Using Shell Script in place of Perl script to Unzip the zip files.
Hi Expert,

We have some shell scripts which Internally uses Perl Script to Unzip the source zip files which comes to inbound directory. So now our requirement is to avoid the dependency on Perl Script and us Shell Script to unzip the files. I have the Perl script with me attached can some one help in writing the Shell Script for this which should unzip the files from inbound directory.
I an new to Shell Scripting so some one plese help me on this.
I have attached the Perl script punzip.pl and the Shell script which internally calls the this perl script and unzips. the files.

Any help is highly appreciated.

Regards,
Naveen

To zip a file use command gzip filename

This will create filename.gz

To unzip the same file use gunzip filename.gz

This should help you kick start conversion process of perl to shell script.

from the man pages:
Quote:
Files created by zip can be uncompressed by gzip only if they have a single member com-
pressed with the 'deflation' method. This feature is only intended to help conversion of
tar.zip files to the tar.gz format. To extract a zip file with a single member, use a
command like gunzip <foo.zip or gunzip -S .zip foo.zip. To extract zip files with several
members, use unzip instead of gunzip.
