By "database management", do you mean "database administration", as in Oracle DBA?

If that's the case, then Oracle DBA guys usually don't do a lot of programming. And Oracle programmers usually don't do a lot of DBA work.
I say "usually" because there is a select breed of niche "developer DBAs" who can do both. In a large corporation, you may not find opportunities to do both. In smaller companies or startups, such opportunities are more.

Oracle is certified a few *nixes - Oracle Enterprise Linux, Solaris etc. but can run on virtually any Linux distro. If you are doing Oracle DBA work on *nix, then you should:
- know the file and directory structure of the *nix installation
- use commands to navigate around, find files, search/replace in files, zip, rename etc.
- do backup, recovery, using Oracle's utilities etc. on *nix.
- be comfortable with basic shell scripting - usually bash or ksh

If you are an Oracle programmer (who writes SQL, PL/SQL etc.) on *nix, then you should be *very* comfortable with shell scripting, sed, awk and/or scripting languages.

That's because once a SQL script is written, deploying and/or scheduling it in a *nix environment requires a little bit of scripting glue work.
As an example, if you want to connect to Oracle and execute your SQL script for a bunch of dates, spool the results to different files, aggregate the results, mail them to interested parties and then tar gzip the files, version them and move them to an archive directory, then you'd need pretty decent shell scripting skills.

Pick up a good book on Unix or Linux and understand the basics, how the filesystem is structured, what the commands are, how to use them etc.
Learn shell scripting - bash and ksh should be enough for a start.
Learn awk.
Install a Linux system as a VM (or even a dual boot), install Oracle and get comfortable with startup, shutdown, sqlplus etc.
Check this site for posts on Oracle and Linux - there are members here who work on Oracle on Linux. Look at the problems and see how they are solved.

Hope that helps.

NAME

       spell, spellin, spellout - Finds spelling errors

SYNOPSIS

       spell [-b] [-i  | -l] [-v  | -x] [-d hash_list] [-s hash_stop] [-h history_list] [+word_list] [file...]

       spellin [list] [number]

       spellout [-d] list

       The spell command reads words in file and compares them to those in a spelling list.  Default files contain English words only, but you can
       supply your own list of words in other languages.

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       spell:  XCU5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

OPTIONS

       [Tru64 UNIX]  The following options are for the spell command only.  Checks for	correct  British  spelling.   Besides  preferring  centre,
       colour,	programme, speciality, travelled, and so on, this option causes spell to insist upon the use of the infix -ise in words like stan-
       dardise.  [Tru64 UNIX]  Specifies hash_list as the alternate spelling list. The default is /usr/lbin/spell/hlist[ab].  [Tru64 UNIX]  Speci-
       fies  history_list  as the alternate history list that is used to accumulate all output.  The default is /usr/lbin/spell/spellhist.  [Tru64
       UNIX]  Suppresses processing of included files through the and troff macros.  If the -i and -l options are both specified, the last one	of
       the two options entered on the command line takes effect.  [Tru64 UNIX]	Follows the chain of all included files (.so and
