awk in Mac OS X
By: Strauss K in macos Tutorials on 2011-02-03
awk is a powerful command-line tool for text processing and data manipulation in Unix and Unix-like systems, including macOS. It allows you to search for specific patterns and perform various operations on the input data.
Here are some basic examples of using awk in Mac OS X:
Print the contents of a file:
awk '{print}' file.txt
Print only the first column of a file (using space as the delimiter):
awk '{print $1}' file.txt
Print only lines containing a specific pattern:
awk '/pattern/{print}' file.txt
Print the number of lines in a file:
awk 'END {print NR}' file.txt
Calculate the sum of the values in the second column of a file:
awk '{sum += $2} END {print sum}' file.txt
These are just a few examples of what you can do with awk. It's a very powerful tool, and there are many more advanced features and options available.
