Basic UNIX Command (part I)

UNIX is an operating system developed by AT&T Bell LABS in 1969. Today the term Unix is used to describe any operating system that conforms to Unix standards, meaning the core operating system operates the same as the original Unix operating system. During the late 1970s and early 1980s, the influence of Unix in academic circles led to large-scale adoption of Unix (particularly of the BSD variant, originating from the University of California, Berkeley) by commercial startups, the most notable of which are Solaris, HP-UX and AIX.

And I think, in order to mastering the SUN Solaris OS, we definitely need to know some of the very basic UNIX commands :D

First thing to remember: UNIX is case-sensitive.
COMMAND and command are not the same
FILES

ls	lists your files
ls -l	lists your files in 'long format', which contains lots of useful information, e.g. the exact size of the file, who owns the file and who has the right to look at it, and when it was last modified
ls -a	lists all files, including the ones whose filenames begin in a dot, which you do not always want to see
more filename	shows the first part of a file, just as much as will fit on one screen
emacs filename	is an editor that lets you create and edit a file
mv filename1 filename2	moves a file
cp filename1 filename2	copies a file
rm filename	removes a file. It is wise to use the option rm -i, which will ask you for confirmation
diff filename1 filename2	compares files, and shows where they differ
wc filename	tells you how many lines, words, and characters there are in a file
chmod options filename	change the read, write, and execute permissions on your files
gzip filename	compresses files
gunzip filename	uncompresses files compressed by gzip
gzcat filename	lets you look at a gzipped file without actually having to gunzip it
lpr filename	print
lpq	check out the printer queue
lprm jobnumber	remove something from the printer queue
genscript	converts plain text files into postscript for printing
dvips filename	print .dvi files
