Operating Systems Linux Debian Using sed with bash variables Post 302945874 by RudiC on Thursday 4th of June 2015 05:32:36 AM
Please use code tags as required by forum rules!

The single quotes prevent the variable from expansion, so the literal name is inserted. Try using double quotes instead, and don't escape the $ with the \ . Some seds insist on a line break before the insertion text.

Text::Typography - Markup ASCII text with correct typography for HTML SYNOPSIS
use Text::Typography qw(typography); print typography($text); DESCRIPTION
This module is a thin wrapper for John Gruber's SmartyPants plugin for various CMSs. SmartyPants is a web publishing utility that translates plain ASCII punctuation characters into "smart" typographic punctuation HTML enti- ties. SmartyPants can perform the following transformations: o Straight quotes ( " and ' ) into "curly" quote HTML entities o Backticks-style quotes (``like this'') into "curly" quote HTML entities o Dashes ("--" and "---") into en- and em-dash entities o Three consecutive dots ("...") into an ellipsis entity SmartyPants does not modify characters within "<pre>", "<code>", "<kbd>", "<script>", or "<math>" tag blocks. Typically, these tags are used to display text where smart quotes and other "smart punctuation" would not be appropriate, such as source code or example markup. typography($text[, $attributes]) Returns a string marked up with the proper HTML entities for proper typography. For fine grain control over what gets converted, use the $attributes option. The default value is 3. The following numeric values set a group of options: 0 : do nothing 1 : set all 2 : set all, using old school en- and em- dash shortcuts (-- and ---) 3 : set all, using inverted old school en- and em- dash shortcuts (--- and --) For even finer control, specify a string of one or more of the following characters: q : quotes b : backtick quotes (``double'' only) B : backtick quotes (``double'' and `single') d : dashes D : old school dashes i : inverted old school dashes e : ellipses w : convert &quot; entities to " for Dreamweaver users Backslash Escapes If you need to use literal straight quotes (or plain hyphens and periods), SmartyPants accepts the following backslash escape sequences to force non-smart punctuation. It does so by transforming the escape sequence into a decimal-encoded HTML entity: Escape Value Character ------ ----- --------- \ &#92; " &#34; " ' &#39; ' . &#46; . - &#45; - ` &#96; ` This is useful, for example, when you want to use straight quotes as foot and inch marks: 6'2" tall; a 17" iMac. Algorithmic Shortcomings One situation in which quotes will get curled the wrong way is when apostrophes are used at the start of leading contractions. For example: 'Twas the night before Christmas. In the case above, SmartyPants will turn the apostrophe into an opening single-quote, when in fact it should be a closing one. I don't think this problem can be solved in the general case -- every word processor I've tried gets this wrong as well. In such cases, it's best to use the proper HTML entity for closing single-quotes ("&#8217;") by hand. AUTHOR
