jpayne@69: Description:  Counts the number of lines shared between sets of files.
jpayne@69: One output file will be printed for each input file.  For example,
jpayne@69: an output file for a file in the 'in1' set will contain one line per
jpayne@69: file in the 'in2' set, indicating how many lines are shared.
jpayne@69: 
jpayne@69: Usage:  countsharedlines.sh in1=<file,file...> in2=<file,file...>
jpayne@69: 
jpayne@69: Parameters:
jpayne@69: include=f       Set to 'true' to include the filtered names rather than excluding them.
jpayne@69: prefix=f        Allow matching of only the line's prefix (all characters up to first whitespace).
jpayne@69: case=t          (casesensitive) Match case also.
jpayne@69: ow=t            (overwrite) Overwrites files that already exist.
jpayne@69: app=f           (append) Append to files that already exist.
jpayne@69: zl=4            (ziplevel) Set compression level, 1 (low) to 9 (max).
jpayne@69: 
jpayne@69: Java Parameters:
jpayne@69: -Xmx            This will set Java's memory usage, overriding autodetection.
jpayne@69:                 -Xmx20g will specify 20 gigs of RAM, and -Xmx200m will specify 200 megs.
jpayne@69:                     The max is typically 85% of physical memory.
jpayne@69: -eoom           This flag will cause the process to exit if an out-of-memory
jpayne@69:                 exception occurs.  Requires Java 8u92+.
jpayne@69: -da             Disable assertions.
