    perl -v

    [download]
    Other than that the only one I use is search and replace. 
    perl -pi -e 's/somestring/otherstring/g' *.htm

    [download]

    cut, grep, xargs and find ususally do instead

    Why not just use localtime? 
    perl -le'print localtime =~ /Fri/ ? "w" : "b", "oohoo"'

    [download]
    Or: 
    perl -le'print 5 == (localtime)[6] ? "w" : "b", "oohoo"'
