Clone site and remove query string values from the files in linux.

clone site using wget.txt

# Clone entire site.
    wget --content-disposition --execute robots=off --recursive --no-parent --continue --no-clobber http://example.com

# Remove query string from a static resource.
    for i in `find $1 -type f -name "*\?*"`; do mv $i `echo $i | cut -d? -f1`; done

For the last line we need to create a file rename.sh
Write inside:

# /bin/bash
for i in `find $1 -type f -name "*\?*"`; 
  do mv $i `echo $i | cut -d? -f1`; 
done

then make this file exacutable:
chmod +x rename.sh
and call with folder path as an argument (in this case dot represents current folder):
rename.sh .

OK here is the new version for 2024
