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.

          In sed, this should work:



          sed '/url/ { /scm/! s=.com/=.com/scm/=g }'


          You can negate an andress by adding a ! after it, and you can apply an address regex to another by using blocks.



          Or maybe, if scm only afer .com/ should be checked for:



          sed '/url/ { =.com/scm/= ! s=.com/=.com/scm/=g }'

                    0 I am on a system dual-booting Windows and Debian (usually using the latter), and a recent Windows update appears to have wreaked havoc on the Debian boot system. I managed to boot Windows again, but not Linux. Following online suggestions, I created a Live USB of Ubuntu, and booted from that. Then I have installed and run the boot-repair utility. The utility instructs me to type several lines including sudo chroot "/mnt/boot-sav/sda6" apt-get purge -y grub*-common grub-common:i386 To which I receive the error E: Unable to locate package grub-common:i386 I am given to understand the issue may have to do with having UEFI vs BIOS (I believe I have UEFI), but do not understand this well.
