UNIX for Dummies Questions & Answers

I searched and tried many answers from similar questions on this forum, but none of them finished my job. Maybe I am too novice to unix. Sorry I have to ask again,and hope I can get the answer.

I have a folder with files
sqcu001v.jpg,
sqcu002v.jpg,
...
sqcu100v.jpg.

I want to have them renamed to
dscu001v.jpg,
dscu002v.jpg,
....

That is, I want to change all the sqcu*.jpg to dscu*.jpg. What script can do the job?

Thanks a lot.

Code:

for SFILE in `ls sqcu*v.log`; do
  TFILE=`echo ${SFILE} | sed 's/sqcu/dcsu/'`
  mv ${SFILE} ${TFILE}
done

If you have the rename program:

Code:

rename sq ds *jpg

If you have zsh:

Code:

autoload -U zmv
zmv  'sq*jpg' '$f:s/sq/ds/'

Otherwise:

Code:

for f in sq*jpg; do
  mv "$f" "ds${f#??}"
done

Thank you very much, guys! They worked for me successfully! I wasted about 2 hours trying to play with it, but I failed. Now I got my answer in 5 minutes!
