT is defined in the header file signal.h; on the vast majority of systems it is signal #3.
SIGQUIT can usually be induced with Control-\. On Linux, one may also use Ctrl-4 or, on the virtual console, the SysRq key.
[edit] Etymology
SIG is a common prefix for signal names. QUIT stands for quit.
