Open/Save

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello my monk friends,

I need to know how to open and save a file.I've looked at getSaveFile and getOpenFile but it just seems to bring up the GUI needed for those operations(and give the name of the file to save or to open). From what I understand I need to create a file and write the data to that file in order to save and to look into the file and read the content in order to open it with our software. Am I way off? Could you give me a guideline of what I would need to use please, it would me much appreciated.

Thanks for your time in advance :o)

perldoc -f open should help you. see also perlopentut. "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]

> getSaveFile and getOpenFile Are these commands in some GUI program? If so, maybe you should mention what program they are in so we'd have some idea of what you are talking about.	[reply]

You can open a file for output as: `open OUT, ">output.txt" or die "Can't open file\n"; print OUT foo close OUT` [download] and you can read as: `open IN, "output" or die "Can't open file\n"; while(<IN>) { # do something with $_ } close IN;` [download] Don't know if this is exactly what you want.

You forgot semicolons after some statements. Anyway, in modern Perl it's written like that: `{ open my $fh, '>', 'filename.ext'; print $fh 'foo'; close $fh; }; { open my $fh, '<', 'filename.ext'; while (<$fh>) { # $_ }; close $fh; };` [download]	[reply] [d/l]
