English is clearly the OP's second language, and his post was pretty clear that 
he did indeed want to remove a single item from the things named in $PATH. He 
even provided example code showing exactly what he wanted to remove, and which 
demonstrated that he knew it was a colon separated string, which he was 
presenting as lines for purposes of clarity.
