Renaming part of a filename [duplicate]

Question

I have loads of files which look like this:

DET01-ABC-5_50-001.dat ... DET01-ABC-5_50-0025.dat 

and I want them to look like this:

DET01-XYZ-5_50-001.dat ... DET01-XYZ-5_50-0025.dat 

How can I do this?

Answer 1

There are a couple of variants of a rename command, in your case, it may be as simple as

rename ABC XYZ *.dat 

You may have a version which takes a Perl regex;

rename 's/ABC/XYZ/' *.dat 

Answer 2

for file in *.dat ; do mv $file ${file//ABC/XYZ} ; done 

No rename or sed needed. Just bash parameter expansion.
