search through files and put into array

cat `find . -name '*.css'`

This will open any css file. I now what do two things.

1) How do I add *.js to this as well. So I want to look inside all css and javascript files.

2) I want to look for any css or image files within those (css or js files) and push those into an array. So I guess look for a .png, .jpg, .gif, .tif, .css and put everything before that until the quote or single quote into an array. I want an array because this command will go into a shell script and after I get all the names of the files that I need I will need to loop through and download those files later.

Any help would be appreciated.

Extra hackery, in case someone needs it:

find ./ -name "*.css" | xargs grep -o -h -E '[A-Za-z0-9:./_-]+\.(png|jpg|gif|tif|css)'| sed -e 's/\.\./{{url here}}/g'|xargs wget

will download every missing resource

1) simple answer: you can add the names of all .js files to your cat command, by instructing find to find more files:

cat `find . -name '*.css' -or -name '*.js'`

2) a text-searching tool such as grep is probably what you're after:

find . -name '*.css' -or -name '*.js' | xargs grep -o -h -E '[A-Za-z0-9:./_-]+\.(png|jpg|gif|tif|css)'

Note: my grep pattern isn't universal or perfect, but it's a starting example. It matches any string that includes alpha-numeric,colon,dot,slash,underscore or hyphens in it, followed by any one of the given extensions.

The -o option causes grep to output only the parts of the .css/.js files that match the pattern (i.e. only the apparent filenames).

If you want to download them you could add | xargs wget -v to the command, which would instruct wget to fetch all those filenames. NOTE: this won't work for relative filenames; some other magic will be required (i.e. you'll have to resolve them with respect to the grepped file's location). Perhaps some extra hackery, such as sed or awk.

Also: How often do you see references to TIFFs in your CSS/JS?

Do the command:

find ./ -name "*.css" -or -name "*.js" > fileNames.txt

Then read each line of fileNames.txt in the loop and download them.

Or if you are going to use wget to download the images you could do:

find ./ -name "*.css" -or -name "*.js" | xargs grep '*.png' | xargs wget

May need a little refinement like a cut after the grep but you get the idea
