Concerning free software, programming, and whatever else I find interesting. Also the blog for my Web site, frigidcode.com.
Two handy manual pages from the LPM
One of the downsides to living in the age of the search engine is that many of us do not know how to find documentation in the place it is supposed to be. Sometimes, we waste much time and bandwidth trying to find information that is available locally. Two such examples from my own experience are listed below:
1) OPERATOR(7). I can't count the number of times I have done a Google search trying to remember if a '&&' had higher precedence than a '||', or some similar question. The man operator command will give you a list of all the C operators, including their precedence and their associativity.
2) ASCII(7). While asciitable.com will give you a lot more snazzy banner ads, for speed you still can't beat a call to man ascii. This manual page will give you each character from the standard set along with hex, decimal, and octal representations. It will also give you compact indexing tables, a brief history of the ASCII standard, and cross references to the manual pages for the various ISO character sets.
