Changing multiple filenames with a script

brecki · 01-30-2004, 01:58 PM

howdy,

I hava a directory that contains around 200 files with the following naming scheme: CCTP.asm, CCAS.asm, etc. I want to change all of those file names to CCTP40.asm, CCAS40.asm, etc. Basically, I want to add 40 to the end of each file name.

How can I do this in a simple script?

Thanks in advance

'man rename'

code:
---
rename .asm 40.asm *.asm
---

rename all files from .asm to 40.asm using mask of *.asm

Try this...

for i in *.asm; do j=`echo $i | awk -F. '{print $1"40.asm"}'`; mv "$i "$j"; done

That won't work. You have to keep the original 4 characters of the name and the .asm extension. In other words, the file CCAW.asm needs to be changed to CCAW40.asm. This needs to be done in a for loop for over 200 files.

Therefore, I must seperate the CCAW part from the extension part of the filename and append 40 to CCAW and then append .asm to that.

In order of commands:

---
[xxx@xxx xxx]$ ls *.asm
CCAS.asm CCAW.asm CCTP.asm
[xxx@xxx xxx]$ rename .asm 40.asm *.asm
[xxx@xxx xxx]$ ls *.asm
CCAS40.asm CCAW40.asm CCTP40.asm
---

Isn't that the results you would like?
