I want to read everything from a textfile and echo it. But there might be more lines written to the text-file while I'm reading so I don't want the script to exit when it has reached the end of the file, instead I wan't it to wait forever for more lines. Is this possible in php? ...
I am trying to implement the AudioFileStreamSeek feature on my streaming app. But there is no way I can get this running. Even Matt Gallagher said on his blog: Icidentally, the AudioFileStreamSeek function seems completely broken. If you can't get it to work (as I couldn't) just seek to a new point in the file, set discontinuous to ...
Is there any easy way to tell perl "now ignore everything that is printed"? I have to call a procedure in an external Perl module, but the procedure prints a lot of unnecessary information (all through standard print). I know select can be used to redirect it somehow, but I am not too wise from reading perldoc on it. edit: I found th...

I'm trying to figure out the proper PBP approved way to process a multi line string one line at a time. Many Perl coders suggest treating the multi line string as a filehandle, which works fine unless you have "use strict" in your script. Then you get a warning from the compiler about not being able to use a string as a symbol while st...
In Windows, is there a straightforward way to get the full path of a file, given only the file's handle? I can't use GetFinalPathNameByHandle() because that's Vista+ only and our product has to work on XP. However, something that simple, or close to it, would be best. ...
Does anyone have a solution to the task of processing a multi-line string one line at a time, other than the string-as-a-filehandle solution shown below? my $multiline_string = "line one\nline two\nline three\nline four"; my $filehandle; open( $filehandle, '<', \$multiline_string ) or croak("Can't open multi-line string as a filehan...
I like to use the nifty perl feature where reading from the empty angle operator <> magically gives your program UNIX filter semantics, but I'd like to be able to access this feature through an actual filehandle (or IO::Handle object, or similar), so that I can do things like pass it into subroutines and such. Is there any way to do this...
I'm trying to eject a (virtual) removable drive, and it fails because there are some file handles open, maybe explorer windows. What's the best way to get all the open handles to files on that drive and close them? Is it also feasible (within user-mode) to find any processes running off that drive, so I can warn the user with the proces...
When I issue a Perl script some standard input, e.g. $ awk '{print $1"\t"$2}' foo.txt | myScript.pl I have a script which contains a bug. It reads the first line of standard input, gets something from that first line, and then only parses lines 2 through n of standard input on subsequent read: open (FH, "< $input") or die $?; my $fir...

I quickly jotted off a Perl script that would average a few files with just columns of numbers. It involves reading from an array of filehandles. Here is the script: #!/usr/local/bin/perl use strict; use warnings; use Symbol; die "Usage: $0 file1 [file2 ...]\n" unless scalar(@ARGV); my @fhs; foreach(@ARGV){ my $fh = gensym; ...
Is there any way in Perl to generate file handles programmatically? I want to open ten files simultaneously and write to them by using file handle which consists of (CONST NAME + NUMBER). For example: print const_name4 "data.."; #Then print the datat to file #4 ...
I'm on a server where I'm limited to PHP 5.2.6 which means str_getcsv is not available to me. I'm using, instead fgetcsv which requires "A valid file pointer to a file successfully opened by fopen(), popen(), or fsockopen()." to operate on. My question is this: is there a way to access a string as a file handle? My other option is to ...

If I have a function that might be passed a file name or various file handles or typeglobs, how can the function distinguish among these arguments -- including telling the difference, for example, between *DATA and *STDIN? Updated code, based on answers received so far Thanks, everyone. use strict; use warnings; use FileHandle; sub fi...

I'm copying from a client computer to a server computer in a shared directory. My server detects the new file, and after the copying is complete it has to process it. The problem is that, when writing a big file and using FileSystemWatcher, you get no indication whether the copying is done or not. The only way to check this is by trying ...
