Re: [CentOS] bash - safely pass untrusted strings?

On Tue, Feb 26, 2008 at 04:33:30PM -0600, Les Mikesell alleged:

Does anyone have a quick reference to the order of operations as the shell parses a command line (variable parsing,i/o redirection, wildcard and variable expansion, splitting on IFS, quote removal, command substitution etc.)? That's really the first thing you need to know about the shell and if there is a simple description it must be buried in the middle of some obscure manual.

This is from the "EXPANSION" section of the bash manpage:

The order of expansions is: brace expansion, tilde expansion, parameter, variable and arithmetic expansion and command substitution (done in a left-to-right fashion), word splitting, and pathname expansion.
