Use pipeline for pipe string
//Remove all space in output
cat somefile.txt | petl_cli pipeline="r"
//Make upper case
cat somefile.txt | petl_cli pipeline="u"
//Make lower case
cat somefile.txt | petl_cli pipeline="l"
//Pipeline it
//Will make lower case first then upper case, final remove all space.
cat somefile.txt | petl_cli pipeline="lur"
