[code］
Symbol        Function
%        Matches the start of line - Indicates the search string must be at the beginning of a line but does not include any line terminator characters in the resulting string selected.
$        Matches the end of line - Indicates the search string must be at the end of line but does not include any line terminator characters in the resulting string selected.
?        Matches any single character except newline
*        Matches any number of occurrences of any character except newline
+        Matches one or more of the preceding character/expression.  At least one occurrence of the character must be found.
++        Matches the preceding character/expression zero or more times.
^b        Matches a page break
^p        Matches a newline (CR/LF) (paragraph) (DOS Files)
^r        Matches a newline (CR Only) (paragraph) (MAC Files)
^n        Matches a newline (LF Only) (paragraph) (UNIX Files)
^t        Matches a tab character
[ ]        Matches any single character, or range in the brackets
^{A^}^{B^}        Matches expression A OR B
^        Overrides the following regular expression character
^(...^)        Brackets or tags an expression to use in the replace command.  A regular expression may have up to 9 tagged expressions, numbered according to their order in the regular expression.The corresponding replacement expression is ^x, for x in the range 1-9.  Example: If ^(h*o^) ^(f*s^) matches "hello folks", ^2 ^1 would replace it with "folks hello".
Note - ^ refers to the character '^' NOT Control Key + value.

不好意思
看错了

1.不知道你要找的是不是正则表达式，偶有一个函数专门用来解决你这个问题的：

# trim space / tab at the end
sub trim {
        my $r = shift;
        $r =~ s/[      \n\r]+$//;
        return $r;
}

2.当然你也可以直接使用函数“chomp”;
3.Sample:

****************************************
use strict;
my $iline;
open(INFILE,"123.txt" ) or die"Open Failed!~";
open(OUTFILE,">456.txt" ) or die"Open Failed!~";
while(<INFILE>; )
{
  $iline=$_;
  $iline=trim($iline) ;
  #chomp $iline;
  print OUTFILE $iline;
}
close OUTFILE;
close INFILE;

# trim space / tab at the end
sub trim {
        my $r = shift;
        $r =~ s/[      \n\r]+$//;
        return $r;
}
***********************************

123.txt的内容你可以随意，
456.txt将是你要看到的结果，
可以自己测试一下，
如果要使用trim就直接使用此sample;
如果要使用chomp就注释掉使用trim函数的代码，并取消chomp的注释；
呵呵，一点浅见，有问题可以直接联系我，QQ:642977474

建议试试 vim

Lonki

UltraEdit有一个选项, 大概是"起用Perl兼容正则式", 太老的版未提供.
这样就不用去记UE的那一套了:>
