Rename file in bash script

I found that how to rename multiple file in bash script had been already asked. I have checked all answers. However, I could not solve my problem. I would like to find all files with certain name in a given directory. Then, I would like to rename all files accordingly. I need all diectories starting with 'lattice' and also need files starting with 'POSCAR.' in lattice directories. I have many directories starting with 'lattice'

This is what I have tried. Bash gives error like "they are the same files"

match=POSCAR.
replace=POSCAR
for D in *lattice*
do echo "$D"
  for file in $(find $D -name "*POSCAR*")
  do
    echo "$file"
    src=$file
    tgt=$(echo $file | sed -e "s/*$match*/$replace/")
    fnew= `echo $file | sed 's/*POSCAR/POSCAR/'`  
    mv $src $tgt
  done
done

You can try something like this 

find lattice* -type f -name 'POSCAR.*' \
    -exec bash -c 'echo mv -iv "$0" "${0/POSCAR./POSCAR}"' '{}' \;

Remove the when you're sure it does what you want. Note this assumes, you don't have some POSCAR. directory earlier in your path.

Not also, *WORD* matches files with WORD anywhere. WORD* matches files that start with WORD. Also, I'm assuming you mean that POSCAR.* are regular files (i.e. not directories or symlinks, so I included the -type f.

Perhaps rename tool may help you.

rename 's/POSCAR\./POSCAR/' *lattice*

All you need is the right find syntax and the right bash string manipulation

while read -d $'\0' -r file; do

  # // replaces all matches. If you want only the first one use /
  newname=${file//POSCAR./POSCAR} 
  mv "$file" "$newname"

done < <(find \( -ipath '*/lattice*' -and -iname 'POSCAR.*' \) -print0)
