Describe Bug

I want to use post compile command to generate a disassemble files of elf. But the os.exec failed to recognize the io redirect operator ">".

os.exec("arm-none-eabi-objdump -S build/cross/cortex-m4/release/minimal-proj > build/minimal-proj.asm")

The output content is not written to a file but directly dump in the shell. The command failed at char ">". The actually executed commands seems to be the following.

$ arm-none-eabi-objdump -S build/cross/cortex-m4/release/minimal-proj '>' build/minimal-proj.asm

Expected Behavior

It should just work like executed in shell and redirect the output of arm-none-eabi-objdump to a file called "build/minimal-proj.asm".

$ arm-none-eabi-objdump -S build/cross/cortex-m4/release/minimal-proj > build/minimal-proj.asm

Project Configuration

after_build(function (target)
      os.exec("arm-none-eabi-objdump -S build/cross/cortex-m4/release/minimal-proj > build/minimal-proj.asm")
end)

Additional Information and Error Logs

When I directly run the command in shell, it could success to generate the asm file.

 arm-none-eabi-objdump -S build/cross/cortex-m4/release/minimal-proj > build/minimal-proj.asm
# success to gen  build/minimal-proj.asm

When I use the os.exec, it failed to output to the "build/minimal-proj.asm" file but directly dump the content to shell.

$ xmake b -vD
....
print asm file content

[fripSide]

Currently, I need to use os.iorun to capture the results.

local asm = os.iorun("arm-none-eabi-objdump -S build/cross/cortex-m4/release/minimal-proj")
io.writefile(gen_fi..".asm", asm)

os.execv("echo", {"hello", "xmake!"}, {stdout = outfile, stderr = errfile}
