grep,sed,awk命令实例大练习[整理] - 第2页

**wayne** · 03-02-13, 11:53

针对下面的文件内容：
09:58:36.03 2 IMAP-27587 '1001' connected from
09:58:37.58 2 IMAP-27587 '1001' disconnected
09:58:42.84 2 POP-55513 'lujian' connected from

我要显示包含“POP”和"connected from"的行，怎么用grep命令？

**doooom** · 03-02-13, 11:55

grep两次，用pipe

**KornLee** · 03-02-13, 14:08

ykwj121兄,能不能用sed命令实现"显示文件内容,把姓和名颠倒"这个问题呢? 你用了多个cut命令,固然可以完成,但是题目的用意是用sed来实现,恕小弟愚昧

**ykwj121** · 03-02-13, 14:20

呵呵，偶暂时没招了:o
你有什么可以赐教的吗？

**KornLee** · 03-02-13, 14:29

我也没作出来呢:( sed的命令集很多,我觉得是不是用r/w/x/h命令是不是可以呢?
不过兄弟你的思路不错,谢谢~ 让我们努力吧

**artou** · 03-02-13, 14:34

第10题可以这样：
#!/bin/sh
awk 'BEGIN {print "PERSONNEL FILE\n"} {print $0}' datafile > datafile1
sed '/500$/d' datafile1 > datafile2
sed -e 's/[:::]/ /' datafile2 > datafile1
awk '{print $2,$1,$3,$4,$5,$6,$7}' datafile1 > datafile2
awk 'END {print "THE END"} {print $0}' datafile2 > datafile1

**ykwj121** · 03-02-13, 15:12

sed '/500$/d' datafile1 > datafile2
这一行删除了以500结尾的行，而不是工资吧。
题目说“删除以500结尾的工资”，应该是把工资这个数删掉吧。
呵呵，我也不知道我理解的是不是对

**artou** · 03-02-13, 16:19

删除工资可以这样：

sed -e 's/[0-9]\{2,3\}500$//' datafile

**ykwj121** · 03-02-13, 16:32

en，这个可以的。不过只能删除500前面有2个或者3个数字的，不妥，万一有多一位或者少一位的，就不对了。

BTW：我不是故意坑你哦，我只是觉得这样追究可以让大家学到更多东西，你不介意我老这样钻空子吧？

**artou** · 03-02-13, 16:38

那也简单这样就行了吧：

sed -e 's/[0-9]\{1,9\}500$//' datafile

呵呵，只要能学到东西，钻空子又何妨。。。

**ykwj121** · 03-02-13, 16:48

那偶就放心了。
你有没有考虑不用临时文件，把你的第十题用一句来实现？

**artou** · 03-02-13, 17:56

用一句语句实现：

sed -e 's/[0-9]\{1,9\}500$//' datafile | sed -e 's/[:::]/ /' | awk '{print $2,$1,$3,$4,$5,$6,$7,$8,$9}'| awk 'BEGIN {print "PERSONNEL FILE\n"} {print $0}' | awk 'END {print "THE END"} {print $0}'

10.写一个脚本,将:

ykwj121 注册会员注册日期: Jul 2002 帖子: 72 精华: 1	sed '/500$/d' datafile1 > datafile2 这一行删除了以500结尾的行，而不是工资吧。题目说“删除以500结尾的工资”，应该是把工资这个数删掉吧。呵呵，我也不知道我理解的是不是对

ykwj121 注册会员注册日期: Jul 2002 帖子: 72 精华: 1	en，这个可以的。不过只能删除500前面有2个或者3个数字的，不妥，万一有多一位或者少一位的，就不对了。 BTW：我不是故意坑你哦，我只是觉得这样追究可以让大家学到更多东西，你不介意我老这样钻空子吧？

artou 注册会员注册日期: Jan 2003 帖子: 30 精华: 0	那也简单这样就行了吧： sed -e 's/[0-9]\{1,9\}500$//' datafile 呵呵，只要能学到东西，钻空子又何妨。。。

ykwj121 注册会员注册日期: Jul 2002 帖子: 72 精华: 1	那偶就放心了。你有没有考虑不用临时文件，把你的第十题用一句来实现？

artou 注册会员注册日期: Jan 2003 帖子: 30 精华: 0	用一句语句实现： sed -e 's/[0-9]\{1,9\}500$//' datafile \| sed -e 's/[:::]/ /' \| awk '{print $2,$1,$3,$4,$5,$6,$7,$8,$9}'\| awk 'BEGIN {print "PERSONNEL FILE\n"} {print $0}' \| awk 'END {print "THE END"} {print $0}'
