Newbie Bash scripting question

Caidence · 08-03-2003, 02:35 AM

Anyone know of anyway out there I can get ls to either

a.) give me all of the subdirectories in a directory

or

b.) give me all of the files of type *.spam in the current directory and all subdirectories in a format suitable to be read into a for loop's sentinel array?

What I'm trying to do:
I have a webpage that I preproccess with gcc, and output the HTML to another production directory.

I want to write a script that will find all of the source files in one directory, compile them, and place them in a parallel directory in the production directory... then do the same for all subdirectories.

ls's -R option gives everything in a sectional listing rather than a literal one, with every file preceeded by the directory it's located in.

Also, I can't find an ls option that only returns directories.

Perhaps I should be ls-ing the whole directory and finding a way in bash script to parse the filenames for their extensions?

I'm really a newbie in this area. Thanks for reading!

Well, to list all the subdirectories, you can do something like

ls -RF | grep \/

When you have all the subdir's then you can go through these on an ordinary loop, and list the appropriate files.

Code:

#!/bin/bash

for dir in `ls -RF | grep \/ | tr \: \/` ; do
   for file in `ls $dir/*.c` ; do
      gcc $file <whatever options>
   done
done

Or not

The "tr \: \/" pipe only exchanges the trailing ":" to slashes, to avoid errors.

Find would be much better for this:
find . -type d
Would show all the directories in the tree.
find . -name *.spam -print
Would find all the *.spam files.
