Can anyone help me with these scripts?

[cewan]

Hi, I'd like to have some scripts perform the following tasks for me:

1. usage: collectfiles <sourcefolder> <destfolder> <extensionlist>
This script would walk through all folders in <sourcefolder> and whenever it finds a file with an extension matching any extension in <extensionlist>, the file will be moved to <destfolder>
example: collectfiles . myMovies avi,mov

2. usage: spacify <sourcefolder>
This script would walk through all folders in <sourcefolder> and whenever it finds a file or directory having a name that contains underscore ('_') it will be replaced with a space (' ').

3 usage: capitalize <sourcefolder>
This script would walk through all folders in <sourcefolder> and for every folder and file each word in it's name will be capitalized, i.e. the first letter of the word will be changed to upper case.
example: capitalize my\ folder
will result in the folder changing name to 'My Folder'.

Anyone have any hints, complete solutions or guidance? Is it even possible to write such scripts?
BR,

1:This script would walk through all folders in <sourcefolder> and whenever it finds a file with an extension matching any extension in <extensionlist>, the file will be moved to <destfolder>
example:
Code:

collectfiles . myMovies avi,mov
find . -type f \( -name "*.avi" -o -name "*.mov" \) -exec mv {} /full/path/to/myMovies \;

Edit: Do your own homework. :D

Oh, that's a nice one! Thanks alot :)

1 down, 2 to go

It is hard to know where to search for these kinds of stuff. I guess it comes by experience, right? I am a real newbie to Linux, wasted all my life with Windows and just discovered Linux like a month ago. Now I use Linux both at work and at home =)

Would be grateful for help on the other scripts as well!

Haha, I am really impressed, you know your scripting!

2 down! Is the third too hard? ;-)

[yabbadabbadont]

The last isn't very hard either. However, as most professors would say, "the rest is left as an exercise for the student." :D

Hint:
man sed
man tr

(in addition to the programs I used previously)

[cewan]

That's a good reply! :-)
Now I know what I will spend my weekend on :-k

That looks like a decent place to start. I didn't read through too much of it, but it looked decent.
