Upgrading from RHEL5x to RHEL 7x

Hi,

We are upgrading from RHEL 5.x to RHEL 7x.

uuencode --version
uuencode (GNU sharutils) 4.13.3
Copyright (C) 1994-2013 Free Software Foundation, Inc., all rights reserved.

The issue is we have many places where we have used uuencode for attachments and send mail.

Now even after we installed uuencode from shareutils , the same command is not working in RHEL 7 linux.


We get attachment as Junk Characters in the Email body for any attachment we send. This is happening with mail command used like below.

$ uuencode Attachement_file.pdf  Attachements.pdf |mail -s "This is Attachment Mail" [email protected]<mailto:[email protected]>


Can some one let me know what is this issue and how to resolve this.

Thanks
Prasad
