Human Readable ls and df commands

Simple but useful to know...

To get a ls (file list) or df (disk free) to show in K,M or G instead of *huge* numbers of bytes without commas, use the -h flag.

ls -lh
df -h

Get all files in ftp server directory using WGET

It's a PITA to recursively get all files in a directory using ftp. Instead use wget.

wget -r

explode() function for Actionscript

A simple version of the explode() function in PHP. It takes a string and splits it up into an array by splitting it at whatever character (or characters) you specify. For example, reading in a tab delimited text file. Will split it into lines by splitting on returns ("\r"). Then split up the lines by splitting on tabs ("\t").

Attribution: I didn't write this myself, I found it in a comment on one of the Actionscript on-line documentation pages.

function explode(separator:String, string:String) {

        var list = new Array();

        if (separator == null) return false;
        if (string == null) return false;

        var currentStringPosition = 0;
        while (currentStringPosition<string.length) {
                var nextIndex = string.indexOf(separator, currentStringPosition);
                if (nextIndex == -1) break;
                var word = string.slice(currentStringPosition, nextIndex);
                currentStringPosition = nextIndex+1;
        if (list.length<1) {
        } else {
                list.push(string.slice(currentStringPosition, string.length));
        return list;

print_r() for Actionscript

Here's a cheap little function to mimic the print_r() function from PHP in Actionscript. It's designed to work on most any array and will handle nested arrays through recursion.
// recursive function to print out the contents of an array similar to the PHP print_r() funciton
function print_a( obj, indent ) {
        if (indent == null) indent = "";
        var out = "";
        for ( item in obj ) {
                if (typeof( obj[item] ) == "object" )
                        out += indent+"[" + item + "] => Object\n";
                        out += indent+"[" + item + "] => " + obj[item]+"\n";
                out += print_a( obj[item], indent+"   " );
        return out;
// example call
trace( print_a( example_array ) );

Collapse Whitespace function for Actionscript

This function will strip out all tabs and return characters. It will also collapse all runs of multiple spaces down to one. It will also remove a leading and trailing spaces. It is similar to the php_strip_whiespace() function in PHP.

function collapseWhiteSpace( theString ) {
        theString =  theString.split("\r").join("");
        theString =  theString.split("\t").join("");
        while ( theString.indexOf("  " ) != -1 ) {
                theString= theString.split("  ").join(" ");
        if (theString.substr(0,1) == " ") {
                theString = theString.substr( 1 );
        if (theString.substr( theString.length-1, 1 ) == " ") {
                theString = theString.substr( 0, theString.length - 1 );
        return( theString );

Parse out body content from html file in PHP

Parse out the body content of an html file. If no tags found, assume whole file is the content to be used.

        $body_content = join( "", file( $file_to_be_read ) );
        if (eregi( "(.*)", $t, $regs ) ) {
                $body_content = $regs[0];

Reverse DNS from command line

Quick and easy way to look up a domain name given an IP address.

dig -x

Retreiving a Flash movie's domain name

Use the LocalConnection object to get the domain name of the server where the Flash movie is located.

var localDomainLC:LocalConneciton = new LocalConnection();
myDomainName = localDomainLC.domain();
trace( "My domain is " + myDomainName );

This will print out something like this:

My domain is

Search for open files that won't allow you to unmount a server volume

lsof | grep "Office Server"

Lists out all open files on a given volume ("Office Server" in this case.) Good to find those peskey open files that won't let you eject a mounted network volume.
