Newb question about getting a word from a text file

Hi everyone.

I am new to shell scripting and have been looking at quite a few web pages to try and figure this out, but to no avail.

What I am trying to do is get a value from a text file that contains a paragraph of information.. Something similar too:
Welcome to random script
You are using the task XXXXXXX
The value for this task is 2.302E-4
I hope this helps

So that is basically what is in the file. Now, what I am trying to do is get the 2.302E-4 value and then use it as a variable in my script.

So far all I can find is how to output an entire line from the file.

Is there a simple way to get this value? I was thinking that their might be an array with lines and words? line[2] word[6] or something of that manner?


Any help/assistance/tips would be greatly appreciated.

The default width is 72. concatenates the arguments. If none are given, formats text from the standard input. Blank lines are preserved in the output, as is the spacing between words. does not fill lines beginning with a period for compatibility with Nor does it fill lines starting with Indentation is preserved in the output and input lines with differing indentation are not joined (unless is used). can also be used as an in-line text filter for the command: reformats the text between the cursor location and the end of the paragraph. Options recognizes the following options: Crown margin mode. Preserve the indentation of the first two lines within a paragraph and align the left margin of each subsequent line with that of the second line. This is useful for tagged paragraphs. Split lines only. Do not join short lines to form longer ones. This prevents sample lines of code, and other such "formatted" text, from being unduly combined. Fill output lines to up to width columns. WARNINGS
The width option is acceptable for BSD compatibility, but it may go away in future releases. SEE ALSO
