!The Field Separator It doesn't just have to white space between fields. In can be anything as long as you set the appropriate field separator. Eg: *echo "123:456:789" | awk -F ':' '{print $1,$2,$3,}' The '':'' after the ''-F'' tells us that '':'' is the input field separator. Change this as appropriate. !Multiple Field Separators. What if there are multiple characters you wish to use as field separators? After the ''-F'' just list all of the characters in square brackets. For example: *echo "123:456=789" | awk -F '~[:=]' '{print $1,$2,$3}' !Using Bash Variables inside awk. To use the value of a bash variable. You have to use the ''-v'' switch to import it. The syntax is: *awk -v awkvar=$bashvar {print awkvar} Now you can use awkvar in your awk statements which will have the value of bashvar. Remember you *CANNOT* change the value of a bash variable using [AWK].
