Shell or Perl Scripts

Hi,
I am to new to scripting and I have a urgent requirement that I should do. The requirement is.

A shell script that reads a directory and its sub directories and generate a flat file or csv file at the end so that I can use that file to load data into my tables.

Please very urgent.

Thanks in Advance

What part of your script are you having problems with? for the most part you could do something like

find $1 -print >> filestruct.csv

The $1 would allow you to give a top level directory. Now you will need to refine that a bit to remove the filenames that come up.

Ok, do you want a list of the files or of their contents? You just got suggestions for both...

I am a little confused on what you are actually looking for. However
if you are wanting to find just the directory structure you could do the following

Code:

find . -type d > myTree.csv

this would get all directories only from the current working directory. If you are placing this in a batch script replace . with $1 so you can specify a directory from outside the directory.

for getting a list of all files then you could do the following

Code:

find . -type f > myTreeFile.csv

again change as needed.

It is easy to generate a flat file or CSV file. Doing so with the desired contents will require more information. What information is to go into the file? By your description of the problem, the following bash script satisfies the requirements:

Code:

#! /bin/bash

find $1

echo foobar > flatfile.csv

When describing a problem, do not forget that the reader knows absolutely nothing about the problem domain, beyond what you provide. Be complete and concise.

We are not here to do your homework for you. If you want to work in the computer field, you need to do the work yourself. That means spending time researching, reading, trying different things and making lots of mistakes from which you learn. That is what we have done. We volunteer our time on forums to help newbiew and each other.

Don't just come here and ask us to do your assignments. Think about something, your instructor most likely reads these forums also and likely will be wise to your methods.

You also never explained what the problem really is!

If you at least want a chance of us helping, you must post the exact specs of the output file to the last detail, because we can't read your mind.

Sorry but i'm giving him a script.

Code:

#!/bin/bash



DIR=/dir/subdir



ls -alR ${DIR} > flatfile.txt

The -R option with the ls command shows subdirs recursive.
