bash scripting challenge

Question

I need to write a bash script that will iterate through the contents of a directory (including subdirectories) and perform the following replacements:

• replace 'foo' in any file names with 'bar'
• replace 'foo' in the contents of any files with 'bar'

So far all I've got is

find . -name '*' -exec {} \;

:-)

Answer 1

With RH rename:

find -f \( -exec sed -i s/foo/bar/g \; , -name \*foo\* -exec rename foo bar {} \; \)

Answer 2

find "$@" -depth -exec sed -i -e s/foo/bar/g {} \; , -name '*foo*' -print0 |
while read -d '' file; do
    base=$(basename "$file")
    mv "$file" "$(dirname "$file")/${base//foo/bar}"
done
