我有这个init.d脚本，我正在检查应用程序的状态，预期的输出应该是 ＆＃34;应用程序正在运行PID：XXXX＆＃34;
无论如何，我会告诉你我使用过的代码：
ps -ef|grep -v grep |grep Jazz |grep -v "Jazz status"|awk '{ if ( $2 != "") print "Jazz Running with PID:",$2"; else print "Jazz not running";}'
当我在终端上运行时，我得到以下输出：
Jazz Running with PID: 6261
Jazz Running with PID: 30077
当我删除print语句并输出$ 2时，我得到以下输出：
#ps -ef|grep -v grep |grep Jazz |grep -v "Jazz status"|awk '{ if ( $2 != "") print $2}'
300077
我希望输出为
Jazz Running with PID: 300773
我很难过为什么我在第一种情况下得到两个PID？ P.S第一个PID不断变化，类似于向我显示命令本身的PID。
修改
输出：ps -ef|grep Jazz

netcool 19735 19678 0 14:50 pts/0 00:00:00 grep Jazz
修改 我使用的完整init.d脚本：
#!/bin/sh
USER="xxxxxxx"
PASSWORD="xxxxxx"
start() {
su - netcool -c "/opt/IBM/tivoli/jazzSM/profile/bin/startServer.sh server1"
RETVAL=$?
return $RETVAL
}
stop() {
su - netcool -c "/opt/IBM/tivoli/jazzSM/profile/bin/stopServer.sh server1 -username ${USER} -password ${PASSWORD}"
RETVAL=$?
return $RETVAL
}
status() {
ps -ef|grep -v grep |grep Jazz |grep -v awk |grep -v "Jazz status" |awk '{ if ( $2!= "") print "Jazz is running with PID:",$2; else print "Jazz is not running";}'
#pid=$(pgrep -f Jazz) && echo "Jazz Running with PID: $pid" || echo "Jazz is not running"
}
case $1 in
"start")
start
;;
"stop")
stop
;;
"status")
status
;;
"restart"|"reload")
stop
start
;;
*)
echo "usage: $0 {start|stop|status|restart|reload}"
RETVAL=1
esac
exit 0
希望这有帮助
更新 基于@jlliagre建议，运行以下命令仍然给了我多个PID作为输出：
[root@hjkpnlinst04 ~]# pid=$(pgrep -f jazzSM) && echo "Jazz Running with PID: $pid" || echo "Jazz is not running"
Jazz Running with PID: 12744
13176
13299
现在我正在运行这个命令，它似乎在进程运行时给了我所需的输出，但是没有给我＆＃34; else＆＃34;进程未运行时的输出：
ps -ef|grep -v grep |grep Jazz |grep -v awk |grep -v "Jazz status" |awk '{ if ( $2!= "") print "Jazz is running with PID:",$2; else print "Jazz is not running";}'
答案 0 :(得分：1)
该命令应该有效（假设pgrep可用）：
pid=$(pgrep -f JazzSMNode01Cell) && echo "Jazz Running with PID: $pid" || echo "Jazz is not running"
答案 1 :(得分：0)
你最有可能找到awk。你排除grep，但不是awk。 更好的方法是使用pgrep命令，例如：
echo "java is running with pids ", `pgrep java`
将列出正在运行Java进程的所有pid。它仅查看过程映像名称，而不是命令行。我不确定pgrep是多么便携，但它在Linux，FreeBSD和OS X上都有，对我来说已经足够了。
但是看看你更新的答案我发现你正在寻找命令行关键字，所以就像@jlliagre建议的那样，你应该使用-f switch。 pgrep的优势在于它可以排除自身，与awks和greps链不同。
