find . -size +110M -size -150M -exec cp {} /home/adam/files/ \;

This article is great. Maybe the best I’ve read on the
subject. Thanks…

Also, you don’t have to pipe find to xargs for an rm. -delete works just as well.

Btw, ls and rm don’t actually accept regexps. They will, however, accept globbing from bash, which is what your examples end up producing.

Regexps can also strip HTML from files, ie
cat file.html|sed -e ‘s/]*>//g’ >> file.txt

You can also make find’s -regex option case insensitive by making it -iregex. This is handy when you’re searching through a mixed environment of upper case and lower case file extensions like jpg and JPG.

And don’t forget, the rename command also accepts regexps!
For instance, if you want to change the case of some JPG files to lower case:

cd ~/photos/dirwithphotos
rename ‘s/JPG$/jpg/’ *.JPG

Done.
You can go further with it, too. For instance, if I want to change the first part of the filename, since they’re all named IMG_0123.JPG

cd ~/photos/icanhaslinux
rename ‘s/^IMG/icanhaslinux/’ *
rename ‘s/JPG$/jpg’ *

It accepts very sed-like regexp behavior.

Anyway, that’s all for now!
