How to uninstall Mac OS X .pkg packages By SHARNINDER | Published: OCTOBER 29, 2009 Most applications on OS X are distributed using either a .DMG disk image file or a .pkg installer. Installing using a DMG is the easiest. Just drag the application from the mounted image to the Applications folder and you’re done. The .pkg installer, on the other hand, works like a traditional installer. Double click the program, go through a couple of steps using a Wizard and the application is installed. Unlike other operating systems, though, Apple doesn’t provide a simple method to uninstall applications. In the case of a DMG based install, all you have to do is drag the application from the Applications folder into the Trash and it’s gone. A pkg based installer, on the other hand, doesn’t offer any such luxuries. The user depends on the developer to provide an uninstaller for their application, which is often not the case. So, how do you uninstall applications installed using a .pkg installer ? Wel

Handle Too-Long Command Lines with xargs xargs is one of those UNIX utilities that seems pretty useless when you first hear about it -- but turns into one of the handiest tools you can have. xargs reads a group of arguments from its standard input, then runs a UNIX command with that group of arguments. It keeps reading arguments and running the command until it runs out of arguments. The shell's backquotes do the same kind of thing, but they give all the arguments to the command at once. This can give you a Too many arguments error. Here are a couple of examples: If you want to print most of the files in a large directory, put the output of ls into a file. Edit the file to leave just the filenames you want printed. Give the file to xargs ' standard input: % ls > allfiles.tmp % vi allfiles.tmp % xargs lpr <> What did that do? With lines like these in allfiles.tmp : % cat allfiles.tmp afile application ... yoyotest zapme xargs ran one or more lpr commands,

Ten OS X Command Line Utilities you might not know about The Mac OS X command line interface is home to thousands of programs that the average user doesn’t know exists. Leveraging years of hard work by the GNU foundation and others in the open source community, Apple designed a wonderful OS that doesn’t “need” any use of the command line. While using the command line in Mac OS X is not necessary for the every day operation of a Macintosh, if harnessed correctly, it can save you a lot of time, and occasionally give you a laugh. I hope you enjoy these ten OS X command line utilities! Update: There is also a Chinese version of this article available here , translated by Klaith . Thanks Klaith! 1. ssh This little gem is included in every version of Mac OS X. Originally developed as drop-in replace to the rsh/rlogin programs, ssh has become a staple of the Linux/Unix(and now Mac OS X) community. Openssh’s primary use is secure remote administration. If you wish you enable Mac OS X’s b
