Find all PowerPC applications on OS X

This finds all the PowerPC apps recognized by OS X.

A better version is:

s[$i].=$al[$j]; $i++ if ($al[$j]) =~ /^\s\s\s\s\S.*:$/; $j++} while($k

apps[$k++]; if (/Kind: PowerPC/s) {print; $p++;}} print "$i applications, $p P

owerPC applications\n\n"'

but that is more than 255 characters...

Download entire commandlinefu archive to single file

This is an extension of a previous command by satyavvd on 2009-07-23 12:04:02, but this one grabs the whole archive. Hard coded numbers in previous script capped number of commands that could be fetched. This one grabs them all regardless of how big the archive gets.

Show changed files, ignoring permission, date and whitespace changes

Only shows files with actual changes to text (excluding whitespace). Useful if you've messed up permissions or transferred in files from windows or something like that, so that you can get a list of changed files, and clean up the rest.

show the real times iso of epochs for a given column

When you have one of those (log)files that only has epoch for time (since no one will ever look at them as a date) this is a way to get the human readable date/time and do further inspection.

Fetches the IPs and ONLY the IPs from ifconfig. Simplest, shortest, cleanest.

Perl is too good to be true...

Read just the IP address of a device

Found this useful for scripts where I needed to work with the machine's IP. If $DEVICE is not specified, this will return all IPs on the machine. If $DEVICE is set to a network adapter, it will return just that adapter's IP.
