Htop 2.0: Linux Process Monitoring<\/p>\n<\/div>\n

Htop<\/strong>\u00a0is an interactive real time process monitoring application for Linux\/Unix like systems and also a handy alternative to\u00a0top command<\/a>, which is default process monitoring tool that comes with pre-installed on all Linux operating systems.<\/p>\n

Htop<\/strong>\u00a0has numerous other user-friendly features, which are not available under top command and they are:<\/p>\n

    \n
  1. In htop you can scroll vertically to view the full process list, and scroll horizontally to view the full command lines.<\/li>\n
  2. It starts very quickly as compared top, because it doesn\u2019t wait to fetch data during startup.<\/li>\n
  3. In htop you can kill more than one processes at once without inserting their PIDs.<\/li>\n
  4. In htop you no longer needed to enter process number or priority value to re-nice a process.<\/li>\n
  5. Press \u201ce\u201d to print the set of environment variables for a process.<\/li>\n
  6. Use mouse to select list items.<\/li>\n<\/ol>\n

    To install\u00a0Htop<\/strong>\u00a0on\u00a0RHEL 7\/6\/5<\/strong>\u00a0and\u00a0CentOS 7\/6\/5<\/strong>, your system must have\u00a0EPEL<\/strong>\u00a0repository installed and enabled, to do so run the following commands on your respective distributions to install and enable it for your system architecture (32bit<\/strong>\u00a0or\u00a064bit<\/strong>).<\/p>\n

    On RHEL\/CentOS \u2013 32-bit OS<\/h4>\n
    -------------- For RHEL\/CentOS 6 --------------<\/strong>\r\n# wget http:\/\/download.fedoraproject.org\/pub\/epel\/6\/i386\/epel-release-6-8.noarch.rpm\r\n# rpm -ihv epel-release-6-8.noarch.rpm\r\n\r\n-------------- For RHEL\/CentOS 5 --------------<\/strong>\r\n# wget http:\/\/download.fedoraproject.org\/pub\/epel\/5\/i386\/epel-release-5-4.noarch.rpm\r\n# rpm -ihv epel-release-5-4.noarch.rpm\r\n<\/pre>\n
    On RHEL\/CentOS \u2013 64-bit OS<\/h4>\n
    -------------- For RHEL\/CentOS 7 --------------<\/strong>\r\n# wget dl.fedoraproject.org\/pub\/epel\/7\/x86_64\/Packages\/e\/epel-release-7-11.noarch.rpm\r\n# rpm -ihv epel-release-7-11.noarch.rpm \r\n\r\n-------------- For RHEL\/CentOS 6 --------------<\/strong>\r\n# wget http:\/\/download.fedoraproject.org\/pub\/epel\/6\/x86_64\/epel-release-6-8.noarch.rpm\r\n# rpm -ihv epel-release-6-8.noarch.rpm\r\n\r\n-------------- For RHEL\/CentOS 5 --------------<\/strong>\r\n# wget http:\/\/download.fedoraproject.org\/pub\/epel\/5\/x86_64\/epel-release-5-4.noarch.rpm\r\n# rpm -ihv epel-release-5-4.noarch.rpm<\/pre>\n
