i, -ignore-nonprinting consider only printable characters g, -general-numeric-sort compare according to general numerical value f, -ignore-case fold lower case to upper case characters d, -dictionary-order consider only blanks and alphanumeric characters b, -ignore-leading-blanks ignore leading blanks Mandatory arguments to long options are mandatory for short options too. Write sorted concatenation of all FILE(s) to standard output. The output from the sort -help command is pretty short, so I'll include it here: Which creates a new file named files.sorted, which contains the new, sorted output. To have the sorted output to another file, you'd run a command like this: It's very important to note that this command does not sort the actual file, it just displays the sorted output on your terminal. ![]() Here's what a file named files looks like before I sort it:Īnd here's the output when I run a simple sort command against it: You can also sort the contents of a file with the Linux sort command. That shows the longest files at the bottom of the output. I just used this command to sort the output of a word count command: $ ps auxw | sort -rnk2 Sorting `wc` output You can also reverse that sort with the -r option: Or you can sort numerically by column two (the PID field): You can just sort alphabetically by the first column (username): ( ls now has a sort option I just showed this as an example.) Sorting output of the ‘ps’ commandįrom time to time you'll want to sort the output of the Linux ps command, and again here, the sort command can be your friend. Like other Unix commands, these sort command options can be combined and shortened, like this: The -n in my example means "sort numerically", and the -k5 option means to key off of column five. rw-r-r- 1 al al 4431 1 al al 9689 CAPContent2.rga copy rw-r-r- 1 al al 1425 CreateAPodcast.lofĭrwxr-xr-x 50 al al 1700 1 al al 2716 CreateAPodcast.tex This results in the following ls command sorted output, which as you can see, is a directory listing, sorted by filesize (the 5th column): For instance, here's an example where I sort the output of the ls -al command: You can use the Linux sort command to sort all kinds of output from other commands. This article shares several examples of the Linux sort command. This reignited use of the language and "VB" remains a major programming language in the forms of VBA and VB.NET.Linux sort command FAQ: Can you share some examples of the Unix/Linux sort command?Īs its name implies, the Unix/Linux sort command lets you sort text information. In 1991, Microsoft released Visual Basic, combining an updated version of BASIC with a visual forms builder. These PCs almost always had a BASIC interpreter installed by default, often in the machine's firmware or sometimes on a ROM cartridge.īASIC declined in popularity in the 1990s, as more powerful microcomputers came to market and programming languages with advanced features (such as Pascal and C) became tenable on such computers. ![]() BASIC was available for almost any system of the era, and became the de facto programming language for home computer systems that emerged in the late 1970s. Due to the tiny main memory available on these machines, often 4 KB, a variety of Tiny BASIC dialects was also created. The emergence of microcomputers in the mid-1970s led to the development of multiple BASIC dialects, including Microsoft BASIC in 1975. Many early video games trace their history to one of these versions of BASIC. ![]() Hewlett-Packard produced an entire computer line for this method of operation, introducing the HP2000 series in the late 1960s and continuing sales into the 1980s. This general model became very popular on minicomputer systems like the PDP-11 and Data General Nova in the late 1960s and early 1970s. In addition to the program language, Kemeny and Kurtz developed the Dartmouth Time Sharing System (DTSS), which allowed multiple users to edit and run BASIC programs simultaneously on remote terminals.
