In Golang, executing external commands is simplified with the os/exec package. However, directly executing a bash script using this method may present challenges. This article delves into an alternative approach for executing an entire bash script.
For the script to be executable from Go, it must adhere to certain requirements:
If the script does not meet these requirements, an alternative approach is to execute it indirectly using a custom command.
Option 1: Indirect Execution
Use exec.Command to invoke the /bin/sh shell and pass the script's path as an argument.
cmd := exec.Command("/bin/sh", mongoToCsvSH)
Option 2: One-Liner Command
Concatenate the script's path with the /bin/sh command in a single string.
cmd := exec.Command("/bin/sh " + mongoToCsvSH)
By employing these methods, you can successfully execute bash scripts from within Golang. Remember to adapt the code snippets based on your specific script's requirements.
