简化gdb脚本

　　每次调试都是先PS x|grep xxxx ，然后gdb attach pid ，太麻烦了！写了个烂脚本给自己减负～～～

#!/bin/bash

#check num of argv

if [[ $# -ne 1 ]]; then
    echo 'err: argv num!'
    exit
fi

#deal string
var_argv=$1
var_name=`echo $var_argv| tr -d "/"` 
var_pid_name=${var_argv}'IM'${var_name}

ret_var=`ps -x |grep $var_pid_name |grep -v grep | awk '{print $1}'`

#string to array
arr_out=()
arr=(${ret_var/' '/ })  
  
for i in ${arr[@]}  
do  
    arr_out[${#arr_out[@]}]=$i
done  


#Determines that the string length

len_arr=${#arr_out[@]}

if [[ $len_arr -ne 1 ]];then
    echo 'Too manay pid!'
    for pid in ${arr_out[*]}
    do  
        echo $pid
    done
    exit
fi

echo 'curpid:' $ret_var
gdb attach $ret_var
