Linux – Run commands on multiple files and keep the same name

How do I run shell commands on multiple files in Linux/Mac while keeping the same name (excluding extension)?

For example, let’s say I want to use the command to compile a list of files into some other file with the same name:

{command} [name].less [same-name].css 

EDIT: More generally, assuming the two targets are in two different paths, such as “path/to/folder2” and “path/to/folder3”, keep in mind that you can always specify in a for loop, you can try:

for i in $(ls path/to/folder3 | grep .less); do . /path/to/folder1/script.sh  $(echo "path/to/folder3/$i $( echo "path/to/folder2/$i" | sed -e s/.less/.css/)") ; done

Still sorry for the cruel and possibly inelegant solution.
