① 如何利用perl命令行， 來執行正則表達式，尋找匹配的行
樓上的是找出其中之一呀，樓主要的是同時包含兩個句子。
可以這樣
perl -n -e 'print if ($_ =~/Barney/ && $_ =~ /Fred/)' test.txt >new.txt
其實這樣的實現用awk命令這些很好用。樓主可以學習學習awk sed grep 等命令。
我補充個實例吧。
awk '{if (/Barney/ && /Fred/) print }' test.txt > new.txt
more test.txt | grep Barney | grep Fred >new.txt (這個管道用著很有意思)
都測試了一下，可行
② perl: 如下命令
用雙引號：
perl -p -i.bak -w -e "s/a/b/g" fred.pl
---------------------------
C:\Documents and Settings\t>perl -p -e "" fred.pl
abc
C:\Documents and Settings\t>perl -p -i.bak -w -e 's/a/b/g' fred.pl
Useless use of a constant in void context at -e line 1.
C:\Documents and Settings\t>del fred.pl.bak
C:\Documents and Settings\t>perl -p -i.bak -w -e "s/a/b/g" fred.pl
C:\Documents and Settings\t>perl -p -e "" fred.pl

④ aix 腳本 建資料庫,表
在AIX下可用perl腳本可以連接資料庫並進行操作,具體看你是什麼資料庫，到時連接時申明一下
⑤ AIX下如何去除shell腳本中的^M符號
1、dos格式文件傳輸到unix系統時,會在每行的結尾多一個^M,可以將dos文件轉換為unix文件格式。也有可能看不到
2、vi轉換
用命令:set ff?可以看到dos或unix的字樣.vi dos.txt
:set fileformat=unix
:w
3、也可以用sed 這樣的工具來做:
sed 『s/^M//』 filename > tmp_filename
其中^M是同時Ctrl+V+M按出來的，表示回車。
4、或用vi替換
vi dos_file.txt
:%s/^M//g
5、使用tr
命令：tr -d 「\015」 dos_file.txt
6、使用perl
cat dos_file.txt | perl -pe 『~s/\r//g』 > unix_file.txt
⑥ 請教：aix下如何安裝perl環境
開源的gcc自然可以算是最佳選擇。在64位平台的AIX中，如果選擇運用 gcc來編譯perl源代碼，默認情況下是編譯成32位的版本。這樣在編譯DBD::Oracle的時候也須要選擇正確的32位庫，否則不能編譯成功。
⑦ 請問，在AIX中svmon -Pt30 | perl -e 'while(<>){print if($.==2||$&&&!$s++);$.=0 if(/^-+$/)}'這段命令
AIX什麼的我不太懂~
不過後面的perl 命令我可以解釋下
首先需要知道perl 中 $. 的用法，上次閱讀的文件的當前輸入行號，可以簡單的理解為文件的行號，從1開始。
$.=0 if(/^-+$/); 這里的意思就是如果發現本行是以 - 組成的，那麼把當前行號至為0 ，那麼下一行就為1；
print if($.==2||$&&&!$s++); 當這個行號為2的時候（$.==2）或者第一次匹配到-------之後的下一行（$& && !$s++），列印出本行
例如，通道內容如下：
虛擬行號 實際行號 內容
1 1 test line 1
2 2 test line 2 #列印，虛擬行號為2
3 3 test line 3
4 4 ------------------------------------

感覺是個很詭異的邏輯，不知道實際上有什麼用~
⑧ 如何使用perl命令行對文件中插入1行文字
在某文件末尾插入一行文字perl -e 'print "hello"' >> world.txt
⑨ 如何用perl運行單行命令
可以使用單撇號，例如：
$str=`ls-f`;
這個語句執行命令ls -f並把結果存放到字元串變數$str裡面。
⑩ 如何查看AIX系統上次密碼修改時間
在系統文件/etc/security/passwd中記錄有每個用戶登陸密碼的加密形式，以及上次修改密碼的時間，我們以root為例：
root:
password = hVvR/QGnSNKlE
flags =
lastupdate = 1200982154
此處，lastupdate為上次密碼修改時間，以epoch time表示。Epoch time是從Epoch（新紀元時間，傳說中的標志Unix時代開端的那個拂曉)開始計算起，單位為秒，Epoch則是指定為1970年一月一日凌晨零點零分零秒，格林威治時間。我們可以通過下面的命令來轉換epoch time：
#perl -le 'print scalar localtime 1200982154'
Tue Jan 22 06:09:14 2008
所以，root用戶上次修改密碼是在2008年1月22日上午06:09:14。
