Extract lines with string and variable number pattern

hope this fix your issue This matches lines with a value greater than or equal to 0.8. If you insist on strictly greater than, then I'll have to add some complexity to prevent 0.8 from matching.
code :
grep 'DR2=\(1\|0\.[89]\)' myfile

Any of those help As you mentioned in the comments the underscores are fixed and need the data between the second and third underscores, you can use PARSENAME to get your expected data.
Sample execution:
code :
DECLARE @TestString AS VARCHAR (200) = '_999_123456_8888888-123564578'; 
SELECT PARSENAME(REPLACE(@TestString, '_', '.'), 2)

I hope this helps you . I am trying to use awk to extract those lines that in $2 contain exon (some digit that is 1-99) sequence. The text will always be the same but the digit will be variable.
code :
awk -F'\t' '$2 ~ /exon [1-9][0-9]? sequence/' file

seems to work fine I have a file with several columns and I would like to extract only those lines which have in the 8th column a value higher than 0.7 (maximum will be 1). My 8th column looks like this: , Something like can do the work:
code :
awk  '$8 ~ /^DR2=/ { if (substr($8,5) > 0.7) print }' myfile > myfile.filtered

hop of those help? It's not entirely clear what you're trying to do but i think you're saying you want to print the version value when a specific string appears in the record. If so that's just:
code :
$ awk -v str='linux-source_4.19+103_all.deb' -F': *' '{f[$1]=$2} index($0,str){print f["Version"]}' file
103
$ awk -v str='linux-source_4.19+103_all.deb' -v dist='buster' -v src='linux-latest' -F': *' '
    { f[$1] = $2 }
    (f["Distribution"]==dist) && (f["Source"]==src) && index($0,str) { print f["Version"] }
' file
103
