# Pattern Arguments

For file-related options, such as the output file name or the error file name, you can use a pattern-matching argument. For example, if you specify the option -i "run", Condor looks for an input file with the name run. If there is no file named run, Condor looks for a file name that begins with run., such as run.14.

If there are multiple files with names that begin with the pattern that you specify, then for the first execution within a cluster, Condor uses the file with the name that matches first in alphanumeric order. For successive executions within a cluster, Condor uses the files with names that match successively in alphanumeric order.
