For example on windows:
C:\>pmd-bin-5.2.2\bin\pmd.bat -dir c:\my\source\code -format text -R java-unusedcode,java-imports -version 1.5 -language java -debug
C:\>pmd-bin-5.2.2\bin\pmd.bat -dir c:\my\source\code -f xml -rulesets java-basic,java-design -encoding UTF-8
C:\>pmd-bin-5.2.2\bin\pmd.bat -d c:\my\source\code -rulesets java-typeresolution -auxclasspath commons-collections.jar;derby.jar
C:\>pmd-bin-5.2.2\bin\pmd.bat -d c:\my\source\code -f html -R java-typeresolution -auxclasspath file:///C:/my/classpathfile

For example on *nix:
$ pmd-bin-5.2.2/bin/run.sh pmd -dir /home/workspace/src/main/java/code -f html -rulesets java-basic,java-design
$ pmd-bin-5.2.2/bin/run.sh pmd -d ./src/main/java/code -f xslt -R java-basic,java-design -property xsltFilename=my-own.xsl

$ pmd-bin-5.2.2/bin/run.sh pmd -d ./src/main/java/code -f html -R java-typeresolution -auxclasspath commons-collections.jar:derby.jar
