Unless you also want to delete files in subdirectories of your current directory, using find to get the list of files with names ending in .trc is grossly inefficient compared to ls *.trc. Unless you're on a system with a small value for ARG_MAX, you can skip using xargs as well using:
Code:
rm $(ls *.trc|grep -F -v -e dasd_91197.trc [-e dasd_other.trc]...)

The standards allow ARG_MAX to be as small as 4096, but on OS X it is 262144. You can find the value on your system using:
Code:
getconf ARG_MAX

If the value returned is likely to be smaller than the number of bytes needed to hold the names of the files you'll be removing plus any environment variables you're exporting, you'll need to keep the xargs element of the pipeline rather than using the above form of command substitution.
