Top Forums Shell Programming and Scripting Delete block of text in one file based on list in another file Post 302350158 by ripat on Thursday 3rd of September 2009 02:19:50 AM

Or in awk, this seems to produce the desired output with the given sample files:

Code:
awk 'FNR>=NR{a[" Using archive: "$0]=1;next}{RS=ORS="\n\n";FS="\n"}!a[$2]{print}' listfile datafile

I don't like too much the {RS=ORS="\n\n";FS="\n"} bloc that executes on every lines of the second file but I don't know how do avoid this. Can't do that variable assignment in the BEGIN bloc as the first file will then not be parsed correctly. Any idea?


Edit
The only thing I could think of is to flag the variable assignment so that when it is done once, skip it on the next line:
Code:
awk 'FNR>=NR{a[" Using archive: "$0]=1;next}!f{RS=ORS="\n\n";FS="\n";f=1}!a[$2]{print}' flle1 flie2
