![]() ![]() If all you want is the IP of the up and outbound interface, this works. Which terminal command to get just IP address and nothing else Ask Question Asked 11 years, 6 months ago Modified 21 days ago Viewed 278k times 178 I'm trying to use just the IP address (inet) as a parameter in a script I wrote. It’s very useful in situations where we have to search through large access log files. #define AF_INET 2 /* Internet IP Protocol */ The Linux grep command is one of the most powerful utilities for searching a specific string of characters in a file or files. The numbers used to index protocols are from /usr/include/linux/socket.h (in Linux). netifaces.AF_INET, and whose values are a list of addresses in\nthat family that are attached to the network interface.' 'Obtain information about the specified network interface.\n\nReturns a dict whose keys are equal to the address family constants,\ne.g. 6.Ip addr | grep 'state UP' -A2 | tail -n1 | awk ' The first column is usually an IP address in most access log files. Let’s look at how we can use the awk command to extract all the IP addresses from the sample.log file: $ awk 'match($0, /(25|2|?)\.(25|2|?)\.(25|2|?)/) ' sample.log Moreover, we can define an action to perform whenever a match is found. Once done, you can successfully ping the hostname of the Linux machine. Be sure to update the /etc/hosts file on every Linux system that you intend to connect to the system on the same local network. It lets us write small but effective programs as statements that define text patterns to search for. This entry includes the host’s IP address and the hostname as shown. ![]() The awk command is a Linux utility to manipulate data and generate reports based on the data. We’re passing the -c option to the uniq command to get the total count of individual IP addresses. It also filters the list so it’ll only print unique IP addresses and their respective counts: $ grep -Eo '(25|2|?)\.(25|2|?)\.(25|2|?)\.(25|2|?)' sample.log | uniq -c | sort This counts and sorts the records in ascending order. We can push things further and pipe the results to the uniq and sort commands. I try to keep the content is accurate and up-to-date. I create all the content myself, with no help from AI or ML. The basic syntax is as follows: nixCraft: Privacy First, Reader Supported nixCraft is a one-person operation. We’re using the -E option to interpret the patterns as extended regular expressions (EREs) and the -o option to trim the results and only print the matched part. Using grep to get ip address - Unix
