Examples of common uses of OBJDUMP commands in Linux:

Objdump-x obj: The data of the target file is composed in the form of a sort of information output;< all dynamic libraries that can be found in the file >

Objdump-t obj: Symbol table for Output destination file ()

Objdump-h obj: Summary of all segments of the output destination file ()

Objdump-j./text/.data-s obj: Output information for the specified segment (Disassembly source code)

Objdump-s obj: The symbol table for the output destination file () prints more clearly when gcc-g

Objdump-j. TEXT-SL Stack1 | More

-S to disassemble the source code as much as possible, especially when you specify the debug parameter of-G when compiling,

The effect is more obvious. The-d parameter is implied.

-l labels the corresponding target code with the file name and line number, only with-D,-D, or-R

The difference between using-LD and using-D is not very large, useful when debugging at the source level, requiring

Debug compilation options such as-G are used at compile time.

-j Name displays only the information for the specified section

How do I disassemble any binary file using the Linux objdump command ?

You can use the following command:

Objdump-d-B binary-m i386 A.bin

-d means disassembly of all files,-B for Binary,-m for instruction set schema, A.bin is the binary we want to disassemble

Objdump-m can view more supported instruction set schemas, such as i386:x86-64,i8086, etc.

The parameters of all Objdump commands above also apply to Arm-linux-objdump.

At the same time we can specify Big-endian or Little-endian (-eb or-el), we can specify from a location to start disassembly and so on.

The objdump command is a command to disassemble a target file or executable file under Linux, and it has other functions, as an example of the ELF format executable test in detail:

Objdump-f Test Displays the file header information for test

Those sections in objdump-d test disassembly test that require execution of instructions

Objdump-d test is similar to-D, but all sections in the Disassembly test

Objdump-h Test Displays section header information for test

Objdump-x Test Displays all header information for test

Objdump-s Test Displays all header information for test, as well as their hexadecimal file code
