ファイル名またはフォルダ名の先頭または末尾のスペースを削除します

• To remove any number of leading spaces from file names you can use rename (prename) :

  rename -n 's/^ *//' *
  

• To remove any number of trailing spaces from file names you can use rename (prename) :

  rename -n 's/ *$//' *
  

  Remove -n (dry-run) if you are satisfied with the file names.

• To remove files or folders that are empty (recursively) :

  find . -empty
  

  Satisfied ? Let the action take place :

  find . -empty -delete
  

  Only in the current directory :

  find . -maxdepth 1 -empty -delete
  

  Also use -type f for only files and -type d for only directories if you want.

Read man rename and man find to get more idea.

For removing spaces, several approaches here: https://stackoverflow.com/questions/2709458/bash-script-to-replace-spaces-in-file-names https://stackoverflow.com/questions/15347843/remove-whitespaces-from-filenames-in-linux

This easy one: "First enter directory with cd: cd /my/directory and then run: for f in *; do mv "$f" echo $f | tr ' ' '_'; done"

Even simpler: "rename "s/ //g" *"

For getting rid of spaces, underscores, and hyphens: "rename -i "s/[-_ ]//g" *"

For getting rid of files that have zero bytes: https://stackoverflow.com/questions/5475905/linux-delete-file-with-size-0

For handling either empty files or folders, I found this one: "Delete empty files (remove 'echo' from the command): Code: find . -empty -type f -print0 | xargs -0 echo rm Delete empty directories (remove 'echo' from the command): Code: find . -empty -type d -print0 | xargs -0 echo rmdir" http://www.linuxquestions.org/questions/programming-9/bash-delete-empty-files-910203/

Seems odd that I answered my own question in the space of a half hour, but that is the power of a search engine if you pick the right words to search on. However, there are terms and conditions asked that produce no ready answers, such as with another question I had posted here the other day. I researched it hard first, found no results, so posted it on AskUbuntu. I've checked, and still no answer. May have to go back to doing searches, if I can think of what else to ask.

I often forget about rename. Here's how to do it with plain bash:

$ touch "     leading spaces" "trailing spaces     "

$ printf ">%s<\n" *spaces*
>     leading spaces<
>trailing spaces     <

$ for f in *spaces*; do 
    new=${f##*([[:blank:]])}        # remove leading whitespace
    new=${new%%*([[:blank:]])}      # remove trailing whitespace
    mv "$f" "$new"
done

$ printf ">%s<\n" *spaces*
>leading spaces<
>trailing spaces<
