Re^9: Reading zipped files (.gz)

Sorry, that's my error. The command to open must be:

my $cmd = sprintf 'gzip -cd "%s" |', $file;
[download]

I think now is a good time to (re)read and understand the documentation for open.

Is this method is better or using a module is better??? If there is any change in execution time I dont have any objection. My main concern is memory.	[reply]

Using this method, your program will read line-by-line from what the `gzip` program outputs. Maybe you can measure the differences in RAM usage if you decompress data yourself and if you let `gzip` decompress data.	[reply] [d/l] [select]

It will read all my file into memory. But I think it's not best practice because am dealing with a bit large files. Is there any other way????	[reply]

No, you are wrong. The above will not read all your file into memory.	[reply]
