Bash read file to an array based on two delimiters -

-
i have file need parse array want brief portion of each line , first 84 lines. line maybe: >mt gi... and want mt entered array. other times might this: >gl000207.1 dn... and need gl000207.1 i thinking might able set 2 delimiters (one being '>' , other being ' ' whitespace) not sure how go it. have read other peoples posts internal field separator not sure of how work. think perhaps might work though? desiredarray=$(echo file.whatever | tr ">" " ") x in $desiredarray echo > $x done any suggestions? how about: head -84 <file> | awk '{print $1}' | tr -d '>' head takes first lines of file, awk strips off first space , after it, , tr gets rid of '>'.

html - two div boxes [1st float, 2nd clear], margin on 2nd doesn't seem to push off first -

-
in code below have 2 div boxes. first float:left, second has clear:left sits below first. question why margin-top:20px not push off first div? <head> <style> div { width:100px; height:100px; background-color:green; } #box1 { float:left; } #box2 { background-color:red; clear:left; margin-top:20px; } </style> </head> <body> <div id="box1"></div> <div id="box2"></div> </body> yeah, it's confusing. read css spec on collapsing margins . specifically, "if top , bottom margins of element clearance adjoining, margins collapse adjoining margins of following siblings resulting margin not collapse bottom margin of parent block." to effect you're looking need apply margin element doesn't have clearance, in case first div, this: http://jsfiddle.net/6bfyu/

've noticed when browsing through jsf application urls 1 sees @ browser (when ?faces-redirect=true not used) ones of "previous" "page". meta-nb. behind firewall , plagued "so requires external javascript domain" issue apologize absence of formatting. provide feedback on answers in few hours, when can access domain. page-to-page navigation should not performed using post @ all. should using normal <h:link> or <h:button> instead of <h:commandlink> or <h:commandbutton...
