[Ubuntu] 一次刪檔案，除了…

文章出處：http://www.cyberciti.biz/faq/linux-bash-delete-all-files-in-directory-except-few/

雖然文章有提供二、三種方式，不過，我覺得下列的方法最簡單、實用：

## Delete all file except file1 ##
rm  !(file1)
 
## Delete all file except file1 and file2 ##
rm  !(file1|file2)
 
## Delete all file except all zip files ##
rm  !(*.zip)
 
## Delete all file except all zip and iso files ##
rm  !(*.zip|*.iso)
 
## You set full path too ##
rm /Users/vivek/!(*.zip|*.iso|*.mp3)
 
## Pass options ##
rm [options]  !(*.zip|*.iso)
rm -v  !(*.zip|*.iso)
rm -f  !(*.zip|*.iso)
rm -v -i  !(*.php)
