Shell Programming and Scripting

find . -type f -print | while read file
do
    file_clean=$( echo ${file} | tr " ()&'" "_____" )
    echo $file $file_clean
done

That script will fail for many reasons.

First, you don't want to find all files, only those whose name contains a space:

Code:

find . -type f -name '* *' -print |

Second, your read loop will strip leading or trailing spaces from the filenames (probably not a problem, but you never know) and remove any backslashes (also probably not a problem, but why risk it?):

Code:

 while IFS= read -r file

Third, modern versions of tr do not require the replacement to be repeated:

Code:

file_clean=$( echo "$file" | tr " ()&'" "_" )

Fourth, the mv line will fail when a filename contains a space (which, given the problem you are trying to solve, is always).

Code:

echo "$file" "$file_clean"

In bash and ksh93, you don't need tr:

Code:

file_clean=${file//[ ()&\']/_}
