exec

Additional Notes

exec is a shell command used to replace the shell with another command. It replaces the current shell process with a new command without creating a child process. This is useful in scripts to avoid leaving a shell process running after the command completes.

Syntax

exec [arguments]

Parameters

• options: Flags that change how exec behaves.
• arguments: Values consumed by the shell builtin or script command.
• command: Command line to run, test, wrap, or control.

Common Options

• --help: Show command help when supported.
• --version: Show version information when supported.

Examples

exec --help
man exec

Practical Notes

Options can vary by distribution and package version. Use man exec, exec --help, or the package documentation for exact syntax.
