The unix job market is quite different to the windows one in that qualifications are usually treated as a positive point but the actual subject of the qualification is largly irrelevant - it's more of an indication you can study and learn. The windows makret is generally interested in seeing a list of certifications and quals to get your foot in the door.
Unfortunately, this means that it's quite difficult to get into an interview for a good unix job. As well as knowing your stuff, you need to find the opportunity to show it. Without getting lucky or knowing someone, you might well have to work your way up from a lowly sys-admin or operator.
The job markets that put more weight on certs are easier (for those that have the certs) to get to the interview stage where they can sell themselves.
Skills that are sought after in a unix engineer that might help get you onto the interview list:
- Experiance: Ok so that's not going to be much of an option for you but try to get some part time work (even free work) to give you exposure to unix in the 'real world'.
- Understanding that Unix isn't DOS and Linux is not identical to all other Unix'es.
- Hardware: Do you want to get into this? If so, start learning what's what and the various platforms and their architecture. You don't have to know the latest stuff but being in a position to appreciate how something new works will be very vaulable to employers.
- System V vs BSD vs The hybrids - understanding the differences - try and get some time on several different unix's. Irix, Solaris, Digital Unix (AKA Tru64), AIX and HPUX would be a good start.
- A solid understanding of server security: Get the hang of the basic concepts of security under unix - both at the network level and at the filesystem level. Learn how to user the multi-user nature of unix to seperate all the different subsystems from each other to minimise the damage of a security breach.
- Knowing the commands is nice but knowing a wide range of ways to find the syntax for a new or unknown command quickly is better.
- The phrase "No, I'm not familiar with that one but I'm keen to learn about it!"
- Documentaion - Most engineers are crap at it, try not to be like most engineers

NAME
term::ansi::ctrl::unix - Control operations and queries
SYNOPSIS
package require Tcl 8.4
package require term::ansi::ctrl::unix ?0.1.1?
::term::ansi::ctrl::unix::import ?ns? ?arg...?
::term::ansi::ctrl::unix::raw
::term::ansi::ctrl::unix::raw
::term::ansi::ctrl::unix::columns
::term::ansi::ctrl::unix::rows
_________________________________________________________________
DESCRIPTION
WARNING: This package is unix-specific and depends on the availability of two unix system commands for terminal control, i.e. stty and
tput, both of which have to be found in the $PATH. If any of these two commands is missing the loading of the package will fail.
The package provides commands to switch the standard input of the current process between raw and cooked input modes, and to query the size
of terminals, i.e. the available number of columns and lines.
API
INTROSPECTION
::term::ansi::ctrl::unix::import ?ns? ?arg...?
This command imports some or all attribute commands into the namespace ns. This is by default the namespace ctrl. Note that this is
relative namespace name, placing the imported command into a child of the current namespace. By default all commands are imported,
this can howver be restricted by listing the names of the wanted commands after the namespace argument.
OPERATIONS
::term::ansi::ctrl::unix::raw
This command switches the standard input of the current process to raw input mode. This means that from then on all characters typed
by the user are immediately reported to the application instead of waiting in the OS buffer until the Enter/Return key is received.
::term::ansi::ctrl::unix::raw
This command switches the standard input of the current process to cooked input mode. This means that from then on all characters
typed by the user are kept in OS buffers for editing until the Enter/Return key is received.
::term::ansi::ctrl::unix::columns
This command queries the terminal connected to the standard input for the number of columns available for display.
::term::ansi::ctrl::unix::rows
This command queries the terminal connected to the standard input for the number of rows (aka lines) available for display.
