Shell脚本递归转换.md文件为.html文件的文件名问题求助

I feel you—those double suffixes are such a frustrating gotcha when working with find and -exec! The problem is that {} inserts the full filename (including the .md extension), so appending .html just tacks it right onto the end. Here's how to fix it properly:

The Corrected Command #

find . -name '*.md' -exec sh -c '
  for file do
    markdown-html "$file" -s resources/styles/common-custom.css -o "${file%.md}.html"
  done
' sh {} +

Why This Works #

Let’s break down the key bits that solve the filename problem:

• sh -c '...' sh {} +: This runs a single shell instance to process all found files at once (way more efficient than using \;, which spins up a new shell for every file).
• ${file%.md}: This is shell parameter expansion magic—it strips the shortest matching .md suffix from the filename. So home.md becomes home, and adding .html gives you the clean home.html you want.
• The for file do loop handles every file passed by find, making sure each one gets converted correctly.

Alternative: Using -execdir (For Per-Directory Processing) #

If your version of find supports -execdir (most modern ones do), this approach runs the command directly in the directory of each file—handy if your resources/styles path is relative to where the script runs:

find . -name '*.md' -execdir sh -c '
  markdown-html "$1" -s resources/styles/common-custom.css -o "${1%.md}.html"
' sh {} \;

Either method will eliminate those messy .md.html filenames and give you the clean, correctly named HTML files you’re after!
