# trap 'echo cmd=$BASH_COMMAND' DEBUG # trap 'echo Ctrl-C pressed' SIGINT cmd=trap 'echo Ctrl-C pressed' SIGINT # while [ 1 ]; do > true done cmd=[ 1 ] cmd=true cmd=[ 1 ] cmd=true ... cmd=[ 1 ] cmd=true cmd=[ 1 ] cmd=true ^CCtrl-C pressed # whoami root # echo $BASH_COMMAND true # trap 'echo cmd=$BASH_COMMAND' DEBUG # whoami root # echo $BASH_COMMAND true
As you can see, it prints out everything I type on the console before the "while [ 1 ]" thing. After running the infinite loop and press Ctrl-C, trap DEBUG doesn't work anymore, and echo $BASH_COMMAND always prints out true. Is it a bash bug? Thanks.
