How can I bulk copy files to a new extension in the same directory?
Ok, I'm at a loss on this one. What I frequently need to do is take a group of files in a directory, copy them so they have a different extension and have the new files remain in the original directory. For example, if I have file1.cfg, file2.cfg and file3.cfg in /dir I want to be able to copy them so I have file1.txt, file2.txt and file3.txt in /dir in addition to file1.cfg, etc... When I'm done I want to have all six files in /dir. This is very simple in Windows:
Don't forget about quoting though (also this can be done without bash extensions):
Code:
for i in *.cfg; do
cp "$i" "${i%.cfg}.txt"
done
Of course you can use basename instead of Bash extensions, like we did, but Bash is pretty much a common denominator nowadays, I would think, so why not take advantage of it (and I tested this also on zsh, works there, too).

Sure, that's why this was just a minor point of my post – my main issue was with quoting.
Nonetheless I prefer sticking to POSIX shell (which may be especially useful when writing scripts as programs like dash are reported to be faster than full bash) and “${i%.cfg}.txt” is in no way less convenient than “${i/%.cfg/.txt}”.
By the way, I think it's also worth noting “rename” here. Potential solution to OP problem could also be:
Code:
cp -- source-directory/*.cfg target-directory/
cd target-directory/
rename .cfg .txt *.cfg
# or on systems with perl-based rename:
# rename 's/\.cfg$/.txt/' *.cfg
