Bash script to rename all files in a directory

Question

I have a directory with a bunch of files names like this:

DetailedFeatureNameIntegrationTest.java

and I want to rename all the files to

DetailedFeatureNameIntegTest.java. 

I just want to replace 'Integration' with 'Integ' is there a quick way to do this?

Answer 1

Using pure bash ,

for f in *.java; do
    mv -- "$f" "${f//ration/}"
done

assuming you don't have a situation like both DetailedFeatureNameIntegrationTest.java and DetailedFeatureNameIntegTest.java already in the same directory.

Answer 2

使用perl rename实用程序：

rename 's/Integration/Integ/' *.java
