I'll take a look at Files, Hashes, and Input and Output. I'm feeling ambitious.

• Files
• Answer: How do I read the contents of a file? -- needs a return value check and formatting cleanup.
• Answer: How do I append or write to the end of a file? does too.
• Answer: How do I delete a file? needs to check the return value.
• Answer: How do I read an entire file into a string? needs an explanation and a return value check for open.
• Answer: How do you write to the middle of a file? does too. The answer given there isn't as simple as the one posed in the question, either.
• how to use arguments in the code. belongs somewhere else. programs and processes perhaps?
• how do i add file/folder needs an example or two in the answer.
• How do i read and search into a text file which is in another remote host? should go in network programming, perhaps, or just go away. It's an incomplete question.
• How do you store a line from a file in a variable? is the same type of question as How do I read contents of a file?.
• I need an array of filehandles. should be changed to How do I create an array of filehandles? and the two answers combined.
• Is it possible to get a filename from a filehandle? is a FAQ, according to merlyn.
• How do i go to a particular char in a file. How do u use the fseek function? could be renamed "How do I seek a certain position in a file?" Perl doesn't seem to have an fseek function, though C does. It also has a couple of thank you posts.
• Is there a method to extract a certain number of char from a line in a file? could probably go away, as it's a description of substr. Or else, rename it to "How can I extract a certain number of characters from a file?"
• good methods for searching large log files? could be changed to "How can I process large files efficiently?"
• Answer: How do I delete files based on their timestamp? can be deleted, according to BBQ.
• How do I test if a file has write permission? could use a bit of formatting touch-up.
• How do I implement belongs in CGI programming, and should be called "How can I check the HTTP_REFERER variable against a list of referrers?"
• Hashes
• How do I use/reference Multidimensional hashed arrays? confuses me. Is it about an array or a hash or some combination of the two?
• How do I completely remove a key/value pair from my hash? needs a bit of formatting and a # to mark the comment in vroom's answer.
• Why is this statement always evaluating to true? has more to do with true/false values than hashes, and should have been asked in Seekers of Perl Wisdom.
• Input and Output
• Funny usage of print function could be renamed to "Why does Perl print newlines embedded in a string?", but that would make the answer super obvious. :)
• how do i redirect STDOUT, STDIN, or STDERR to a FILE? needs one authoritative answer. Perhaps Buckaroo Buddha could concatenate his responses.
• Bad file description for win32/bash/perl combo should have been in Seekers of Perl Wisdom.
