Question

i have directory that has 2 sub-directories and that again has few sub-directory and they have some files. I need to rename all the files to append an html extension to the filenames.
the directory structure looks like this

main-directory
   sub-directory
   sub-directory
       sub-directory
          file1
          file2
          and so on to lot of files

now i could not use something like this

for file in main-directory/*
do
if [ -f "$file" ]
then `mv "$file" "$file.html"`
fi
done

because the for loop wont use the path recursively. so i used something like this

for file in `ls -1R main-directory`  // -1 for showing file and directory names separated by new lines and -R for recursive travel
do
if [ -f "$file" ]
then `mv "$file" "$file.html"`
fi
done

the above code is not able to rename files. to check whether the line

for file in `ls -1R main-directory`  

is working i wrote something like this

for file in `ls -1R main-directory`
do
if [ -f "$file" ]
echo $file
done

this doesn’t show anything. what can be wrong?

Answer 1

you can use find and look into of type file and then -exec to change all the file and then appending the .html.

find main-directory -type f -exec mv -v '{}' '{}'.html \;
