According to the OpenLMI project webpage: OpenLPI provides a common infrastructure for the management of Linux systems. Capabilities include configuration, management and monitoring of hardware, operating systems, and system services. OpenLMI includes a set of services that can be accessed both locally and remotely, multiple language bindings, standard APIs, and standard scripting interfaces. OpenLMI is a another attempt by Red Hat to provide unified management of Linux systems. This is not their first attempt to provide such functionality.

The / and ? search commands in vi search forward and backward respectively from the current line. Sometimes, however, you may wish to search forwards or backwards from a particular line number or find the nth occurrence of a regular expression (RE). The commands: :line/RE :line?RE will search forward and backward, respectively, for the RE starting from the line number line. Another useful facility in vi is the ability to find the nth occurrence of an RE starting at the current line. The commands: nth/RE nth?RE will search forward and backward, respectively, for the nth occurrence of the RE starting
It is easy to create a file consisting of all zeros in Linux using dd and the /dev/zero device. $ dd if=/dev/zero count=100 bs=1 > outfile So how do you create a file consisting of all binary ones? There is no device to create binary ones so you have to do something like the following: $ dd if=/dev/zero count=100 bs=1 | tr “00” “377” > outfile You can use xxd to see the contents of the resultant file: $ xxd -b outfile 0000000: 11111111 11111111 11111111 11111111 11111111 11111111 …… 0000006: 11111111 11111111 11111111 11111111 11111111 11111111 …… 000000c: 11111111
