Putting It Together All of the Unix syntax and vocabulary presented in this chapter is all well and good and it ll give you the rosy glow of having mastered something new. But it still doesn t entirely explain why Unix gives programmers sweaty palms and dilated pupils. The real power of Unix comes down the road when you start stringing these commands together. Suppose for example you want to round up all the TIFF image files related to your Yosemite project scale them to a common size convert them to JPEG files and copy them to an FTP site. How would you go about it You could of course use Spotlight to search for all TIFF files that have Yosemite in their names. But what if your images were named otherwise but kept in folders with Yosemite in their names You would have to find those folders first and then the TIFF files within them. You could perform the next step scaling and converting the image either manually or by a preprogrammed script or Automator workflow using a program like Photoshop or even iPhoto. Once the images were all done you d need to collect them and then use your favorite FTP program to upload them to the server. If you ve mastered Unix though you could shave 12 minutes off of your workday just by changing to an empty working directory in this example - Stage and typing this as one long line find - -type f -ipath yosemite tif -printo xargs -0 sips -Z 250 -s format jpeg --out - Stage ftp -u ftp Incoming Even after almost 50 pages of Unix basics that mass of commands probably looks a tad intimidating. And indeed if you ve never programmed before even the following breakdown may make your eyes glaze over. Nevertheless pieces of it should now look familiar find - -type f-ipath yosemite tif -printo . This segment searches your Home directory - for files -type f whose pathnames -ipath meaning capitalization doesn t matter contain the word Yosemite and end in tif.
