常用shell脚本小工具

摘自，作者：

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-lstart*.sh|awk'{m=$9;gsub（/start/,"stop",$9）;print"cp"m""$9}'

再运行

ls-lstart*.sh|awk'{m=$9;gsub（/start/,"stop",$9）;print"cp"m""$9}'|sh

改名

先查看

ls-lstart*.sh|awk'{m=$9;gsub（/start/,"stop",$9）;print"mv"m""$9}'

再运行

ls-lstart*.sh|awk'{m=$9;gsub（/start/,"stop",$9）;print"mv"m""$9}'|sh

2.改进grep2048字符限制的小工具

我们查找匹配文件时常常遇到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。

forfilein`find.!

-typed`

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：

1.vishowuser建立一个文件,内容只有一句:

find$1-execfuser-u{}\;2>;&1|awk'{if（$2!

=""print$1$2}'

2.chmod755showuser

3.cpshowuser/usr/bin

4.showuser.

showuser/usr

会把当前目录下的在使用的文件的文件名,使用者的id,name显示出来.

4.清理垃圾，可放在crontab里每天执行。

#rmlog.sh

find/tmp!

-name"*.X11*"-mtime+7-execrm-f{}\;

find/var/tmp-mtime+5-execrm-f{}\;

find/var/preserve/recycle-mtime+7-execrm-f{}\;

crontab

01***/home/scripts/rmlog.sh>/tmp/rmlog.log2>&1

5.强制关闭vg（包括umount所有相关文件系统）

#varyoffvg_force.sh

if[$#-le0];then

echo"nopara,example:

varyoff_vg.sherpapp_vg"

exit

fi

df-k|awk'{print$7}'|grep-vMounted>/tmp/fs_mounted.txt

foriin`lsvg-l$1|grep-vE"N/A|vg|MOUNT"|awk'{print$7}'`

do

if[`grep-c$i/tmp/fs_mounted.txt`-ge1];then

echofuser-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[$#-le0];then

echo"nopara,example:

kill_user.sh/applprod"

exit

fi

df-k|awk'{print$7}'|grep-vMounted>/tmp/du_.txt

if[`grep-c$1/tmp/du_.txt`-eq1];then

echofuser-kc$1

fi

7.mklvcopy做镜像

相当于mirrorrootvg，但当rootvg里有不想mirrror的lv或盘大小不一时比较有用。

##mkmirrorvg.sh

mklvcopy-khd52$1

mklvcopy-khd62$1

mklvcopy-khd82$1

mklvcopy-khd42$1

mklvcopy-khd9var2$1

mklvcopy-khd32$1

mklvcopy-khd12$1

mklvcopy-khd22$1

mklvcopy-khd10opt2$1

mklvcopy-klg_dumplv2$1

bosboot-ad$1

bootlist-mnormal$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-vMounted>/tmp/df_mounted.txt

cd/

foriin`ls-l|awk'{print$9}'|grep-v"\-i"`

do

if[`grep-c$i/tmp/df_mounted.txt`-eq0];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-vMounted|grep-vproc|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

errclear0

11.起大量shell脚本

#start_procs.sh

catstart_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

catprocs.list|awk'{print"stop_proc.sh"$1}'|sh

#stop_proc.sh

ps-ef|grep$1|grep-vgrep|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"-----------lslvlv";lsvg-l`lsvg-o`|grep-v"LVNAME"|grep-vawk'{print"lslv"$1}'|sh

echo-----------df;df-k;lsfs

echo-------------netstat;netstat-in;netstat-i;netstat-r

echo-------------------ps;ps-efk;psgu

echo------------------lscfg;lscfg-vp

echo--------------lssrc;lssrc-a

echo------------lsslot;lsslot-cpci

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-------------hostsfile;cat/etc/hosts

if[`ps-ef|grepcluster|grep-vgrep|wc-l`-ge1];then

echo-------------HAINFO

/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

echoforexample:

:

chmod_dir.shrwx/home/mxin/mon

echo$1$2>/tmp/chmod_dir.txt

cat/tmp/chmod_dir.txt|awk-F/'{print"chmodo+x/"$2";chmodo+x/"$2"/"$3";chmodo+x/"$2"/"$3"/"$4";chmodo+x/"$2"/"$3"/"$4"/"$5";chmod-Ro+"$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

echo0>warn_count

fi

warn_count=`catwarn_count`

sqlplus"/assysdba"<

setfeedoff;

cat/tmp/mon_db_lock.out1|grep-vSQL|grep[0-9]|awk'{print"grep\""$0"\"/tmp/mon_db_lock.out2"}'|sh>/tmp/db_lock1

if[`cat/tmp/db_lock1|wc-l`-gt0];then

cat/tmp/mon_db_lock.out2|grep-vSQL|grep[0-9]|awk'{print"grep\""$0"\"/tmp/mon_db_lock.out3"}'|sh>/tmp/db_lock2

if[`cat/tmp/db_lock2|wc-l`-gt0];then

cat/tmp/mon_db_lock.out3|grep-vSQL|grep[0-9]|awk'{print"grep\""$0"\"/tmp/mon_db_lock.out.old"}'|sh>/tmp/db_lock3

if[`cat/tmp/db_lock3|wc-l`-gt0];then

cat/tmp/db_lock3|awk'{print"walldblock-------\""$0"\"!

!

"}'|sh

letwarn_count=$warn_count+1

fi

fi

fi

cp/tmp/mon_db_lock.out3/tmp/mon_db_lock.out.old

if[$warn_count-gt4];then

16.监控oracle的表空间

#mon_ts_space.sh

cd/home/oraprod

sqlplus"/assysdba"<

setfeedoff;

setheadingoff;

spool/tmp/mon_ts_space.out;

@mon_ts_space.sql

exit

EOF

cat/tmp/mon_ts_space.out|grep-vSQL|grep[0-9]|awk-fmon_ts_space.awk

#mon_ts_space.sql

select

df.tablespace_name"Tablespace",

（df.totalspace-fs.freespace）"UsedMB",

fs.freespace"FreeMB",

df.totalspace"TotalMB",

round（100*（fs.freespace/df.totalspace））"Pct.Free"

from

dba_tablespacests,

（selecttablespace_name,

round（sum（bytes）/1048576）TotalSpace

fromdba_data_files

groupbytablespace_name）df,

（selecttablespace_name,

round（sum（bytes）/1048576）FreeSpace

fromdba_free_space

groupbytablespace_name）fs

where

ts.tablespace_name=fs.tablespace_name

and

df.tablespace_name=fs.tablespace_name（+）

and

round（100*（fs.freespace/df.totalspace））<20

anddf.tablespace_namenotin（'APPS_UNDOTS1','TEMP'）;

17.只清除所有当前使用该vg的用户

#kill_vg_user.sh

if[$#-le0];then

echo"nopara,example:

kill_vg_user.sherpapp_vg"

exit

fi

df-k|awk'{print$7}'|grep-vMounted>/tmp/fs_mounted.txt

foriin`lsvg-l$1|grep-vE"N/A|vg|MOUNT"|awk'{print$7}'`

do

if[`grep-c$i/tmp/fs_mounted.txt`-ge1];then

echofuser-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.todayislastdayofthismonth.runit!

"

#insertyourshellscripts

fi

19.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.todayisfirstdayofthismonth.runit!

"

#insertyourshellscripts

fi

20.跟踪oracleexport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`-lt1];then

echo"dbdvlpexportfail!

!

!

"#报警

wall"dbdvlpexportfail!

!

!

"

fi

21.检查系统的进程

a.check_proc.sh:

#check_proc.sh

catcheck_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

exportLANG=en_US

count=`ps-ef|grep"$2"|grep-vgrep|wc-l`

if[$count-lt$3];then

echo$1hasnotbestartedall,thenumberis$count/$3!

fi
