In a directory a number of files named res0.om res1.om ... resN.om

where N can be any unknown number between 1 and 999

Please help me filling out the gaps in the following csh script:

I need to delete all files exept res0.om The easy way is

rm res1*
rm res2*
rm res3*
rm res4*
rm res5*
rm res6*
rm res7*
rm res8*
rm res9*

but that gives a lot of ugly error messages in case N < 9.

Can i use something like:

if (res9* exist) rm res9*

?
