Find all files with .md extension and execute a command with the file and generate a new file with a name generated through the the md file name - html

Question

I'm trying to write a shell script to recursively find all files under a directory with the extension .md and execute a command with the .md file and generated new file with the same name but a different extension.
below is the command I'm having but its actually appending the .html to the file instead of replacing .md with .html
find . -name '*.md' -exec markdown-html {} -s
resources/styles/common-custom.css -o {}.html \;
the above command generates a new file "home.md.html" from "home.md" but i want the .md removed. tried different solutions but didn't work

Hi you have to write a small script here, I have given the description how it is going to work, please refer to the comments in the below codes:-
First create a shell script file like convertTohtml.sh and add below codes in it
#!/bin/bash
find . -name '*.md' > filelist.dat
# list down all the file in a temp file
while read file
do
html_file=$( echo "$file" | sed -e 's/\.md//g')
# the above command will store 'home.md' as 'home' to variable 'html_file'
#hence '$html_file.html' equal to 'home.html'
markdown-html $file -s resources/styles/common-custom.css -o $html_file.html
done < filelist.dat
# with while loop read each line from the file. Here each line is a locatin of .md file
rm filelist.dat
#delete the temporary file finally
provide execute permission to your script file like below:-
chmod 777 convertTohtml.sh
Now execute the file:-
./convertTohtml.sh

Below script will work to solve the extension problem.
#!/bin/bash
find . -name '*.md' > filelist.dat
# list down all the file in a temp file
while read file
do
file=`echo ${file%.md}`
#get the filename witout extension
markdown-html $file -s resources/styles/common-custom.css -o $file.html
done < filelist.dat
# with while loop read each line from the file. Here each line is a locatin of .md file
rm filelist.dat
#delete the temporary file finally

If you want to use the output of find multiple times you could try something like this:
find . -name "*.md" -exec sh -c "echo {} && touch {}.foo" \;
Notice the:
sh -c "echo {} && touch {}.foo"
The sh -c will run commands read from the string, then the {} will be replaced with the find output, in this example is first doing an echo {} and if that succeeds && it will then touch {}.foo, in your case this could be like:
find . -name "*.md" -exec sh -c "markdown-html {} -s resources/styles/common-custom.css -o {}.html" \;
