BASH：使用中缀批量重命名文件

Question

I have files '/my/file_{01...10}.mat' that I'd like to rename to '/my/file_ABC{01..10}.mat' such that 'file_01.mat' becomes 'file_ABC01.mat', 'file_02.mat' > 'file_ABC02.mat',... and so on.

I've found a number of ways to append strings in a script but nothing (that I understand) to infix strings. Suggestions? Thanks!

Answer 1

应该这样做：

for f in /my/file_*.mat; do mv $f ${f/_/_ABC}; done
