Perl reads and writes gz compressed files

Perl input and output files are usually text files, but compressed files can also be processed. Similar to normal file reading and writing, you need to get a file handle, with a slight change.

Enter the file handle:

Open IN, "gzip-dc infile.gz |"

Output file handle:

Open OUT, "| gzip > outfile.gz" or die $!; you can also use package: PerlIO::gzipuse PerlIO::gzip; # Perl IOopen FQ, ": gzip", file2.gz | | die "$!"

Merge gz files

Zcat file1.gz file2.gz | gzip > file3.gz Thank you for reading this article carefully. I hope the article "perl how to read and write gz compressed files" shared by the editor will be helpful to you.
