chroot时硬链接ldd依赖的脚本

chroot_ln_file.sh

#!/bin/bash

mkdir -p $(dirname $2/$1)
ln $1 $2/$1 &> /dev/null
ori=$(readlink $1)
if [ -n "$ori" ]; then
	real=$(realpath -s $ori)
	if [[ "$real" == "$ori" ]]; then
		$0 $real $2
	else
		$0 $(dirname $1)/$ori $2
	fi
fi

chroot_lnso.sh

#!/bin/bash

ldd $1 | sed 's/^\s*//g' | sed 's/.* => //g' | sed 's/ (0x.*)//g' | grep '^/' | xargs -i $(dirname $0)/chroot_ln_file.sh {} $2

用法：

sudo bash chroot_ln_file.sh /bin/bash /var/chroot
sudo bash chroot_lnso.sh /bin/bash /var/chroot
