AIX shell 工具集

时间：2007-04-11 来源：kuber

1.批量改名或拷贝文件
比如将 start*.sh文件改为stop*.sh
拷贝
先查看
ls -l start*.sh|awk '{m=$9; gsub(/start/,"stop",$9);print "cp "m " "$9}'
再运行
ls -l start*.sh|awk '{m=$9; gsub(/start/,"stop",$9);print "cp "m " "$9}'|sh
改名
先查看
ls -l start*.sh|awk '{m=$9; gsub(/start/,"stop",$9);print "mv "m " "$9}'
再运行
ls -l start*.sh|awk '{m=$9; gsub(/start/,"stop",$9);print "mv "m " "$9}'|sh

for i in `echo start*.sh`
do
cp $i `echo $i|sed 's/start/stop/g'` #拷贝
#mv $i `echo $i|sed 's/start/stop/g'` #改名
done

2.改进grep 2048字符限制的小工具
我们查找匹配文件市常常遇到grep报行长度超过2048这样的错误，我做了这个小工具，findtxt,可查找当前目录下的匹配文件，如果需要，把注释打开，可显示匹配内容。希望对大家有所帮助。

for file in `find . ! -type d`
do
line=`sed -n /$1/p $file`
if [ "$line" != "" ]; then
echo $file
# echo $line
  fi
done
3.查看文件使用者的小工具
对fuser的一点改进,呵呵.
1.vi showuser  建立一个文件,内容只有一句:
find $1  -exec fuser -u {} \; 2>;&1|awk '{ if ($2 != ""  print $1 $2 }'
2. chmod 755 showuser
3. cp showuser /usr/bin
4.  showuser  .
   showuser  /usr
4.清理垃圾，可放在crontab里每天执行
#rmlog.sh
find /tmp ! -name "*.X11*" -mtime +7 -exec rm -f {} \;
find /var/tmp -mtime +5 -exec rm -f {} \;
find /var/preserve  /recycle -mtime +7 -exec rm -f {} \;
crontab
0 1 * * * /home/scripts/rmlog.sh  > /tmp/rmlog.log 2>&1 5.强制关闭vg（包括umount所有相关文件系统）
#varyoffvg_force.sh
if [ $# -le 0  ]  ;then
echo "no para, example:varyoff_vg.sh erpapp_vg "
exit
fi
df -k|awk '{print $7 }'|grep -v Mounted >/tmp/fs_mounted.txt
for i in `lsvg -l $1 |grep -vE "N/A|vg|MOUNT"|awk '{print $7}'`
do
if [ `grep -c $i /tmp/fs_mounted.txt`  -ge 1 ] ; then
  echo fuser -kc $i
  umount $i
fi
done
varyoffvg $1

6.kill_fs_user.sh (停掉使用某文件系统的用户，自动判断该文件系统是否mount，避免kill掉其他用户）
if [ $# -le 0  ]  ;then
echo "no para, example:kill_user.sh /applprod "
exit
fi
df -k|awk '{print $7 }'|grep -v Mounted >/tmp/du_.txt
if [ `grep -c $1  /tmp/du_.txt`  -eq 1 ] ; then
  echo fuser -kc $1
fi

7.相当于mirror rootvg，但当rootvg里有不想mirrror的lv或盘大小不一时比较有用。
##mkmirrorvg.sh
mklvcopy -k hd5 2 $1
mklvcopy -k hd6 2 $1
mklvcopy -k hd8  2 $1
mklvcopy -k hd4  2 $1
mklvcopy -k hd9var  2 $1
mklvcopy -k hd3 2 $1
mklvcopy -k hd1 2 $1
mklvcopy -k hd2 2 $1
mklvcopy -k hd10opt  2 $1
mklvcopy -k lg_dumplv  2 $1
bosboot -ad $1
bootlist -m normal $1

8. 察看根目录各文件和子目录大小，去除文件系统统计
# du_.sh

df -k|awk '{print $7 }'|grep -v Mounted >/tmp/df_mounted.txt
cd /
for i in `ls -l|awk '{print $9}'|grep -v "\-i"`
do
if [ `grep -c $i /tmp/df_mounted.txt` -eq 0 ] ; then
du -sk $i
fi
done

9.防止文件系统下和根目录下rm -rf * 误操作。
#deny_rmall.sh
cd /;touch ./-i;df -k|grep -v Mounted|grep -v proc|grep -v "\/tmp"|awk '{print "cp \"./-i\" " $7'}|sh
cp "/-i" /etc
cp "/-i" /dev

10. 保存清理errpt，（当然可以改为其他目录）
#errclear.sh
errpt >/home/mxin/mon/log/errpt_`date +%Y%m%d`.log
errpt -a >>/home/mxin/mon/log/errpt_`date +%Y%m%d`.log
errclear 0

11.起大量shell脚本
#start_procs.sh
cat start_procs.list|awk '{print "sh "$1".sh"}'|sh

#start_procs.list(可追加修改)
startprocessor
ProcProcessor
/home/scripts/startArocessor
p_mj_deal_cardevent

12.停大量进程
# stop_procs.sh
cat procs.list|awk '{print "stop_proc.sh "$1}'|sh

#stop_proc.sh
ps -ef|grep $1|grep -v grep|awk '{print "kill -9 "$2}'|sh

#stop_procs.list(可追加修改)
startprocessor
ProcProcessor
Jackrocessor
p_mj_deal_cardevent

13.收集系统信息
echo --------------------------------------`hostname`-------------------------------------------
prtconf
echo -----------lsvg;lsvg `lsvg -o`
echo "-----------lsvg -l ";lsvg -l `lsvg -o`
echo "-----------lslv lv ";lsvg -l `lsvg -o`|grep -v "LV NAME"|grep -v |awk '{print "lslv "$1}'|sh
echo -----------df;df -k;lsfs
echo -------------netstat;netstat -in;netstat -i;netstat -r
echo -------------------ps;ps -efk;ps gu
echo ------------------lscfg;lscfg -vp
echo --------------lssrc;lssrc -a
echo ------------lsslot;lsslot -c pci
echo -------------lspv;lspv
echo -------------lslpp;lslpp -l
echo -------------lsattr; lsdev -C|awk '{print "echo ---"$1";lsattr -El " $1}'|sh
echo -------------prtconf -v;prtconf -v
echo -------------errpt; errpt ;errpt -a
echo -------------major; ls -al /dev/*
echo -------------hosts file; cat /etc/hosts
if [ `ps -ef|grep cluster|grep -v grep|wc -l` -ge 1 ] ;then
echo -------------HA INFO
/usr/es/sbin/cluster/utilities/cltopinfo -c;/usr/es/sbin/cluster/utilities/cltopinfo -n;/usr/es/sbin/cluster/utilities/clshowres -n
`hostname`;/usr/es/sbin/cluster/utilities/cldisp
fi

14.将多级子目录的权限放开
#chmod_dir.sh
echo for example::chmod_dir.sh rwx /home/mxin/mon
echo $1$2 >/tmp/chmod_dir.txt
cat /tmp/chmod_dir.txt|awk -F / '{print "chmod o+x /"$2";chmod o+x /"$2"/"$3";chmod o+x /"$2"/"$3"/"$4";chmod o+x /"$2"/"$3"/"$4"/"$5";chmod -R o+"$1" /"$2"/"$3"/"$4"/"$5"/"$6}'|sh

15.监控oracle是否有锁
#mon_db_lock.sh
. .profile
cd  /home/mxin/mon
if [ `date +%H%M` = "0800" ]; then
echo 0 > warn_count
fi
warn_count=`cat warn_count`
sqlplus "/as sysdba" <<EOF
set feed off;
set heading off;
spool /tmp/db_lock.out1;
@mon_db_lock.sql
spool off;
exit
EOF
sleep 13
sqlplus "/as sysdba" <<EOF
set feed off;
set heading off;
spool /tmp/db_lock.out2;
@mon_db_lock.sql
spool off;
exit
EOF
sleep 27
sqlplus "/as sysdba" <<EOF
set feed off;
set heading off;
spool /tmp/db_lock.out3;
@mon_db_lock.sql
spool off;
exit
EOF
cat  /tmp/db_lock.out1|grep -v SQL|grep [0-9] >/tmp/mon_db_lock.out1
cat  /tmp/db_lock.out2|grep -v SQL|grep [0-9] >/tmp/mon_db_lock.out2
cat  /tmp/db_lock.out3|grep -v SQL|grep [0-9] >/tmp/mon_db_lock.out3
cat /tmp/mon_db_lock.out1|grep -v SQL|grep [0-9]|awk '{print "grep \""$0"\" /tmp/mon_db_lock.out2"}'|sh >/tmp/db_lock1
if [ `cat /tmp/db_lock1|wc -l` -gt 0 ] ; then
  cat /tmp/mon_db_lock.out2|grep -v SQL|grep [0-9]|awk '{print "grep \""$0"\" /tmp/mon_db_lock.out3"}'|sh >/tmp/db_lock2
  if [ `cat /tmp/db_lock2|wc -l` -gt 0 ] ; then
cat /tmp/mon_db_lock.out3|grep -v SQL|grep [0-9]|awk '{print "grep \""$0"\" /tmp/mon_db_lock.out.old"}'|sh >/tmp/db_lock3
if [ `cat /tmp/db_lock3|wc -l` -gt 0 ] ; then
cat /tmp/db_lock3|awk '{print "wall  db lock-------\" "$0 "\"!!" }'|sh
let warn_count=$warn_count+1
fi
  fi
fi
cp /tmp/mon_db_lock.out3 /tmp/mon_db_lock.out.old
if [ $warn_count -gt 4 ] ; then
  beep.sh
  echo 0 > warn_count
fi

#mon_db_lock.sql

WHERE a.object_id = b.object_id and a.session_id=c.sid
/

16.监控oracle的表空间
# mon_ts_space.sh
cd  /home/oraprod
sqlplus "/as sysdba" <<EOF
set feed off;
set heading off;
spool /tmp/mon_ts_space.out;
@mon_ts_space.sql
exit
EOF
cat  /tmp/mon_ts_space.out|grep -v SQL|grep [0-9]|awk -f mon_ts_space.awk

# mon_ts_space.sql
select
df.tablespace_name                         "Tablespace",
(df.totalspace - fs.freespace)             "Used MB",
fs.freespace                               "Free MB",
df.totalspace                            "Total MB",
round(100 * (fs.freespace / df.totalspace)) "Pct. Free"
from
dba_tablespaces                            ts,
(select tablespace_name,
      round(sum(bytes) / 1048576) TotalSpace
   from dba_data_files
   group by tablespace_name)                df,
(select tablespace_name,
      round(sum(bytes) / 1048576) FreeSpace
   from dba_free_space
   group by tablespace_name)                fs
where
ts.tablespace_name = fs.tablespace_name
and
df.tablespace_name = fs.tablespace_name(+)
and
round(100 * (fs.freespace / df.totalspace)) <20
and df.tablespace_name not in ('APPS_UNDOTS1','TEMP');

17.只清除所有当前使用该vg的用户
#kill_vg_user.sh
if [ $# -le 0  ]  ;then
echo "no para, example:kill_vg_user.sh erpapp_vg "
exit
fi
df -k|awk '{print $7 }'|grep -v Mounted >/tmp/fs_mounted.txt
for i in `lsvg -l $1 |grep -vE "N/A|vg|MOUNT"|awk '{print $7}'`
do
if [ `grep -c $i /tmp/fs_mounted.txt`  -ge 1 ] ; then
  echo fuser -kc $i
fuser -kc $i
fi
done

18.每月月底执行的脚本
#month_lastday.sh
. .profile
TZ=TZ-24
echo `date +%d`
if [ `date +%d` = "01" ]; then
echo "ok. today is last day of this month. run it!"
#insert your shell scripts
fi

每月1日执行的脚本
#month_firstdy.sh
. .profile
TZ=TZ+24
echo `date +%d`
if [ `date +%d` = "02" ]; then
echo "ok. today is firstday of this month. run it!"
#insert your shell scripts
fi

19.跟踪oracle export结果的脚本(放在exp脚本最后）
#exp_check.sh
if [ `tail /tmp/exp_dvlp.log|grep " success"|wc -l` -lt 1 ];then
echo "db dvlp export fail!!!" #报警
wall "db dvlp export fail!!!"
fi

20.检查系统的进程
a.check_proc.sh:

#check_proc.sh
cat check_proc.list|awk -F "," {'print "Check_proc.sh  "$1" \""$2"\"" " "$3 '}|sh

b.check_proc.list:（可修改）

telnet,telnetd -a,2
xcom,xcommanager.py,1

c.Check_proc.sh:

#Check_proc.sh
export LANG=en_US
count=`ps -ef|grep "$2"|grep -v grep|wc -l`
if [ $count -lt $3 ];then
echo $1 has  not be started all,the number is $count/$3!
fi
