Find specific line and delete line after.
I'm looking for a way to search a file, in this case init.rc for a specific match, service adbd /sbin/adbd, and delete the a specific line after it
Original:
Code:
# adbd is controlled by the persist.service.adb.enable system property
service adbd /sbin/adbd
    disabled

After deletion:
Code:
# adbd is controlled by the persist.service.adb.enable system property
service adbd /sbin/adbd

I can't just search for "disabled" because there are multiple instances within the file and I need to delete just this one directly after this line in this file.

HTML Code:
awk '/service adbd \/sbin\/adbd/{print;getline;next}1' infile

Same thing in sed:
Code:
sed '/service adbd \/sbin\/adbd/{n;d}' infile

<strikethrough> sed -n 'p;/service adbd \/sbin\/adbd/{N;d;}' infile </strikethrough>

...

@Scurti , ok your solution is better (i fixed a little typo : semicolon was missing)

Code:
sed '/service adbd \/sbin\/adbd/{n;d;}' infile
