I have a file , the file content will be modified regularly , its structure as below, the lines are begins with "A" and "B" .
#vi file1
I would like to have a script to use the information in file1 to generate another file , so that when run the script , it will generate another file as below format , would advsie what can I do ? thanks
Is my_string a constant, or is it a parameter to your script?
What have you tried to solved this problem?
Are the blank line and the this is a testing file in file1? Are the A and B lines always in that order? Are there ever other lines between the A and B lines?
Is this a homework assignment? ==> this is not homework assignment .
Is my_string a constant, or is it a parameter to your script? ==> my_string is a constant
What have you tried to solved this problem? ==> sorry , I am new to script writing . I tried read something but still not find any idea.
Are the blank line and the this is a testing file in file1 ? ==> in file1 , there are blank line and have other line not begins with "A" or "B" .
Are the A and B lines always in that order? ==> yes , A then B
Are there ever other lines between the A and B lines? ==> No other lines.
Instead of generating the file2 after each time run the script , is it possible to append the new lines to file2 ? for example , if there is the following new lines in file1 .
then append the following new line to file2 rather than re-generate file2 ?

Write a script named time that displays the time in standard 12-hour format, rather than 24-hour format. Allow the user to give a -m option to get 24-hour format. For example:

Sun Feb 10 10:56:50 CST 2008
> time
10:56 AM
> date
Sun Feb 10 21:57:07 CST 2008
