How to apply sed if it contains one string but not another?












0















I'm trying to convert this



url = ssh://git@git.company.com/project/repo.git


to



url = ssh://git@git.company.com/scm/project/repo.git


However, it's not a simple sed find and replace. I'd like it to only apply the find and replace if the string starts with turl and doesn't already contain scm.



I have the beginning portion where it will only replace lines containing turl



cat .git/config | sed "/turl/ s=.com/=.com/scm/=g"


but to make this idempotent, I'm having trouble checking if it contains the scm string already. Otherwise if I keep running the command with seds -i then it will keep adding scm.






sed






share

          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". I can't seem to get su access, even after logging in as root (challenge password prompt, and then nothing happens), but shell gives me a proper linux shell.
