Answer 1

awk '{ print $2 }' text.txt > outputfile.txt 

> => This will redirect STDOUT to a file. If file not exists, it will create it. If file exists it will clear out (in effect) the content and will write new data to it

>> => This means same as above but if file exists, this will append new data to it.

Eg:

$ cat /etc/passwd | awk -F: '{ print $1 }' | tail -10 > output.txt $ cat output.txt  _warmd _dovenull _netstatistics _avbdeviced _krb_krbtgt _krb_kadmin _krb_changepw _krb_kerberos _krb_anonymous _assetcache 

Alternatively you can use the command tee for redirection. The command tee will redirect STDOUT to a specified file as well as the terminal screen

There is a way to do this from within awk itself (docs)

➜ cat text.txt line 1 line 2 line three line 4 4 4  ➜ awk '{print $2}' text.txt 1 2 three 4  ➜ awk '{print $2 >"text.out"}' text.txt  ➜ cat text.out 1 2 three 4
