Awk print format number

x2 In AWK, the first field is referred to as $1, the second as $2 and so on. So an AWK program to retrieve Audrey's phone number is: awk '$1 == "Audrey" {print $2}' numbers.txt which means if the first field matches Audrey, then print the second field. In awk, $0 is the whole line of arguments.For instance, to print the home directories of all users on the system, you might do awk < /etc/passwd -F: '{ print $6 }' since the password file has fields delimited by colons and the home directory is the 6th field. Arithmetic Awk is a weakly typed language; variables can be either strings or numbers, depending on how they're referenced.The printf format for converting numbers to strings in output statements (see Output Statements ); %.6g by default. The result of the conversion is unspecified if the value of OFMT is not a floating-point format specification. OFS The print statement output field separation; a space character by default. ORSThe awk command above is pretty straightforward. It prints a line with its line number if both conditions are satisfied: NR >= 6 - Its line number must be greater than or equal to six. /Exception/ - The line must contain the word "Exception". As we've seen in the output, we've got the required lines containing the word "Exception".PS re OP: That does work in bash: printf "%'d\n" 12345678. 12,345,678.
