I've had a Linux system at home, as well as a Solaris system at home. My wife bought me Sun SPARCStation at a company salvage sale for $300 with a CD-ROM, tape drive, and monitor; I bought a SCSI enclosure and added a few more SCSI drives. That Sun system ran for a few years before the monitor died, and later one of the SCSI drives failed. Later, one of the drives in the Linux system started screeching; that was a salvage machine.
I want to keep my UNIX skills up to date. I used UNIX at work long before I started with Windows.
Work is a Windows shop; I installed Cygwin on my system and used awk to migrate user login data from an Active Directory ldif file to convert a system to a vendor cloud system.
