[Chicago-talk] Replacing consecutive newlines with a single newline

[Vijay Kumar]

Sorry for not being clear about the problem. The intention was to
replace consecutive 2+ multiple blank lines with 2 blank lines.

Today I checked-in some code like below that formats Oracle's spool output.

    perl -0777 -pi -e 's/^SQL>//mg; s/\n{2,}/\n\n/g' inputfile
    cat inputfile | mailx ....

and obviously giving credit to Andy in the comments and explaining about 0777.

Thanks
VIJAY
