Code:
second -42.50 --> 0.00-42.50; third -42.50 --> 680.27-637.77; last -42.49 --> 898.53-856.04

last two values should be positive.

Code:
file=/home/bags/Scrivania/0280.u3_capitolo15.pdf
pdfcrop --margins "$(pdfinfo -box "$file" |awk '/^MediaBox:/ {m1=$2;m2=$3;m3=$4;m4=$5} /^TrimBox:/{print m1-$2,m2-$3,m3-$4,m4-$5}')" "$file"

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
