I'm trying to give the following command:echo hi | xclip -selection cThis doesn't work?  It has worked in the past, but never consistently.  I also triedecho hi | xclip -selection primaryecho hi | xclip -selection clipboardetc....xclip is installed (I'm pretty familiar with Linux :-) ) and there is no output, it just moves onto the next line and my clipboard contents do not change.  Here is my linux version:[1450] cgeorge@uaf-7 $ cat /proc/versionLinux version 2.6.18-371.1.2.el5 (mockbuild@builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-54)) #1 SMP Tue Oct 22 12:51:53 EDT 2013
