Question

What needs to be added to the gawk statement in the print command (between $3 and $1 )to place a space between the output fields. Test this command, the output isn't very readable. Adding one thing to the command will improve readability. gawk '/chevy/ {print $3 $1}' cars.txt

Answer 1

gawk '/chevy/ {print $3 $1}' cars.txt

instead of print in above command we can use printf to improve the readability of the output, So if we use printf there we can format the output.

Ex:gawk '/chevy/ {printf("%3s\t%s\n", $3,$1) }' cars.txt

Here in this command we are adding tabs in between $3 and $1 contents. Like this we can format the string however we want using printf statement.
