-#### Regular expressions
-

-# Simple matching

-if ($x =~ /foo/) { ... }  # true if $x contains "foo"
+# Perl 中，對正規表示式的支援既廣亦深，在 perlrequick、perlretut 等各處文件中
+# 都有更加完整的文件。不過，簡而言之：
 
-# Simple substitution
+# 簡易比對
+if (/foo/)       { ... }  # 若 $_ 內含 "foo" 則為真
+if ($x =~ /foo/) { ... }  # 若 $x 內含 "foo" 則為真

-$x =~ s/foo/bar/g;        # replaces ALL INSTANCES of foo with bar in $x
+# 簡易取代
+$x =~ s/foo/bar/;         # 將 $x 中第一個出現的 foo 換為 bar
+$x =~ s/foo/bar/g;        # 將 $x 中所有出現的 foo 換為 bar
 
+#### 檔案與輸出入
 
-#### Files and I/O
+# 以 "open" 函式開檔後，便可自檔案輸入或對其輸出
 
-# You can open a file for input or output using the "open()" function.
-
-# For reading:
+# 讀檔：
 open(my $in,  "<",  "input.txt")  or die "Can't open input.txt: $!";
-# For writing (clears file if it exists):
+
+# 寫檔（若檔案已經存在，舊內容會被清空）：
 open(my $out, ">",  "output.txt") or die "Can't open output.txt: $!";
-# For writing (appends to end of file):
+
+# 寫檔（若檔案已經存在，會寫到檔尾去）：
 open(my $log, ">>", "my.log")     or die "Can't open my.log: $!";
 
-# You can read from an open filehandle using the "<>" operator.  In
-# scalar context it reads a single line from the filehandle, and in list
-# context it reads the whole file in, assigning each line to an element
-# of the list:
+# 使用 "<>" 算符，能對檔案代號進行讀取。在純量語境下，會自檔案代號讀一列內容。
+# 而在串列語境下，對讀入整個檔案。每一列都會成為串列中一項元素。
