I've got a folder with numerous files in which I'd like to add the same
prefix to each.
For example on command line what would I enter to add "ADJ-" to the
beginning of each filename? I want two copies of each, one with and one
without the prefix and I don't fancy cp'ing each one manually.

This wont work because he wants "two copies of each, one with and one
without the prefix "

This should work:

for file in * ;
do
cp "$file" "ADj-$file"
done

This is faster than using find, but the OP asked for a copy
of each file with the modified name, not a change to the
modified name.

for i in *
do
cp $i ADJ-$i
done

Cheers!

Oops... missed that requirement

My counter proposal...

for file in * ;
do
ln "$file" "ADJ-$file"
done

and doesn't operate on subdirectories you need to use maxdepth to
prevent unintentionally altering other files

Also, it'll hit *all* files in that directory (iirc). Replace...:
for file in * ;
.... with...:
for file in $1 ;
.... if it's for a batchfile. If the for-done loop is being typed in at a
terminal window, replace...:
for file in * ;
.... with...:
for file in *.ext ;
.... to do the operation on files with a .ext extension.

Thanks Guys, for all the answers. I'm really going to have to get a
good book about trickier command line usage; anyone got any recommendations?

Recommendation: ask in this newsgroup how to solve a certain problem
using a script and you will get a lot of answers and instructions.

And don't worry: people like to post their (knowlegde about) scripts.
Making up *nix oneliners is even more fun than solving Sudoku's. ;-)

Please don't forget some awk and grep questions: fun guaranteed.
