A simple php program that converts all big numbers from its standard in, into more human readable text.
I often use it to find big directories & files, typical usage:
du -bx /var/log | sort -n | tail | big2si
Or track rsync syncing a large set of files:
watch -d 'du -bx rsync_target | sort -n | tail -30 | big2si'
#!/usr/bin/php
<?php
function si($v,$dec=1) {
$six=array('K','M','G','T','P','E','Are you nuts?');
$sis='';
while ($v>800) {
$v=$v/1024.0;
$sis=array_shift($six);
}
return (round($v*pow(10,$dec))/pow(10.0,$dec)).$sis;
}
function sicb($m) {
return si($m[1],2);
}
$fp = fopen("php://stdin", "r") or die("can't read stdin");
while (!feof($fp)) {
$line = fgets($fp);
$line = preg_replace_callback('/([0-9]{3,})/','sicb',$line);
echo "$line";
}
