Shell脚本--常用脚本

1.shell脚本查询指定进程并杀死

#!/bin/bash


pids=$(ps -ef | grep "${name}" | grep -v "$0" | grep -v grep | awk '{print $2}')    # name是进程名称
for pid in ${pids}
do
kill -9 ${pid}
done

 2.gcc编译代码

#!/bin/bash


#set -x
_file=$1
_bin=${_file%.*}
_suffix=${_file#*.}

echo "file:${_bin} suffix:${_suffix}"
if [[ -x ${_file} ]]; then
    if [[ -e ${_file}.c ]]; then
        gcc -g ${_file}.c -o ${_bin}
    elif [[ -e ${_file}.cpp ]]; then
        g++ -g -std=c++11 ${_file}.cpp -o ${_bin}
    fi
elif [[ -e ${_file} ]]; then
    if  [[ ${_suffix} == "c" ]]; then
        gcc -g ${_file} -o ${_bin}
    else
        g++ -g -std=c++11 ${_file} -o ${_bin}
    fi
fi
