  Cat (Unix)
Among Unix fans, cat(1) is considered an excellent example of user-interface design, because it delivers the file contents without such verbosity as spacing or headers between the files, and because it does not require the files to consist of lines of text, but works with any sort of data.
Among Unix haters, cat(1) is considered the canonical example of bad user-interface design, because of its woefully unobvious name.
UUOC [from the comp.unix.shell group on Usenet] stands for `Useless Use of cat'; the reference is to the Unix command cat(1), not the feline animal.

 cat(1)   (Site not responding. Last check: )
DESCRIPTION [Tru64 UNIX] The cat command is frequently used with > (redirection sym- bol) to concatenate the specified files and write them to the specified destination.
To concatenate several files, enter: cat section1.1 section1.2 section1.3 > section1 This creates a file named section1 that is a copy of section1.1 fol- lowed by section1.2 and section1.3.
The result is the same if you do not use the -s option, except that cat displays the error message: cat: cannot open section2.1 You may want to suppress this message with the -s option when you use the cat command in shell procedures.

 Introduction to Shell Scripting - Part 3 LG #113
Strange as it may seem, 'cat' - which you've probably used on innumerable occasions - can do a number of useful things beyond simple concatenation and printing to the screen.
As an example, 'cat -v file.txt' will print the contents of "file.txt" to the screen - and will also show you all the non-text characters that might normally be invisible (this excludes the standard textfile characters such as `end-of-line' and `tab'), in '^' (for Ctrl- characters) and 'M-' (for Alt- characters) notation.
I tend to think of 'cat' as an "initial processor" for text that will be further worked on with other tools.

Historically, and even on some modern embedded devices, thefilesystems either have no support for directories at all or only have a flat directory structure, meaning subdirectories are not allowed; there is only a group of top–level directories each containingfiles.
Strictly speaking, there is a difference between a directory which is a filing system concept, and the WIMP metaphor that is used to represent it (a folder).
Note that the folder metaphor may be misleading with regard to things likefile permissions on UNIX : To rename or delete a file you need write permission to thedirectory that contains the file.

 Linux/Unix Text Processing Tools | Linux Magazine
Now that we've messed around with cat, cut, and grep, let's check out another old-school Unix text-tool -- sed, the so-called "stream editor." Sed is a very complicated and multi-functional tool.
Still, the concept of how sed works is fairly straightforward; generally, it takes an input stream, modifies it by your rules, and creates output.
Tie that together with grep, cut, cat, and redirection and you start to see the power of all these tools.
