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;

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

if[`cat/tmp/db_lock3|wc-l`-gt0];then
cat/tmp/db_lock3|awk'{print"walldblock-------\""$0"\"!
!
"}'|sh
letwarn_count=$warn_count+1
fi

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

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
