linux - Removing Special Characters and bulk renaming -

I am trying to create a shell script for removing special characters, like {} () !, 'etc. . So far I have referred here to a previous question, but I get a strange error message:

  -bash-3.2 $ ./test2.sh ./test2.sh: line 7: Unseen EOF `` './test2.sh To Match: Line 10: Syntax Error: Unexpected End of File  

test2.sh

  #! / Bin / Bash shopt -s nullglob * if file for [-f "$ file"]; So newfile = "` $ echo $ file | tr-d '[{} (), \!]' | Tr-d "\" "|  

Not sure if I Why are you going wrong on this, files are named I / O:

  folder - 01 folder 02! Folder (03) folder four_thread  

the desired output

  folder 01 folder 02 folder 03 folder four three  

Thank you in advance.

for shopch -s extglob shopt -s for nullglob in;; echo "mv $ i $ {i // [[: punct:]] / } ";
