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"

This works fine Smilie

Thx a lot

mhhhh
if i use:
Code:
file="/home/bags/Scrivania/0280.u3_capitolo15.pdf"
pdfinfo -box "$file" | awk '/^MediaBox:/ {m2=$2;m3=$3;m4=$4;m5=$5} /^TrimBox:/{print m2-$2 ,m3-$3 ,$4-m4 ,$5-m5}

I obtain right values.
but If I use the whole part:
Code:
file="/home/bags/Scrivania/0280.u3_capitolo15.pdf"
pdfcrop --margins $(pdfinfo -box "$file" | awk '/^MediaBox:/ {m2=$2;m3=$3;m4=$4;m5=$5} /^TrimBox:/{print m2-$2 ,m3-$3 ,$4-m4 ,$5-m5}')" "$file"

I obtain an error Smilie
Code:
PDFCROP 1.23, 2010/01/09 - Copyright (c) 2002-2010 by Heiko Oberdiek.
!!! Error: Input file `' not found!

seems wrong in command expression Smilie

I should have:
Code:
pdfcrop --margins '-42.50 -42.50 -42.50 -42.49' '/home/bags/Scrivania/0280.u3_capitolo15.pdf' '/home/bags/Scrivania/0280.u3_capitolo15.pdf'
