Need a quick bash script - bash

Question

I have about 100 directories all in the same parent directory that adhere to the naming convention [sitename].com. I want to rename them all [sitename].subdomain.com.
Here's what I tried:
for FILE in `ls | sed 's/.com//' | xargs`;mv $FILE.com $FILE.subdomain.com;
But it fails miserably. Any ideas?

Answer 1

Use rename(1).
rename .com .subdomain.com *.com
And if you have a perl rename instead of the normal one, this works:
rename s/\\.com$/.subdomain.com/ *.com

Answer 2

Using bash:
for i in *
do
mv $i ${i%%.com}.subdomain.com
done
The ${i%%.com} construct returns the value of i without the '.com' suffix.

Answer 3

What about:
ls |
grep -Fv '.subdomain.com' |
while read FILE; do
f=`basename "$FILE" .com`
mv $f.com $f.subdomain.com
done

Try this:
