找出某个库文件属于哪个包的方法

1. 

find out which shared library package contains this shared library file: One quick and easy way to do this is to simply enter the name of the shared library into the Google Linux search at . If you enter the text libcrypto.so into this search page, you'll quickly learn that this shared library is provided by the openssl package.

2. 查看某个rpm依赖哪些库/文件， 比如要找到expect这个rpm包依赖哪些文件， 这样：

# rpm -Rq expect

/bin/sh  

libc.so.6  

libc.so.6(GLIBC_2.0)  

libc.so.6(GLIBC_2.1)  

libc.so.6(GLIBC_2.1.3)  

libc.so.6(GLIBC_2.3)  

libc.so.6(GLIBC_2.3.4)  

libc.so.6(GLIBC_2.4)  

libdl.so.2  

libexpect5.43.so  

libm.so.6  

libm.so.6(GLIBC_2.0)  

libpthread.so.0  

libtcl8.5.so  

libutil.so.1  

libutil.so.1(GLIBC_2.0)  

rpmlib(CompressedFileNames) <= 3.0.4-1

rpmlib(PayloadFilesHavePrefix) <= 4.0-1

rtld(GNU_HASH)  

# -R, --requires

    List packages on which this package depends.

# yum provides *libtcl*

# 这样就可以知道需要哪个rpm包来提供这个库文件
