Readers, File 1 contains data:
/some/text/abcd.xyz File 2: abcd.xyz The manual does not seem to indicate that regular expressions can be used with 'comm'. The task is to be able to compare file1 to file2 using a regular expression as a criterion for comparison, such as: *cd.xyz Then create a new file 'file3' that contains only those lines that satisfy the regular expression, but must contain the same format style as in file1. Any help please? Thanks in advance.
