i can generate 2 timestamps so: date +"%s" -d "$(curl -s --head http://google.com | grep ^date: | sed 's/date: //g')" // result: 1417800327 date +"%s" // result: 1417800325 how can subtract them 1 line? echo "$((1417800327-1417800325))" // result: 2 but want closer to: echo "$(( (date +"%s" -d "$(curl -s --head http://google.com | grep ^date: | sed 's/date: //g')") - (date +"%s")))" try doing : lang=c echo $(( $(date +%s) - $(date -d "$(curl -s --head http://google.com 2>&1 | awk -f'date: ' '/^date:/{print $2}')" +%s) )) or splitted multi-lines readability : lang=c echo $(( $(date +%s) - $( date -d "$(curl -s --head http://google.com | awk -f'date: ' '/^date:/{print $2}' )" +%s) ))

question: should avoid using <br/> break lines in favor of wrapping content in <p></p> ? when ok use <br/> (if ever)? they both work fine in call typical desktop browsers, 1 or other work better accessibility features , mobile devices? what current recommended best practice?

so, lets have function this (function($){ $.fn.test = function(opts){ var _object = $(this), _opts = $.extend({}, $.fn.test.defaults, opts), _callback = _opts.objects[1].callback /* code here */ _callback() /* calling callback */ } $.fn.test.defaults = { /* not important */ } }) that's how initialise function $('.element').test({ option: 0, /* not important */ variable: 1, /* not important */ objects: [ { "object" : ".element2", "callback" : false }, { "object" : ".element3", /* object № 2 */ "callback" : function(){ /* >>> {this part} <<< */ console.log (this) } }, ] so on {this part} returns data of object №2, callback function run on _object element $.fn.test output data of $('.element') . c...
