Detailed Description

Single builtin-command Execution Functions.

This file contains functions responsible for executing builtin-commands within the project. It includes functions to identify builtins, execute them, and handle single builtin commands.

Function Documentation

◆ execute_builtin()

void execute_builtin ( t_shell * shell )

Execute a builtin-command.

The execute_builtin function executes the appropriate builtin-command based on the provided command name in the execs array. It sets the global g_exit_code variable to the exit status of the command.

Parameters

[in,out] shell A pointer to the shell struct.

◆ handle_single_builtin()

int handle_single_builtin ( t_shell * shell )

Handle the execution of a single builtin-command.

The handle_single_builtin function checks if the provided command is a builtin, saves the file descriptors, handles standard input and output redirections, executes the builtin-command and restores standard file descriptors.

Parameters

[in,out] shell A pointer to the shell struct.

Returns: The status code indicating the execution result.

◆ is_builtin()

bool is_builtin ( char * exec )

Check if a given command is a builtin-command.

This function determines whether the provided command is one of the shell builtin-commands such as "echo", "cd", "pwd", "export", "unset", "env" or "exit."

Parameters

[in] exec The command name to check.

Returns: true if the command is a built-in, false otherwise.
