Default Action Description: sighup terminates the process and ends the terminal line.
SIGINT terminates process interruption
Sigquit creates a core file to terminate the process and generates a Core File
Invalid Command for creating core file in sigill
Sigtrap creates core file tracking self-traps
Sigbus Core File bus creation error
Invalid SIGSEGV Core File segment creation error
An error occurred while creating the core file floating point in sigfpe.
Sigiot creates Core File Execution I/O self-traps
Sigkill terminate the process and kill the process
Sigpipe terminates a process and writes data to an unread process pipeline.
When sigalarm terminates the process Timer
Sigterm termination process software termination signal
Sigstop stop signal of non-terminal stop Process
Sigtstp stop signal from the process Terminal
Sigcont ignores the signal and continues a stopped process.
Sigurg ignores signal I/O emergency signals
Sigio can ignore the I/O on the signal Descriptor
Sigchld ignores the signal and notifies the parent process when the child process stops or exits.
Sigttou stops the process Background Process Writing Terminal
Sigttin stops the process Background process read Terminal
Sigxgpu termination process CPU timeout
The length of the sigxfsz termination process file is too long.
Sigwinch ignores changing signal window size
Sigprof termination process statistical distribution when timer is used
SIGUSR1 termination process user-defined signal 1
Sigusr2 termination process user-defined Signal 2
When sigvtalrm terminates the virtual timer of the process
