ISSUE: Screen shot is a necessary part of developers life. So you must know how to take screen shot in any OS. When taking screen shot by "Prnt Scrn" button centos give error like - There was an error running "gnome-screenshot": Failed to execute child process "gnome-screenshot" (No such file or directory). Fix: This issue arise due to gnome util's unavailability. So just install it by yum as a root - yum install gnome-utils and enjoy screening.
