| [ CnUnix ] in KIDS 글 쓴 이(By): dal (ⓓⓐⓛ *) 날 짜 (Date): 1994년09월18일(일) 11시47분04초 KDT 제 목(Title): debussy님 control-c trap 이란 걸 써보시죠. korn shell 에 있는건데. 예를 들어서 trap 'echo hi' 2 하시면 control-c 할때 hi라고 대신 나오죠. man ksh를 카피해서 오리면 trap [ arg ] [ sig ] ... arg is a command to be read and executed when the shell receives signal(s) sig. (Note that arg is scanned once when the trap is set and once when the trap is taken.) Each sig can be given as a number or as the name of the signal. Trap commands are executed in order of signal number. Any attempt to set a trap on a signal that was ignored on entry to the current shell is ineffective. An attempt to trap on signal 11 (memory fault) produces an error. If arg is omitted or is -, then all trap(s) sig are reset to their original values. If arg is the null string then this signal is ignored by the shell and by the commands it invokes. If sig is ERR then arg will be executed whenever a command has a non-zero exit code. This trap is not inherited by functions. If sig is 0 or EXIT and the trap statement is executed inside the body of a function, then the command arg is exe- cuted after the function completes. If sig is 0 or EXIT for a trap set outside any function then the com- mand arg is executed on exit from the shell. The trap command with no arguments prints a list of commands associated with each signal number. 그리고.. 앙마아저씨가 말씀하신거 같이.. signal.h를 보면 번호 설명이 나와있으니까.. .. #define SIGINT 2 /* interrupt, generated from terminal special char */ #define SIGTSTP 18 /* (@) interactive stop */ 같이 번호를 바꾸시면 되고. 달님 |
