Of course that benefit comes with some costs, but this isn't the place for that debate–there are plenty of other places for that.Īssuming you don't want to or can't go the App Store route, both PKG and DMG are common ways to distribute a program. And, believe it or not, normal people have a lot of trouble with the concept of installing a program. This has the benefit of making application installation transparent to the normal user.

This tool allows you to run your editor in the middle of a unix pipeline and edit the data that is being piped between programs (once again, check the $EDITOR environment variable for your text editor of choice).Apple is very clearly making the "standard" to be downloading a program from the App Store. Alternatively, a list of files can be specified on the command line. Note that if “-“ is specified as the directory to edit, it reads a list of filenames from stdin and displays those for editing. You can also switch pairs of numbers to swap filenames.

Delete lines to remove files from the directory, or edit filenames to rename files. These numbers are how vidir keeps track of what items are changed. When editing a directory, each item in the directory will appear on its own numbered line. If no directory is specified, the current directory is edited. This tool allows editing of the contents of a directory in a text editor (check the $EDITOR environment variable, because it will be used for the text editor of your choice). In addition to the regular strftime conversion specifications, %.S and %.s are like %S and %s, but provide sub-second resolution (i.e., “30.00001” and “1301682593.00001”). The optional format parameter controls how the timestamp is formatted, as used by the C function strftime.

Unlike ifconfig or ip, ifdata has simple to parse output that is designed to be easily used by a shell script. This tool can be used to check for the existence of a network interface, or to get information about the interface, such as its IP address, all statistics on input and output, number of packets, bytes, errors, drops, incoming and outgoing bit rate, etc. If you do a lot UNIX programming you know what I am taking about. This is a most valuable tool and a lot better than reading the system header files to figure out the meaning of a particular errno code.

Among the UNIX utilities available, there is one package that includes some awesome utilities that makes our life’s a lot easier: the moreutils package. Most UNIX professionals know about the GNU core utilities, from the “used-everyday” ls, cp, ln, rm, touch, tail, wc, etc., to the “not-so-used” shell commands such as tsort, tac, factor, or seq.
