Linux: Rename files from uppercase to lowercase

If you have downloaded Oracle 18c installation files, you may need to change downloaded file  names from uppercase letters into lowercase. 🙂

[root@rac1 ~]# cd /sw
[root@rac1 sw]# for i in LINUX.X64_180000_*; do mv $i `echo $i |tr [:upper:] [:lower:]`; done

You may think these are just two files and why I need script? I can do it manually.. 🙂
You are right , but scripting is much more fun. Good luck!
