If you use Apple’s Disk Utility application to Repair Permissions on your Mac OS X system AND you have CommuniGate Pro installed, you’ll end up messing up CGPro’s files such that the following won’t work:
echo "Hello" | mail -s "Hi There" [email protected]
The affected files from the Disk Utility report are:
Group differs on ./private/etc/mail/submit.cf,
should be 7, group is 0
Owner and group corrected on ./private/etc/mail/submit.cf
Permissions corrected on ./private/etc/mail/submit.cf
Group differs on ./usr/bin/mail, should be 0, group is 6
Permissions differ on ./usr/bin/mail,
should be -r-xr-xr-x , they are -r-xr-sr-x
Owner and group corrected on ./usr/bin/mail
Permissions corrected on ./usr/bin/mail
To fix things, do:
sudo chown root:wheel /private/etc/mail/submit.cf
sudo chown root:mail /usr/sbin/CommuniGatePro/mail
sudo chmod 2555 /usr/sbin/CommuniGatePro/mail
sudo chown root:mail /usr/sbin/CommuniGatePro/sendmail
sudo chmod 2555 /usr/sbin/CommuniGatePro/sendmail
Just a quick note to mention that when iTunes 4 asks if you want to “Replace Existing” songs when re-encoding, what it really means is “Move Existing to Trash”. As I’m re-encoding my entire CD collection to AAC, I just happened to notice in the info bar of a Finder window that my disk had only a few hundred megabytes of free space left. The trash was full (several gigabytes) of my old MP3 that had been moved there by iTunes 4!
I’m currently reading through Mac OS X Hacks, by Rael Dornfest. It’s a good read, with some interesting OS X tricks and tips (like controlling iTunes via Perl). Finally some books are starting to appear for the Mac non-beginner. (Thank you O’Reilly & Associates!) I’ve also added his weblog to my NetNewsWire “7+/-2” list.
I guess it was about a year ago, Apple Computer introduced the combination of an MP3 player (the iPod) and companion software (iTunes) for the Mac OS X. The tight integration of an innovative device like the iPod and easy-to-use software like iTunes made Apple (and its users) the envy of the music-loving Windows world. While users of other MP3 players could carry around a few CDs worth of MP3, iPod users could tote around thousands of songs in the ultracool device.
While others continue in their pursuit to copy the iPod and iTunes, Apple yesterday took a huge leap forward, through the introduction of iTunes version 4, and launching its own Music Service. iTunes users can now, within the same easy-to-use interface, access a library of more than 200,000 songs, purchasing albums for an average of $10 or, probably more importantly, individual songs for 0.99 cents. Every song in the service has a 30 second immediate preview, to allow listen-before-you-buy.
Purchasing couldn’t be easier. Once you’ve setup an account, just click the buy button on any song or album, confirm the purchase, and the song is immediately downloaded and stored in your songs library. To be honest, I’m personally quite worried about such convenience, being a music lover and an impulse buyer! Having tried the service out this morning, I’ve already purchased four songs, and can’t imagine an easier or more convenient way to shop for music.
