我经常需要在编程期间终止一个进程。
我现在的做法是:
[~]$ ps aux | grep 'python csp_build.py'
user 5124 1.0 0.3 214588 13852 pts/4 Sl+ 11:19 0:00 python csp_build.py
user 5373 0.0 0.0 8096 960 pts/6 S+ 11:20 0:00 grep python csp_build.py
[~]$ kill 5124
如何自动提取进程id并在同一行中杀死它?
是这样的:
[~]$ ps aux | grep 'python csp_build.py' | kill <regex that returns the pid>

如果你想主要在awk中完成，试试吧
for i in $(jot 5); do
(python3 -c 'import sys; [ print(_) for _ in sys.stdin ]' ) & done;
sleep 1; ps aux | {m,g}awk '
/[p]ython/ {
_=(_)" "$2
} END {
system("echo \47 kill "(_)" \47")
system( "kill -9 " _) }'
[302] 14236
[303] 14237
[304] 14238
[305] 14239
[306] 14240
[303] + suspended (tty input) ( python3 -c 'import sys; [ print(_) for _ in sys.stdin ]'; )
[305] + suspended (tty input) ( python3 -c 'import sys; [ print(_) for _ in sys.stdin ]'; )
[304] + suspended (tty input) ( python3 -c 'import sys; [ print(_) for _ in sys.stdin ]'; )
[302] + suspended (tty input) ( python3 -c 'import sys; [ print(_) for _ in sys.stdin ]'; )
[306] + suspended (tty input) ( python3 -c 'import sys; [ print(_) for _ in sys.stdin ]'; )
kill 14239 14237 14236 14240 14238
[305] killed ( python3 -c 'import sys; [ print(_) for _ in sys.stdin ]'; )
[303] killed ( python3 -c 'import sys; [ print(_) for _ in sys.stdin ]'; )
[306] + killed ( python3 -c 'import sys; [ print(_) for _ in sys.stdin ]'; )
[304] - killed ( python3 -c 'import sys; [ print(_) for _ in sys.stdin ]'; )
[302] + killed ( python3 -c 'import sys; [ print(_) for _ in sys.stdin ]'; )
其他回答
ps -o uid,pid,cmd|awk '{if($1=="username" && $3=="your command") print $2}'|xargs kill -15
试着用
ps aux | grep 'python csp_build.py' | head -1 | cut -d " " -f 2 | xargs kill
我的任务是杀死所有与regexp匹配的放在特定目录中的内容(在selenium测试之后，并不是所有内容都停止了)。这招对我很管用:
for i in `ps aux | egrep "firefox|chrome|selenium|opera"|grep "/home/dir1/dir2"|awk '{print $2}'|uniq`; do kill $i; done
我使用gkill processname，其中gkill是以下脚本:
cnt=`ps aux|grep $1| grep -v "grep" -c`
if [ "$cnt" -gt 0 ]
then
echo "Found $cnt processes - killing them"
ps aux|grep $1| grep -v "grep"| awk '{print $2}'| xargs kill
else
echo "No processes found"
fi
注意:它不会杀死命令行中有“grep”的进程。
根据https://stackoverflow.com/a/3510879/15603477的回答。小的优化。
ps aux | grep 'python csp_build.py' | head -1 | tr -s ' ' | cut -d " " -f 2 | xargs kill
使用tr -s ' '将多个空白(如果有的话)压缩为一个空白。
