exec

Command Function

This command is a built-in shell command used to execute basic user-mode programs.

Syntax

exec <executable-file>

Parameters

Table 1 Parameter description

Parameter	Description
executable-file	Specifies a valid executable file.

Usage Guidelines

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

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.
