Change file extension of several files in one command - bash

Question

I'm using a binary to convert a file type to another:
./rcc -binary themes/redTheme.qrc -o redTheme.rcc
I have several .qrc files and would like to convert them as well, but in the same command. How to regroup them rename and their type? I'm struggling to find a way to keep the file name.
I was thinking about binding my rcc binary to a pipe that would execute a loop converting the .qrc files.

Answer 1

I hope you can bind this with your binary:
ls *.qrc | xargs -I {} sh -c 'mv $1 `basename $1 .html`.rcc' - {}

Answer 2

You could use something like this:
$ for i in *.qrc ; do echo mv -v ${i} ${i%.qrc}.new ; done
See here an example where I have a couple of files with qrc ending and I mv them to .new
$ l

-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 1.qrc
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 10.qrc
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 2.qrc
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 3.qrc
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 4.qrc
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 5.qrc
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 6.qrc
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 7.qrc
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 8.qrc
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 9.qrc
$ for i in *.qrc ; do mv -v ${i} ${i%.qrc}.new ; done
1.qrc -> 1.new
10.qrc -> 10.new
2.qrc -> 2.new
3.qrc -> 3.new
4.qrc -> 4.new
5.qrc -> 5.new
6.qrc -> 6.new
7.qrc -> 7.new
8.qrc -> 8.new
9.qrc -> 9.new

-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 10.new
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 2.new
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 3.new
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 4.new
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 5.new
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 6.new
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 7.new
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 8.new
-rw-r--r-- 1 chl wheel 0 Mar 9 16:22 9.new
$
Of course you have to use your rcc tool instead of mv and use your ending instead of .new
