Command Function
This command is a built-in shell command used to execute user-space programs.
Syntax
exec <executable-file>
Parameters
Table 1 Parameter description
Usage
Currently, this command supports only valid binary programs. The programs are successfully executed and then run in the background by default. However, the programs share the same device with the shell. As a result, the output of the programs and the shell may be interlaced.
Example
Example:
Run exec helloworld.
Output
OHOS # exec helloworld
OHOS # hello world!
NOTE: After the executable file is executed, the prompt OHOS # is printed first. The shell exec command is executed in the background, causing the prompt to be printed in advance.
