Can you give me an example of how to use awk?

3 Answers

I wasn't familiar with awk.

Awk can be used to do a lot of the things Excel is used for, it is a programming language. to search for the word "Pants" on a line of a file and then print the third word, delimited by : you would do awk -F':' '$0 ~ /Pants/ {print $3}' Less

Awk is a field processor in that it is capable of extracting columns( the spreadsheet columns for instance). A typical example of awk in Linux distribution is: awk '{print $1}' spreadsheet1.txt The above prints the first column of the file spreadsheet1.txt. More complex example of awk is using regex with it. For instance: (I) awk '/Tax/ {print $1, $2}' spreadsheet1.txt The above command searches for the word tax in the file, if tax is found in said file, it prints the first and second columns. (2) awk '{if ($3 ~ /^2012/ print $0)}' spreadsheet1.txt The above awk command gives a conditional statement which prints the whole document(notice the print $0 which means print all) if column 3 contains any row starting with 2012 Less
