How to replace all white spaces in file names in GCP Cloud Storage?

I have a bucket on GCP cloud storage and I want to rename all files that have a white space in their filename to the name where the whitespace is removed by a hyphen (-).

I tried something like

gsutil ls gs://<bucket>/<folder_with_the_files_to_rename>/ | sed 's/ /-/g/gsutil mv & \1/'

Unfortunately, I cant get the sed command work to replace the whitespace and then use the gsutil mv command to actually rename the file.

Can someone help me?

If you need to replace any space with - in some file names that you get with gsutil ls gs://<bucket>/<folder_with_the_files_to_rename>/, you can use

gsutil ls gs://<bucket>/<folder_with_the_files_to_rename>/ | \
  while read f; do
    gsutil -m mv "$f" "${f// /-}";
  done;

gsutil mv command moves/renames files, and ${f// /-} is a variable expansion syntax where each space is replaced with - (the // stands for all occurrences). Thus, you do not need sed here.
