Question

I have this command to go to every directory and once there run some command over every file:

STDIR=$PWD;
for dir in $(find . -type d 2>&-); do 
    cd "$dir";
    for file in $(find * -prune -type f 2>&-); do 
        command "$file";
    done; 
    cd "$STDIR"; 
done

But there is a problem when the files or directories have spaces in the name. How can I fix that?

This doubt appear when trying to apply an answer to this question.

Edit:
A good solution also appear in this comment. To solve the spaces problem, add

IFS=$'\n'

after the first line of the code above, and

unset IFS

after done.

Answer 1

There are three ways:

1) find -exec (see the answer from Sorpigal)
2) find ... | xargs
3) find ... | while read line ; do command "$line" ; done

The third solution has an advantage: you need not so many forks as in the variants (1) and (2). And when you need to process quite many lines it can become important.
