Synopsis
The bash shell is a complete programming language, notmerely a glue to combine external Linux commands. Bytaking full advantage of shell internals, shell programscan perform as snappily as utilities written in C orother compiled languages. And you will see how, withoutassuming Unix lore, you can write professional bash 4.0programs ......, Introduction Although most users think of the shell as an interactive command interpreter, it is really a programming language in which each statement runs a command. Because it must satisfy both the interactive and programming aspects of command execution, it is a strange language, shaped as much by history as by design. Brian Kernighan and Rob Pike, The UNIX Programming Environment, Prentice-Hall, 1984 The shell is a programming language. Don't let anyone tell you otherwise. The shell is not just glue that sticks bits together. The shell is a lot more than a tool that runs other tools. The shell is a complete programming language! When a Linux user asked me about membership databases, I asked him what he really needed. He wanted to store names and addresses for a couple of hundred members and print mailing labels for each of them. I recommended using a text editor to store the information in a text file, and I provided a shell script to create the labels in PostScript. (The script, ps-labels, appeared in my first book, Shell Scripting Recipes: A Problem-Solution Approach. ) When the SWEN worm was dumping hundreds of megabytes of junk into my mailbox every few minutes, I wrote a shell script to filter them out on the mail server and download the remaining mail to my home computer. That script has been doing its job for several years., Introduction Although most users think of the shell as an interactive command interpreter, it is really a programming language in which each statement runs a command.

    I like these tomatoes. They are of top quality, without skins and very few seeds. The shipping condition was great, tightly packed in one box. Great value for the price. They appear as shown in the seller's photographs. Great seller. Shipped from the west coast very quickly. Thanks!!!

    Seller does not provide item descriptions, so no idea what you might receive. Prior owner had laminated the covers on this book, which was not mentioned. Might want to write "DO NOT BEND" on your envelopes, as USPS folded the book in half to fit it inside a PO Box. Turn-and-burn book businesses do not add extra seconds to the listing process or take extra precautions against damage. Great price, though.
