从命令行重命名文件

Posted 2021-02-25

A couple of snippets useful for file management. I use these to make sure I understand how many files I'm about to modify, and then rename them.

## Use find to search for the files I want recursively from the current path
## Powerful utility, man find to read the man pages
 
find . -name "*.rhtml"   # List all files that end in .rhtml
find . -type f           # Find all regular files 
 
 
## I can use wc (word count) with the -l flag to count the number of returned lines
 
find . -name "*.rhtml" | wc -l    # Count the number of files that match
 
 
## I can then add a while and mv command to rename the files
 
find . -name "*.rhtml" | while read f; do mv ./"$f" "${f%rhtml}html.erb"; done
