我的脚本:用nohup执行命令很困惑?
#!/bin/bash
. /home/was/.bash_profile
export PATH=/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/was/bin:/wasdata/oracle/10.2.0/client_1/bin:
sqlplus "mon_system/[email protected]" <<eof
set echo off
set feedback off
set serveroutput on
set term off
set sqlprompt ""
set linesize 200
spool /wasdata/scripts/systeminf/tmp-was-restart.sh
exec prc_auto_restart
eof
sed -i '/prc_auto_restart/d' tmp-was-restart.sh
/wasdata/scripts/systeminf/tmp-was-restart.sh
cat /dev/null>/wasdata/scripts/systeminf/tmp-was-restart.sh
的过程是: 1登录到数据库中执行一个过程“prc_auto_restart” 2的步骤将输出“/wasdata/scripts/systeminf/tmp-was-restart.sh “ 3执行 ”/wasdata/scripts/systeminf/tmp-was-restart.sh“
的tmp-was-restart.sh会喜欢:
ssh [email protected] "ps -ef|grep was1.*WebSphere.*c01_ship_s01|grep -v "grep">>kill.log;ps -ef|grep was1.*WebSphere.*c01_ship
_s01|grep -v "grep"|awk '{print \"kill -9 \" \$2}'|sh"
当我执行SCRI PT直接的脚本工作:
[[email protected] systeminf]$ ./prod-auto-restart.sh

但是当我使用的nohup执行脚本:
[[email protected] systeminf]$ nohup prod-auto-restart.sh &
[1] 29983
[[email protected] systeminf]$ nohup: appending output to `nohup.out'
[1]+ Stopped nohup prod-auto-restart.sh
[[email protected] systeminf]$
[[email protected] systeminf]$
[[email protected] systeminf]$ ps -ef|grep autp
was 30014 27492 0 16:33 pts/4 00:00:00 grep autp
[[email protected] systeminf]$ ps -ef|grep auto
was 29983 27492 0 16:33 pts/4 00:00:00 /bin/bash prod-auto-restart.sh
was 30003 29983 0 16:33 pts/4 00:00:00 /bin/bash prod-auto-restart.sh
was 30021 27492 0 16:33 pts/4 00:00:00 grep auto
这将叉两个壳,我检查tmp-was-restart.sh,它是正确的,这意味着 命令“sed -i'/ prc_auto_restart/d'tmp-was-restart.sh”执行正确,并且它停在“/wasdata/scripts/systeminf/tmp-was-restart.sh” ,我试着执行source/execute方法,两者都不起作用,在我终止进程29983后,执行了“/wasdata/scripts/systeminf/tmp-was-restart.sh”命令,但是“cat/dev/null>/wasdata/scripts/systeminf/tmp-was-restart.sh“不能执行特德,非常困惑!
任何人都知道放弃这一点? – koko
