Hello hanson44,

It's not working :frowning:

Below is my output:


[root@dhcppc116 files]# ls
appp1.APP.RTP.DEV1  appp2.APP.RTP.DEV1  appp3.APP.RTP.DEV1
[root@dhcppc116 files]# rename 's/RTP/mmk' *.DEV1
[root@dhcppc116 files]# ls
appp1.APP.RTP.DEV1  appp2.APP.RTP.DEV1  appp3.APP.RTP.DEV1
[root@dhcppc116 files]# 

[root@dhcppc116 ~]# uname -a

Maybe the following glitch?

rename 's/RTP/mmk' *.DEV1

vs

rename 's/RTP/mmk/' *.DEV1

Or maybe you just made an error when you copied and pasted?

I will try that , anyway i solved it by following code :

for i in *.DEV1
do
fname1=`basename $i .RTP.DEV1`
mv "$i" "$fname1.mmk.DEV1"
done

Thanks!!

Yes, the short shell script is a fine way.
