Got a RHEL 7.9 server. Seems the networkmanger package is installed but no service added. Is there a way that I can manually add the service? # yum install NetworkManager Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager This system is not registered with an entitlement server. You can use subscription-manager to register. local | 2.8 kB 00:00:00 Package 1:NetworkManager-1.18.8-1.el7.x86_64 already installed and latest version Nothing to do # systemctl start networkmanager Failed to start networkmanager.service: Unit not found. # cat /etc/*release NAME="Red Hat Enterprise Linux Server" VERSION="7.9 (Maipo)" ...

I'm currently doing a nm like program, to print the symbols of an ELF file with their addresses and their type. The typical output is something like :

$ nm ./my_exec      
0000000000003d28 d _DYNAMIC
0000000000003f28 d _GLOBAL_OFFSET_TABLE_
0000000000002000 R _IO_stdin_used
                 w _ITM_deregisterTMCloneTable
                 w _ITM_registerTMCloneTable

The first column is the symbol address, the second is the symbol type and the third, the symbol name. The man indicates the meaning for each character, upper-case is a global symbol, lower-case is local symbol etc... But I don't understand *how* it choose which character to use. I'm using the Gelf library and I didn't see a field from where I could determine the character.

I would like to find the symbol "start" for example in all object files recursively down from the directory I'm in. I think I can use nm or readelf, but I'm new to shell and not understanding how to do this from the manual.

I expected to see number of symbols in the **libc.so.6** file including **printf**. I used the **nm** tool to find them, however it says there is no symbol in libc.so.6.

I used nm command to inspect the function names in a .so library. And the result I got is like this: 00009634 T _Z24ICTCLAS_ParagraphProcessPKciPc9eCodeTypeb 00009764 T _Z25ICTCLAS_ParagraphProcessAPKciRi9eCodeTypeb 00009b24 T _Z26ICTCLAS_ParagraphProcessAWPKcP17tagICTCLAS_Result9eCodeTypeb Actually there are functions called ParagraphProcess and ParagraphProcessA. But how to interpret the prefix(_Z24ICTCLAS_) and suffix(PKciPc9eCodeTypeb) and the address-like string(00009634) at the start of the line?

I am looking for a specific symbol in a bunch of shared libraries, I am using the following command: find . -iname "*.so" | nm -D //loop over output of find | grep -e symbol How can I tell nm -D to loop over find results ? Thanks

Where does the name of nm come from? The IEEE standard defines nm as: nm - write the name list of an object file Is nm an abbreviated form of word name/names? Or does it have a completely different origin?
