Shell Programming and Scripting

Arrays? Files? One-line-files?

files with many lines but i have to make table using first element only.

Moderator's Comments:

There is no sample input, output, nor code in this post. So there shouldn't be any CODE tags.

First element of every file? First element of every line of every file? What are the parentheses in both input and output for?

Why don't you start over, spend a minute or two thinking, and give us a well defined specification with a few, representative sample input files, the logics needed, and the desired output?

In addition to what RudiC has already said...

Please help us help you!

Define your terms! Element could be a byte, a character, a word, a field, a line, a "group" of lines, or any number of other things? What constitutes an "element" in your input files?

You have repeatedly stated that the solutions given read entire files and that this is unacceptable. Why is is unacceptable? How big are your files?

What operating system are you using? Are there any restrictions on the set of tools you can use for this project? What is your preferred shell?

(And, please, use CODE tags to delimit sample input, sample output, and sample code; not entire posts.)

thank you. am sorry i can't make it understandable. i want to make table, out of first element of first line of every input file, input file don't have any brackets elements are separated by a comma(,). and out should be like

Code:

output file={1,1,1}

. output elements should be surround by parentheses({}).

Please do not leave people guessing. Show a representative sample of input, desired output, attempts at a solution and specify what OS and versions being used, or this thread will be closed.
