如何显示Linux中可执行文件使用的所有共享库?

问题描述

我想知道系统上的可执行文件使用了哪些库.更具体地说，我想对使用最多的库以及使用它们的二进制文件进行排名.我该怎么办?

I'd like to know which libraries are used by executables on my system. More specifically, I'd like to rank which libraries are used the most, along with the binaries that use them. How can I do this?

推荐答案

1. 使用ldd列出每个可执行文件的共享库.
2. 清理输出
3. 排序，计算计数，按计数排序

1. Use ldd to list shared libraries for each executable.
2. Cleanup the output
3. Sort, compute counts, sort by count

要找到"/bin"目录中所有可执行文件的答案，请执行以下操作:

To find the answer for all executables in the "/bin" directory:

find /bin -type f -perm /a+x -exec ldd {} \; \
| grep so \
| sed -e '/^[^\t]/ d' \
| sed -e 's/\t//' \
| sed -e 's/.*=..//' \
| sed -e 's/ (0.*)//' \
| sort \
| uniq -c \
| sort -n

将上面的"/bin"更改为"/"以搜索所有目录.

Change "/bin" above to "/" to search all directories.

输出(仅用于/bin目录)将如下所示:

Output (for just the /bin directory) will look something like this:

  1 /lib64/libexpat.so.0
  1 /lib64/libgcc_s.so.1
  1 /lib64/libnsl.so.1
  1 /lib64/libpcre.so.0
