PROBLEM: An element ID that looked like this would fail to match: service = east node = db1-demo.thedomain.com
< div style = "width: 50px; height: 50px; background: #00aa00; color: #000;" id = "Div-node-notes-east-db1-demo.thedomain.com" > Content to hide and show here < / div >
< a href = "#" onclick = "jQuery('#Div-node-notes-'+service+'-'+node.toggle();return false;" > Toggle Div < / a >
SOLUTION: Rig any special characters in the complex hostname (:.[],-@) with a backslash in front of them to ensure proper matching:
<script>
var G = { } ;
G . cleanid = function ( myid ) {
return myid . replace ( /(:|\.|\[|\]|,|=|@)/g , "\\$1" ) ;
}
</script>
< div style = "width: 50px; height: 50px; background: #00aa00; color: #000;" id = "Div-node-notes-east-db1-demo.thedomain.com" > Content to hide and show here < / div >
< a href = "#" onclick = "jQuery('#Div-node-notes-'+service+'-'+G.cleanid(node).toggle();return false;" > Toggle Div < / a >

## to add a single backslash in front of whatever char was matched
my $ password = q #abc'A1r%Fgt&jh[-#;
$ password = ~ s / ( [ '])/\\$1/g;
print qq#' $ password '\n#;
' abc \ 'A1r % Fgt & jh [ - '
## to double whatever char was matched
my $ password = q #abc'A1r%Fgt&jh[-#;
$ password = ~ s / ( [ '])/$1$1/g;
print qq#' $ password '\n#;
' abc '' A1r % Fgt & jh [ - '
## to convert ‘ to ‘\” for shell execution
my $ password = q #abc'A1r%Fgt&jh[-#;
$ passwordShell = ~ s / ( [ '])/$1\\$1$1/g;

' abc '\'' A1r % Fgt & jh [ - '

Using PERL, we can easily do a search and replace across multiple files. perl -pi -w -e ‘s/SEARCH_FOR/REPLACE_WITH/g;’ FILE_LIST The following example will replace all occurrences of “hello” with “goodbye” inside files ending with .txt:
