Top Forums UNIX for Dummies Questions & Answers how to change the tab size in vi? Post 19835 by LivinFree on Wednesday 17th of April 2002 05:29:44 AM

Very close.
ex is a line-editor much like ed, but with some better features.
vi was built "on top" of ex - some versions of vi allow you toggle between ex-mode and vi-mode.
An *rc file typically means "run commands", and is sourced (to relate it to a shell function) rather than executed.
So .exrc is the "run commands" config file for ex, that vi reads as well, since vi is dependant on ex. Many of the new incarnations actually incorporate ex and vi in the same executable with hardlinks to each other.

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences exist compared to the "URI" class interface: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs. o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path: same as ($uri->abs_path || "/") o $url->netloc: same as $uri->authority o $url->epath, $url->equery: same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters) o $url->params and $url->eparams methods o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag: same as $uri->fragment o $url->keywords: same as $uri->query_keywords o $url->localpath and friends map to $uri->file. o $url->address and $url->encoded822addr: same as $uri->to for mailto URI o $url->groupart method for news URI o $url->article: same as $uri->message SEE ALSO
