如何出現在文本

Question

例如

第一+後插入在Perl換行符

*aabc aacb aavg +gf avb avb abf 

應該

*aabc aacb aavg 
+gf avb avb abf 

感謝

Answer 1

使用替代：

my $text = '*aabc aacb aavg +gf avb avb abf'; 
$text =~ s/\+/\n+/; 
print $text; 

+ mu st be backslashed to lose its special meaning，\n是換行符。

Answer 2

my $str = "*aabc aacb aavg +gf avb avb abf"; 
$str =~ s/\+/\n\+/; 
print $str; 

Answer 3

> echo "abcd +gkj +bcd" | perl -pe 's/\+/\n\+/' 
abcd 
+gkj +bcd
