  • Do you mean the last commnd to be executed or specifically the last shell script? If you run /tmp/start.sh; ls will you want ls as output or start.sh?

    @yael Huh? Could you elaborate on what it is that you actually want to do, exactly? Please do so in the question itself.

    Can you explain what you are trying to do. This seems like an AB question. That is you are trying to do A, can see that you can do it via B, and ask how to do B. It may be easier to just do A.

    It really isn't simple. For one thing, how do you define previous? What if another user ran something in a different session? What if the same user ran something but in a different session (e.g. another terminal)? Which command should be found then?

Using history expansion in an interactive bash shell:



$ /some/path/script.sh






$ printf 'Basename of last command line: %sn' "$(basename "!!")"

printf 'Basename of last command line: %sn' "$(basename "/some/path/script.sh")"

Basename of last command line: script.sh


The !! is a history expansion event designator, which will be replaced by the last command. See the "HISTORY EXPANSION" section in your bash manual.



Note that !! will expand to the full command line.




In a shell script, you always know what the previous script was called, because you just typed it in.



/some/path/script.sh



echo 'script.sh just finished'

Accessing regular linux commands in Huawei's Dopra Linux

4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. 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".
