How can I ensure some shell or bash option is enabled or disabled and later on restore it if I have changed...












0















Sometimes I want to do something which requires some shell or bash option enabled or disabled. For example, https://unix.stackexchange.com/a/108520/674



So I could first change the shell or bash option to the desired state, and do something that I want, and then restore the shell or bash option.



But I might not necessarily need to change some shell or bash option, if it has already been what I want it to be. so there is no need to restore it after I finish doing what I want to do.



So what can I do?



Thanks.

My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell".
