( #3333=superdoc: print w/replies, xml ) Need Help??

Our Computers Room is too hot today...

Similar problem as before, but with an important variation: I had to match just a small range of lines in the output of a command. This one-liner now runs on a Sun Ultra-Enterprise host running Solaris 8, and a monitoring software reads and reports the temperatures of the system boards.

/usr/platform/sun4u/sbin/prtdiag -v | perl -ne 'BEGIN { print "TABLE temperature\nSTART_SAMPLE_PERIOD\n" } ; END { print join ("NEXT_SAMPLE\n",@samples),"END_SAMPLE_PERIOD\nEND_TABLE\nSLEEP\n" } ; if (/^System Temperatures/../^$/) { next unless /^(CLK|\s*\d+)/ ; ($b,$t) = (split)[0,2] ; push @samples,"board=$b\ntemp=$t\n" }'

Have fun

Ciao!

In theory, there is no difference between theory and practice. In practice, there is.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
