That file is called shell script language. Like other programming languages it has variables and flow control statements (e.g. If-then-else, while, for, goto). In Unix there are several shells that can be used, the C shell (csh and its extension, the T C shell tcsh), the.

Globe valves. Typically used for cooling water systems, transporting fuel oil and turbine lube oil systems, a globe valve is a linear motion valve used to stop, start and regulate flow. Conventionally used for isolation and throttling services, the globe has become the world's most common types of valves. In most student and mid-line horns, when a valve oil evaporates so that less than 40% of the original oil remains on the valves, they will begin to hesitate in an unpredictable fashion. In more expensive horns with clean and very tight valves, the slowdown is much sooner and sudden seizing of a valve is common. Valve oil is a water based lubricant, so it won't hurt your instrument, but using oil or silicone based lubricants, like WD-40 or T-9, can eat away at the nickel in your instrument and cause serious damage. Wha other liquids can be used other than valve oil. Regular cleaning is arguably more important than the oil you choose! Don’t just keep applying fresh oil on top of old as eventually it will congeal and any new oil applied will make things worse rather than better. Clean your valves and valve casing out every couple of months and whichever oil you opt for should do the job just fine.

Hi all,
I'm just learning to write shell scripts (new to the whole UNIX thing) and I'm wondering if anyone would like to help me create a resource to help me, and others like me, learn scripting. It would be something like '100 interesting shell scripting problems'.

My motivation / reasoning is this: I've been learning for a while, but as I'm doing it for pleasure (not for work), I don't really

need to write a lot of shell scripts. I've already written a few simple scripts to automate some of my daily tasks, but I want to take my scripting to the next level.
I've got a lot of great books, tutorials, web pages, etc. to help me learn, but they are mostly used for reference, as the examples they include are rather general / trivial, and they don't have many exercises.
Basically, I have a lack of 'interesting problems to solve' and therefore a lack of real learning opportunities and practice. I know that others have the same problem too.
So, I'm looking to create a list of practical, interesting, real-world problems which gradually increase in difficulty. It will be similar to thekarangoel's git repo 'Projects' where you can learn Python by solving the problems given (sorry, can't post links yet).
As an example, in case I'm not making myself clear, there could be a list of categories, such as:
- Account Admin
- Backup
- Games
- Networking
- File manipulation
- etc.
Each category would contain a number of problems to solve. Some (rubbish) examples might be:
- Create a script which counts the number of users currently logged in.
- Create a script which backs up all the dotfiles for the current user.
- Create a script which converts all file names to lowercase and removes whitespaces.
- Create a script which converts Markdown formatted text into HTML files.
It will be a kind of learn-by-doing system. The learner will be responsible for finding the information and resources necessary to solve the problem, and may upload his solution for others to study. The problems could include difficulty ratings, hints / tips, suggestions or links to solutions or helpful resources to aid the learner, if need be.
I would make the resource available online as a webpage, wiki, git repo, ebook, or whatever else people want.
As I said, I'm happy to do the heavy lifting myself, but lack of knowledge / experience stops me from creating

meaningful problems

, or even decent categories of problems / tasks.
Any feedback, help or suggestions would be very much appreciated, but as stated at the beginning all I need to get started are suggestions for interesting problems to solve using shell scripting.
Thank you,
