SIGTERM
From Wikipedia, the free encyclopedia
| Description: | Termination signal |
|---|---|
| Default action: | Abnormal termination of the process |
| SA_SIGINFO macros | |
| None | |
On POSIX-compliant platforms, SIGTERM is the signal sent to computer programs to request termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms, however on the vast majority of systems, SIGTERM is signal #15.
[edit] Etymology
SIG is a common prefix for signal names. TERM is an abbreviation for terminate.
[edit] Usage
SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process, but unlike the SIGKILL signal, it can be caught and interpreted (or ignored) by the process.
