第四章:grep家族练习题

grep练习:自己做的答案,不是标准答案,应该有更简洁的方法

1.打印所有包含字符串San的行
grep ‘San‘ datebook

2.打印所有名字以J开头的行
grep ‘^J‘ datebook

3.打印所有以700结尾的行
grep ‘700$‘ datebook 

4.打印所有不包含834的行
grep -v ‘834‘ datebook 

5.打印所有生日在十二月的行
grep ‘:12/[0-9]*/[0-9]*:‘ datebook

6.打印所有电话号码区号为408的行
grep ‘[a-z]:408-‘ datebook

7.打印所有包含一个大写字母,后跟4个小写字母,一个逗号,一个空格和一个大写字母的行
grep ‘[A-Z][a-z][a-z][a-z][a-z],[A-Z]‘ datebook

8.打印所有最后一个名字以K或k开始的行
grep ‘^[A-Z][a-z]* [Kk]‘ datebook

9.打印所有薪水为6位数字的行,前导是一个行号
grep  -n ‘[0-9]\{6,\}$‘ datebook

10.打印包含Lincoln或lincoln(不区分大小写的行)
egrep  ‘lincoln|Lincoln‘ datebook 
grep  ‘[lL]incoln‘ datebook

第五章:流编辑器sed练习题

sed练习:自己做的答案,不是标准答案,应该有更简洁的方法
1.把Jon的名字改为Jonathan
sed -n  ‘s/^Jon/Jonathan/p‘ datebook

2.删除头3行
sed ‘1,3d‘ datebook 

3.打印第5~10行
sed -n ‘5,10p‘ datebook
4.删除含有Lane的所有行
sed ‘/Lane/p‘ datebook

5.打印所有生日在十一月或十二月的行
sed -n ‘/[A-Z]\{2,3\} [0-9]*:1[12]/p‘ datebook
6.在以Fred开头的各行末尾加上3颗星
sed  ‘/^Fred/s/$/***/‘ datebook
sed ‘s/^Fred.*[0-9]/&***/‘ datebook

7.将所有包含Jose的行都替换为JOSE HAS RETIRED
sed ‘s/Jose/JOSE HAS RETIRED/g‘ datebook 

8.把Popeye的生日改为11/14/46,假定您不知道Popeye的生日,设法用正则式查找出来
sed -n ‘/\<Popeye\>/s/[0-9]*\/[0-9]*\/[0-9]*/11\/14\/46/p‘ datebook
sed -n ‘\#^Popeye#s#[0-9]*/[0-9]*/[0-9]*#11/14/46#p‘ datebook 

9.删除所有空行
sed ‘/^$/d‘ datebook

10.写一个能完成下列任务的sed脚本
a) 在第一行上方插入标题PERSONNEL FILE
b) 删除以500结尾的工资项
c) 把名和姓的位置颠倒后,打印文件内容
d) 在文件末尾加上THE END

a)解答  1i\PERSONNEL FILE
b)解答  /500$/d                                                 #这个有问题,没有删除500结尾的行
c)解答  s/\(^[^ ]\+\) \([^ :]\+\)/\2 \1/
d)解答 $a\THE END

sed脚本输出结果

sed脚本内容:

#!/usr/bin/sed
1i\PERSONNEL FILE 
/500$/d                                                 #这个有问题,没有删除500结尾的行               
s/\(^[^ ]\+\) \([^ :]\+\)/\2 \1/
$a\THE END

执行sed脚本:sed  -f  sed datebook:

THE END

总结: 不知道为什么/500$/d不能删除以500结尾的行,在vim中查看datebook的行尾符号确实是$符号。工作中grep命令用的比较频繁,sed更多在脚本中用,sed脚本还没有写过。
