How Can I Execute Complex Shell Scripts Using Go\'s `exec.Command()`?

Executing Commands Using exec.Command in Golang

When working with Go and goroutines, the exec.Command() function is commonly used to execute system commands. However, difficulties arise when attempting to execute complex shell scripts that involve multiple programs linked via shell syntax.

To address this issue, it's crucial to understand that exec.Command() directly calls the kernel to execute the specified process, bypassing the shell's script interpretation. When passing a shell script as a string, the kernel is unable to interpret the shell syntax used to link the programs together.

Therefore, to execute shell scripts successfully, Go provides a more appropriate approach:

cmd := exec.Command("/bin/sh", "-c", "sudo find ...")

In this updated code, "/bin/sh" is the interpreter responsible for executing the shell script and "-c" represents the execution command, where the shell script is provided as the argument to be interpreted by the shell.

By using this approach, Go can effectively execute complex shell scripts that the user has provided, enabling them to perform tasks that involve multiple programs and shell commands.
