Scan a file for linked libraries recursively and generate list of distinct libs needed in a chroot

chroot-liblist.sh

#!/bin/ksh
libslist=$(ldd $1|grep rlib|awk '{print $NF}')
echo $1>paths.lst
for i in $libslist;do 
        echo $i
        ldd $i|grep rlib|awk '{print $NF}'
done|sort -u >>paths.lst
cat paths.lst
