Следую ману:
✘ kek@archlinux ~ kill -l
HUP INT QUIT ILL TRAP IOT BUS FPE KILL USR1 SEGV USR2 PIPE ALRM TERM STKFLT CHLD CONT STOP TSTP TTIN TTOU URG XCPU XFSZ VTALRM PROF WINCH POLL PWR SYS
тут верно, краткая таблица. А вот если хочу с кодами, то большая -L
-L, --table
Similar to -l, but it will print signal names and their corresponding numbers.
✘ kek@archlinux ~ kill -L
kill: unknown signal: SIGL
kill: type kill -l for a list of signals
Не готов!
