This is the coursework, in Technical University Sofia, Bulgaria prof. Koshmarov, sorry but the link to the course is broken. And this is the condition:
Code:
1. If the value of x is 5, and you have been set a new value as such
x="expr $x + 10", What would be the value of x?
What would be the new value of the given variable if you had used single quotation marks and what should you do to obtain the same value in case of double quotation marks use?
2. Explain what would be the result of execution of the following command
$ `date`
3. In the command prompt set the following value of the variable x:
x='ls | more' или set x='ls | more' (C shell)
Can you execute $x? Why?
What is the difference between directory='pwd' and directory=`pwd`.
4. How can you interprete the command
set - *
within a command procedure?
5. If a given script is executed as foo -l -t bar[1-3], What would be the values of $# and $*? Will there be a difference if the options are combined?
6. Write a script that archives the files in the current directory not being modified in the last six months.
(Instruction: Use the commands find and tar or cpio.)
Just one of these helps me very much.
Thank you people!
