递归重命名文件 Linux

Question

In Linux, I have a folder with files of the following names:

Abaraham test.txt 
Jacoobs_resulr.txt
Brabraim's test.txt 
....
Jamine.txt '

May I know how could I rename the files recursively to file1.txt ... file20.txt?

Answer 1

这将做：

cnt=0; for f in *; do [[ -f "$f" ]] && mv "$f" "file$f$cnt.txt" && cnt=$[cnt + 1]; done
