Rename file in shell script

Question

I need to find files of the form ' abc.111 ' in a directory and rename them as ' abc.222 ' in my shell script. The pattern substitution fails somehow. What am I missing here?

#!/bin/sh

find . -name \*abc\* | while read FILES
do
        newfile =  ${FILES/111/222} #Replace 111 by 222
        mv $FILES $newfile
done

Error : /temp.sh: bad substitution

Answer 1

Your /bin/sh does not support ${var//} substitution. Try another shell, such as /bin/bash .

Once you fix that, you will find that spaces do not work.

newfile =  ${FILES/111/222}

You must write this line without spaces on either side of = .
