Expansion within cp

I have a bunch of files which I need to transfer to another location... and some of these I need to skip.

For e.g. let us say the files are:


Code:
cust_abc.dat
cust_xyz.dat
cust_def.dat

and I only want to move the first two.

I want to do something like:


Code:
cp cust_[/abc|xyz/].dat <target>

which doesn't work due to bad syntax. Is there some way of doing this without involving grep and xargs? I would like to do it with a single command if possible...

Based on your pattern attempt, I assume bash if you are excluding one filename


Code:
# set extglob on -- shopt will show it's status
shopt -s extglob
cp !(def_cust).dat /somewhere

The not (!) operator means do not match. You can have multiple pipe-delimited patterns
See the section on 3.5.8.1 Pattern Matching here:
Bash Reference Manual

You may want to go with another pattern/way.
