linux命令拦截

1. ~/.ucm/record_command.sh

#!/usr/bin/bash
record_cmd(){
printf "recording command:[$1]\n"
}

if [ $2 == 0 ];then
record_cmd "$1"
else
record_cmd "$1"
printf "will ignore exec [$1].\n";
fi

 2. ~/.ucm/is_cmd_ban.sh

#!/usr/bin/bash
if [[  "$1" == "aa"* ]];then
    echo 1;
fi

3. 在.profile后面加上

#ucm linux command interceptor
#set -T
#shopt -s extdebug   如果执行的是禁用命令，则shopt -s extdebug，否则shopt -u extdebug
trap 'a=0; if [[ $($HOME/.ucm/is_cmd_ban.sh "$BASH_COMMAND") == 1 ]]; then a=1; shopt -s extdebug; else shopt -u extdebug; fi; $HOME/.ucm/record_command.sh "$BASH_COMMAND" $a; false;' DEBUG
