如何将程序依赖的动态库拷贝到指定的目录？

例子

1、通过LDD查看依赖的动态库。

# ldd postgres  linux-vdso.so.1 =>  (0x00007ffcfc324000)  libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fb6151ba000)  libxml2.so.2 => /lib64/libxml2.so.2 (0x00007fb614e4f000)  libpam.so.0 => /lib64/libpam.so.0 (0x00007fb614c40000)  libssl.so.10 => /lib64/libssl.so.10 (0x00007fb6149ce000)  libcrypto.so.10 => /lib64/libcrypto.so.10 (0x00007fb61456c000)  libgssapi_krb5.so.2 => /lib64/libgssapi_krb5.so.2 (0x00007fb61431f000)  librt.so.1 => /lib64/librt.so.1 (0x00007fb614117000)  libdl.so.2 => /lib64/libdl.so.2 (0x00007fb613f12000)  libm.so.6 => /lib64/libm.so.6 (0x00007fb613c10000)  libldap-2.4.so.2 => /lib64/libldap-2.4.so.2 (0x00007fb6139bc000)  libicui18n.so.50 => /lib64/libicui18n.so.50 (0x00007fb6135bc000)  libicuuc.so.50 => /lib64/libicuuc.so.50 (0x00007fb613243000)  libsystemd.so.0 => /lib64/libsystemd.so.0 (0x00007fb61321b000)  libc.so.6 => /lib64/libc.so.6 (0x00007fb612e59000)  /lib64/ld-linux-x86-64.so.2 (0x00007fb6153e1000)  libz.so.1 => /lib64/libz.so.1 (0x00007fb612c43000)  liblzma.so.5 => /lib64/liblzma.so.5 (0x00007fb612a1d000)  libaudit.so.1 => /lib64/libaudit.so.1 (0x00007fb6127f4000)  libkrb5.so.3 => /lib64/libkrb5.so.3 (0x00007fb61250c000)  libcom_err.so.2 => /lib64/libcom_err.so.2 (0x00007fb612308000)  libk5crypto.so.3 => /lib64/libk5crypto.so.3 (0x00007fb6120d4000)  libkrb5support.so.0 => /lib64/libkrb5support.so.0 (0x00007fb611ec6000)  libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x00007fb611cc2000)  libresolv.so.2 => /lib64/libresolv.so.2 (0x00007fb611aa7000)  liblber-2.4.so.2 => /lib64/liblber-2.4.so.2 (0x00007fb611898000)  libsasl2.so.3 => /lib64/libsasl2.so.3 (0x00007fb61167b000)  libssl3.so => /lib64/libssl3.so (0x00007fb61142e000)  libsmime3.so => /lib64/libsmime3.so (0x00007fb611207000)  libnss3.so => /lib64/libnss3.so (0x00007fb610edd000)  libnssutil3.so => /lib64/libnssutil3.so (0x00007fb610caf000)  libplds4.so => /lib64/libplds4.so (0x00007fb610aab000)  libplc4.so => /lib64/libplc4.so (0x00007fb6108a6000)  libnspr4.so => /lib64/libnspr4.so (0x00007fb610667000)  libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007fb61035f000)  libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007fb610149000)  libicudata.so.50 => /lib64/libicudata.so.50 (0x00007fb60eb74000)  libcap.so.2 => /lib64/libcap.so.2 (0x00007fb60e96f000)  libselinux.so.1 => /lib64/libselinux.so.1 (0x00007fb60e748000)  libgcrypt.so.11 => /lib64/libgcrypt.so.11 (0x00007fb60e4c6000)  libgpg-error.so.0 => /lib64/libgpg-error.so.0 (0x00007fb60e2c1000)  libdw.so.1 => /lib64/libdw.so.1 (0x00007fb60e079000)  libcap-ng.so.0 => /lib64/libcap-ng.so.0 (0x00007fb60de72000)  libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007fb60dc3b000)  libattr.so.1 => /lib64/libattr.so.1 (0x00007fb60da35000)  libpcre.so.1 => /lib64/libpcre.so.1 (0x00007fb60d7d3000)  libelf.so.1 => /lib64/libelf.so.1 (0x00007fb60d5bb000)  libbz2.so.1 => /lib64/libbz2.so.1 (0x00007fb60d3aa000)  libfreebl3.so => /lib64/libfreebl3.so (0x00007fb60d1a7000)

2、写一个SHELL脚本，自动拷贝依赖的动态库。

vi test.sh  deplist=$( ldd $1 | awk '{if (match($3,"/")){ print $3}}' )
cp -L -n $deplist $2

-L 表示拷贝文件（如果是软链，会拷贝到最终的文件）。
-n 表示不覆盖已有文件。

3、创建目标目录。

mkdir /tmp/lib

4、将postgres依赖的动态库拷贝到目标目录

. ./test.sh /usr/pgsql-10/bin/postgres /tmp/lib/
