I have bunch of files in one directory, like these:
0002.b3120c4bcbf3101e661161ee7efcb8bf
0003.acfc5ad94bbd27118a0d8685d18c89dd
0004.e8d5727378ddde5c3be181df593f1712
0005.8c3b9e9c0f3f183ddaf7592a11b99957
And so on...
And I want to rename them to something easier to manipulate in a script:
2
3
4
5
And so on...
How to do it in Linux shell or script?
