The ana utility he has just written creates anagrams out of a phrase provided on the command line. Let’s take a look at them: ls -l ana Words.db He already created the database file that ana works with, Words.db. He has written the program, compiled it, and produced a binary called ana. Our fictional programmer’s working directory is ~/work. Our programmer has decided that the permissions must be set to:
#Mac os x terminal copy same timestamp not owner install#
The install command uses the same numeric representation for permissions as chmod does. Other users will have read and execute permissions also. Members of the geek group will have read and execute permissions. Until it is ready for release it will be tested in a directory called ~/test/ana. You’ll need to substitute the filenames and directory paths in our example for the files and paths you’re using on your computer when you use install. After testing, it must be copied to /usr/local/bin to make it available for all users of the Linux system. It consists of an executable binary file and a database.
An ExampleĪ programmer is working on just such a new utility, called ana. Finally, when your new utility is ready to be deployed, you can use install to copy it with the correct permissions to its final working location. The install command does all the heavy lifting for you. The test directory might need to be created, and you need to set the correct permissions and ownership for the files.īecause development is an iterative activity, you can end up doing this sequence of actions many, many times. To do that you need to copy the new program files to a test directory. You’ll need to do testing outside of the development environment. Let’s say you’re programming a new utility.
#Mac os x terminal copy same timestamp not owner software#
One scenario where install comes into its own is software development. It’s useful, but only for certain situations. The install command probably won’t be used every day.
