Linux常用Shell脚本珍藏
(2)编写任务定时器:
C代码☆
1. echo 00 1 *k */bin/sh /usr/bin/fileback">:/root/etcbakcron
2. crontab /root/etcbakcron
3.或使用 crontab-e命令添加定时任务:
4.01** s */bin/sh /usr/bin/ fileback
6.有一普通用户想在每周日凌晨零点零分定期备份/user/ backup到/tmp目录下,该用户应如何做?
参考答案:
(1)第一种方法
代码☆
1.用户应使用 crontab-c命令创建 crontab文件。格式如下
2.00x
cp -r /user/backup /tmp
(2)第二种方
用户先在自己日录下新建文件fil,文件内容如下
C代码☆
1.0 * sun cp -r /user/backup /tmp
然后执行 crontab file使生效。
7.设计一个She11程序,在/ userdata目录下建立50个目录,即user1~user50,并设置每个目录的权限,其中其他用户
的权限为:读;文件所有者的权限为:读、写、执行:;文件所有者所在组的权限为:读、执行
参考答案:建立程序Pro16如下:
C代码☆
1. #! /bin/ sh
3. while[ i -le 50 1
5. if
d / userdata ]:then
6. mkdir -p /userdata/users
7. chmod 751/userdata/uscrSi
8. echo
user
e
(或i-S(($i+1))
10. else
11. mkdir /userdata
12. mkdir - p /userdata/user si
13. chmod 754 /userdata/user$i
14.echo“user$
5.1et“i=j+
(或i=S(($i+1))
16,fi
17. donc
8、 mysql各份实例,自动备份mysq1,并删除30人前的各份文件
C代码☆
1. #!/bin/sh
3. Auto backup mysql
4.#wugk-07-14
5. EPATH DEFINE
7. BAKDIR-/data/ backup, my sql/ datc +%Y-%m-%d
8. MYSQLDB=Www
9. MYSQLPW=backup
10. MYSQLUSR-backup
11
12. if[ SUID -ne 0 1; then
13. echo This script must use administrator or root user please exit
p
15. exit 0
16. fi
17
18. if[! -d SBAKDIR ] then
19. mkdir -p $ BAKDIR
20. else
21. echo This is SBAKDiR exists please exit..
22.sl
eep 2
3. exit
24.f
26. ###mysqldump backup mysql
28. /usr/bin/mysql dump -usMYSQLUSR -pSMYSQLPW-d $MYSQLDB > data/backup/mysql/ date +%Y
d
30
By cd SBAKDIR
tar -czf www mysql db. tar. gz * sql
32. cd $BAKdIR find
name“米.sq1” xargs rm-rf[$?-eq0]&echo“ This date+%Y
Dom-od resin baCKUP is SUCCESS
34. cd /data/backup/ my sql, find.-mtime +30 xargs rm
9、自动安装 nginx脚本,采用ease方式,选择方式,也可以根据实际需求改成自己想要的驸本
C代码☆
1. #!/bin/ sh
3. ###nginx install shell
1.##Wugk-07-11
5. ###PATH DEFINE
7. SOFT PATH-/data/sof
8. NGINX FILE=nginx-1. 2.0. tar gz
9. DowN Path=httP: //nginx. org/download/
11. if[ SUID-ne 0];then
12. echo This script must use administrator or root user please exit
Sleep
14. exit o
15,f
17. if[ -d SSOFT PATH ]; then
8. mkdir -p $SOFT PATH
19.fi
21. download O
23. cd SOFT PATH wget DOWN PATH/ SNGTNX FILE
24.}
26. install O
7.{
8. yum install pcre-devel-y
29. cd SOFT PATH tar xzf NGINX FILE ; cd nginx-1.2.0/&&./configure
3o prefix/usr/local/nginx
Eaewithhttpstubstatus_module-with-http-sslmodule
-eg 0 &&make &&make install
33. start ()
31.
35. Isof
80 S? -ne 0 &&/usr/local/nginx/ sbin/nginx
36.
37
38. stop O
40. ps -ef grep nginx grep-v grep awk [print $2), xargs kill-9
42.
43. exit O
44.{
15. cho s? cxit
46.}
47
48,### case menu###扦
49
50. case sl
1.download
52. download
55. install
56. install
556666666666
59. start
60. start
62. stop
4.;
0
68. echo "USAGE: o download or install or start or stop
9. exit
0. esac
10、批量解压tar脚本,批量解压zip并且建立当前目录。
C代码
1. #!/bin/sh
2. PATHl=/tmp/images
3. PATH2=/usr/www/images
4. for i in s sPATH1)/*
5. do
6. tar xvf S
C $PATH2
7. donc
这个脚本是针对所有tar文件在一个目录,但是实际情况中,有可能在下级或者更深的目求,我们可以使用find查找
代码☆
1. #! /bin/sh
2. PATH1-/ tmp/images
3. PATH2=/usr/www/images
4. for i in find PA
name
”*,tar
567
d
oao
kIf $i-C $PATH2
do
ne
如何是zip文件,例如123189.zip132342.zip等等批量文件,默认 unzip直接解压不带目身目录,意思是解压
123189.zip完当前目录就是图片,不能创建123189目录下并解压,可以用 shell肜本实现
C代码
1. #!/bin/sh
2. PATH1-/tmp/image
3. PATH2=/usr/www/images
4. cd $PATH1
5
6. for i in find
name
iprint
1. do
9. mkdir -p
PATH2Si
11. unzip -o. i zip
PATH2Si
12. done

ssh批量上传文件
上传文件大多数用的是ftp,但是用ftp有一点不好,就是本地和远程的日录要对应,这样就要在多个日录下去切换,这样
挺麻烦的,如果不注意的话,很有可能传错。所以想了个办法利用scp来批量上传文件或者目求
,scp上传不要输入密码
如果要用scp来上传文件,第一步就要去掉scp上传时要输入密码。要不然就没办法批量上传∫。具体请参考:ssh不
用输入密
ssh批量上传脚本
1,要上传的文件列表放到一个tcst文件中
C代码☆
1. root @ubuntu: /home/zhangy# cat test
2./homc/zhangy/tost/aaa
3./homc/zhangy /test/nginx. conf
4
5. /home/zhangy/ test/test. sql
6. /home/zhangy/test/pa. txt
7./home/ zhangy/test/password
上面就要上传约文件。
2,批量上传的脚本
vim file upload. sh
代码☆
1. #!/bin/sh
3 date= date +oy %om od %H
456789
the
for filc in$(scd’/^$/d’$1)
//去掉空行
if[-f file
/普通文件
10
then
res= scp file $2: $file
//上传文件
z res
2345
//上传成功
then
echo file > $(DATE upload log
/上传成功的日志
elif d Sfile 1
//日录
17
then
rcs= scp -r Sfilc $2: $fil
19
z res
20
then
21
echo file > $(DATE) upload log
fi
one
25.el
echono file" > SDATE error log
27.fi
上传成功后,返回的是一个空行,上传不成功,什么都不返回
3,上传的格式
C代码
1.. /file upload. sh test 192. 168 1.13
tcst是上传列表文件,192.168.1.13文件要传到的地方。
