Help with cp command to copy library files
Hi,

I have to copy *.so shared objects filtering out the files having *.debug extension and if symbolic link is present copy only the links excluding the source (i.e) if it is a symbolic link then it should not de-reference the source file. For this I used the "-P" option, but I am not sure, whether it is correct.

Consider the files as:
Code:
$ ls libRuntime*.so*

libRuntimeCore.so
libRuntimeCore.so.1
libRuntimeCore.so.1.4.0
libRuntimeCore.so.1.4.debug  # have to exclude this file while copying
libRuntimeCore.so -> libRuntimeCore.so.1.0.0  # copy only the link

I came up with a command
Code:
find . -type f -name "lib*.so.*" | grep -v debug | xargs -I '{}' cp -P '{}' .

Is there any other command simpler than this to accomplish my task? Also please help me to understand to how to use regular expression in cp command.

If I were you I would to do like this :

Firstly copy normal files exclude debug so list all file name matched "lib*.so.*" pattern and let be max line count is one and copy these to mysourcedir..
Code:
find . -type f -name "lib*.so.*" ! -name "*debug" -print0 | xargs -0 -L 1 cp -t /mysourcedir

Secondly the controlly remove the incorrect symbolic links file (with prompt)
Code:
find -L -name "lib*.so*" -type l -print0 | xargs -0 -L 1 rm -i

And latest copy correct symbolic links file
Code:
find -H -name "lib*.so*" -type l -print0 | xargs -0 -L 1 cp -t /mysourcedir  -P

Thank you for the help.

But can you tell me, suppose if the library *.so files are residing in the sub-directories as well and if I want to descend into these directories and copy all the *.so files into another directory (without copying the directory itself), how do I do it using cp? Because cp -R or cp -r does not help. I guess I could use "find" command in this scenario. Am I right?

this find itself should find and give files from sub directories also.

find command default works in depth as already say thegeek..so recursive copy is unnecessary in this Smilie
