One often-overlooked feature of Bourne shell script programming is that you can easily write functions for use within your script. This is generally done in one of two ways; with a simple script, the function is simply declared in the same file as it is called.

Exit codes are a number between 0 and 256, which is returned by any Unix command when it returns control to its parent process. Other numbers can be used, but these are treated modulo 256, so exit -10 is equivalent to exit 246 , and exit 257 is equivalent to exit 1 . These can be used within a shell script to change the flow of execution depending on the success or failure of commands executed.

UNIX Shell Script Tutorials & Reference
The next few sections are all based on the syntax rules for the Bourne shell as listed in the man pages for sh from my system. Compare these rules with those of your system. There may be slight differences where the specification of the sh is loosely defined.
This tutorial assumes no previous knowledge of scripting or programming, but progresses rapidly toward an intermediate/advanced level of instruction . . . all the while sneaking in little nuggets of UNIX ® wisdom and lore . It serves as a textbook, a manual for self-study, and a reference and source of knowledge on shell scripting techniques. The exercises and heavily-commented examples invite active reader participation, under the premise that the only way to really learn scripting is to write scripts .
Advanced Bash-Scripting Guide
Well, most likely because the are a simple way to string together a bunch of UNIX commands for execution at any time without the need for prior compilation. Also because its generally fast to get a script going. Not forgetting the ease with which other scripters can read the code and understand what is happening.
UNIX Shell Script Tutorials & Reference
Oracle acquired Sun in 2010, and since that time Oracle's hardware and software engineers have worked side-by-side to build fully integrated systems and optimized solutions designed to achieve performance levels that are unmatched in the industry. Early examples include the Oracle Exadata Database Machine X2-8 , and the first Oracle Exalogic Elastic Cloud , both introduced in late 2010. During 2011, Oracle introduced the SPARC SuperCluster T4-4 , a general-purpose, engineered system with Oracle Solaris that delivered record-breaking performance on a series of enterprise benchmarks. Oracle's SPARC-based systems are some of the most scalable, reliable, and secure products available today.

+---------------------------------------------------+ |Character Meaning | +---------------------------------------------------+ |b Block special file (see mknode(8)) | |c Character special file (see mknode(8)) | |d Directory | |f Plain file | |p Named Pipe File | |l Symbolic link | |s Socket | +---------------------------------------------------+ It can be difficult to keep track of all of the symbolic links in a directory. The next command will find all of the symbolic links in your home directory, and print the files your symbolic links point to. Find has several options that take a decimal integer. One such argument is -size . The number after this argument is the size of the files in disk blocks.
Examples of Usage of Unix Find Command
Unix File Finding Commands.Find File Shell Script. Search File Unix ...
Following are some bunch of commands that might be useful if you want to find files in unix/linux. There have been instances where a runaway process is seemingly using up any and all space left on a partition. Finding the culprit file is always useful. Better still, if we know a file is being written to now, we can touch a file and ask the find command to list any files updated after the timestamp of that file, which will logically then list the rogue file in question.
Bash While Loop Example
H ow do I use bash while loop to repeat certain task under Linux / UNIX operating system? How do I set infinite loops using while statement? The bash while loop is a control flow statement that allows code or commands to be executed repeatedly based on a given condition.An Introduction to Shell Scripting with bash (continued) In the last article, we dealt with variables and positional parameters. This month, it's time to examine the more advanced features that make scripts much more powerful, especially bash's flow control capabilities. Functions The bash shell allows us to define functions, which are effectively subroutines. This makes complex scripts significantly simpler, as well as making them faster.
An Introduction to Shell Scripting with bash (Part 2)
This article intends to help you to start programming basic-intermediate shell scripts. It does not intend to be an advanced document (see the title). I am NOT an expert nor guru shell programmer. I decided to write this because I'll learn a lot and it might be useful to other people. Any feedback will be apreciated, specially in the patch form :) http://www.linuxdoc.org/HOWTO/Bash-Prog-Intro-HOWTO.html
BASH Programming - Introduction HOW-TO
A word from the author When programmers start to use the Solaris product, they want to begin programming scripts immediately. They're not concerned initially with efficiency and elegance; they're concerned with effectiveness. This article explains my proven shell programming techniques to get started quickly. As you become more experienced, you can develop your own programming style and improve the efficiency and elegance of your scripts.
