Shell Programming and Scripting

Hello to all,

I'm trying to format a file to have all lines with the same length (the length of the longest line) adding needed extra spaces at the end.

Currently I have the awk script below that adds one space the end of each that have a lenght lower than 35, but I don't know
how to add dynamically "MaxLenght - each line lenght" spaces.

This is the code I've tried so far:

Code:

awk 'length<35{print $0 " ";next}1' file

For example:
first line has a lenght of 25 --> Then add 10 spaces at the end
first line has a lenght of 10 --> Then add 25 spaces at the end
first line has a lenght of 35 --> Then add 0 spaces at the end
first line has a lenght of 32 --> Then add 3 spaces at the end

Thanks for any help.

Best regards

Code:

echo '12345' | awk -v m=10 '{printf("[%-10s]\n", $0)}'
[12345     ]

Try, untested

Code:

awk -v x=0 '(NR == FNR) { if(length > x) x = length;next } { printf("%-"x"s\n", $0) }' file file

Hello vgersh99, it works and it seems to work without the "-v m=10" part at the beginning.

hello senhia83, Excellent! it works taken dynamically the length of the longest line!

Thank you both.

Best regards
