[Crash-utility] a strange thing

hi, all When i used crash in a bash script file, a strange thing happened. step 1: I created a bash script file: test.sh and put the following line to the file. crash -i inputfile > stdout [root@rhel51rc2 gid]# echo "crash -i inputfile > stdout" > test.sh step 2: I ran the bash script file. But i forgot to create the inputfile, so the tesh.sh process hanguped. [root@rhel51rc2 gid]# chmod 777 test.sh [root@rhel51rc2 gid]# ./test.sh step 3: I killed the process in another terminal. [root@rhel51rc2 gid]# ps aux | grep crash root 2290 1.3 2.6 156064 89648 pts/3 S+ 16:53 0:03 crash -i inputfile root 2310 0.0 0.0 61280 1792 pts/4 S+ 16:56 0:00 grep crash [root@rhel51rc2 gid]# kill -9 2290 [root@rhel51rc2 gid]# step 4: I continued to use the first terminal. The strange thing happend, that I could not see the command(ex. ls) I inputed, but when I pressed Enter, It was executed. what's wrong? [root@rhel51rc2 gid]# ./test.sh ./test.sh: line 1: 2290 Killed crash -i inputfile >stdout [root@rhel51rc2 gid]# a.out CVS gid.c gid.stp Makefile run.sh stdout test.sh [root@rhel51rc2 gid]# Best Regards, yang
