Michael Jackson dies in LA hospital Michael Jackson, the sensationally gifted child star who rose to become the “King of Pop” and the biggest celebrity in the world only to fall from his throne in a freakish series of scandals, died Thursday, a person with knowledge of the situation told The Associated Press. He was 50. The person said Jackson died in a Los Angeles hospital. The person was not authorized to speak publicly and requested anonymity. The circumstances of his death were not immediately clear. Jackson was not breathing when Los Angeles Fire Department paramedics responded to a call at his Los Angeles home about 12:30 p.m., Capt. Steve Ruda told the Los Angeles Times. The paramedics performed CPR and took him to UCLA Medical Center, Ruda told the newspaper. Jackson’s death brought a tragic end to a long, bizarre, sometimes farcical decline from his peak in the 1980s, when he was popular music’s premier all-around performer, a uniter of black and white .....

Brazilian scientists have identified a new strain of the H1N1 virus after examining samples from a patient in Sao Paulo, their institute The variant has been called A/Sao Paulo/1454/H1N1 by the Adolfo Lutz Bacteriological Institute, which compared it with samples of the A(H1N1) swine flu from California. The genetic sequence of the new sub-type of the H1N1 virus was isolated by a virology team lead by one of its researchers, Terezinha Maria de Paiva, the institute said in a statement. The mutation comprised of alterations in the Hemagglutinin protein which allows the virus to infect new hosts, it said. It was not yet known whether the new strain was more aggressive than the current A(H1N1) virus which has been declared pandemic by the World Health Organization. The genetic make-up of the H1N1 virus and its subvariants are important for scientists.

Question: I know #!/bin/bash is shebang line. But, I noticed a few shell script shebang line ends with a single dash ( #!/bin/bash - ) or double dash ( #!/bin/bash -- ). Can you explains me purpose of such shebang line? Answer: A - or -- signals the end of options and disables further option processing i.e. bash will not accept any of its option. Any arguments after the -- are treated as filenames and arguments. An argument of - is equivalent to --. This is done to improve script security. Some user may perform setuid based script root spoofing.

EPEL provide lots of packages for CentOS / RHEL, It is not part of RedHat or CentOS but is designed to work with these major distributions. Please note that EPEL only provides free and open source software unencumbered by patents or any legal issues. In short you will not find mp3, dvd and music / media player under EPEL.
