脚本-Linux常用命令行工具介绍

查看切割
find ./ -name '*.mp4' | cut -d '/' -f3 | sort
按行合并文档
paste -s /mnt/json/*.json >> /mnt/a.json
查找并cp
find ./ -type f -name '*.bmp' | grep -v ".*.src.*.bmp" | grep -v ".*.face.*.bmp" | xargs -i cp {} /mnt/pic2/

杀死redis进程
#获取redis pid
redis_pid=$(ps -ef | grep 6379 | grep -v grep | awk '{print $2}')
#判断redis pid是不是存在
if [ ! $redis_pid ]; then
  echo 'redis pid does not exist.'
else
  echo 'redis pid exists.'
  kill -9 $redis_pid
fi
# 打印redis pid
ps -ef | grep 6379 | grep -v grep | awk '{print $2}'

脚本所在路径
SHELL_PATH=$(cd $(dirname $0);pwd)
cd $SHELL_PATH/..

# shell脚本，根据字符串查找所有进程对应的目录
#!/bin/bash
# 通过字符串查找所有进程
processes=$(ps aux | grep $1 | grep -v grep | awk '{print $2}')
# 遍历进程并输出它们的目录
for process in $processes; do
    # 获取进程的工作目录
    cwd=$(readlink /proc/$process/cwd)
    echo "Process $process is running in $cwd"
done


kill $(ps aux | grep "your_string" | grep -v grep | awk '{print $2}')
或
#!/bin/bash
# 通过字符串查找所有进程
processes=$(ps aux | grep $1 | grep -v grep | awk '{print $2}')
# 遍历进程并杀死它们
for process in $processes; do
    echo "Killing process $process"
    kill -9 $process
done

shell脚本，根据字符串查找所有进程并杀死， 一行
kill $(ps aux | grep "your_string" | grep -v grep | awk '{print $2}')
