top - looks better and is more useful with a rc file...

2010-05-07 1 min read Fedora Learning Linux

top is a very useful command to find out who is eating up the <a class="zem_slink freebase/en/central_processing_unit" title="Central processing unit" rel="wikipedia" href="http://en.wikipedia.org/wiki/Central_processing_unit">CPU or the memory. But sometimes the plain and simple look simply would be boring so how about some fun. Copy the below code to file : ~/.toprc

RCfile for ”top”

In this part I will create various one-liners for string and array creation. See <a href="http://www.catonmat.net/blog/perl-one-liners-explained-part-one/">part one for introduction of the series.

Famous Perl one-liners is my attempt to create “perl1line.txt” that is similar to “<a href="http://www.catonmat.net/blog/awk-one-liners-explained-part-one/">awk1line.txt” and “<a href="http://www.catonmat.net/blog/sed-one-liners-explained-part-one/">sed1line.txt” that have been so popular among Awk and Sed programmers.
