Recording particular cell of a table on the basis of a certain condition using grep-CodePudding

I have a number of tables that looks as follows:

 time | node  | left  |LP iter|LP it/n|mem/heur|mdpt |vars |cons |rows |cuts |sepa|confs|strbr|  dualbound   | primalbound  |  gap   | compl.

I'm interested in recording the first numeric value in the gap column (second last column of the table). The gap column could either have Inf or x.xx% values in it. If all the values in the gap column are Inf, then I would simply record Inf, otherwise, I would like to record the first numeric value. For e.g. in the above table, the value that I would like to record is 0.17. I tried many different ways but couldn't achieve any success. It would be really great if someone could provide some guidance as to how to achieve the above-mentioned objective. Thanks !

CodePudding user response：

You may use this awk solution:

awk -F '[[:blank:]]*\\|[[:blank:]]*' '
NR > 1 && (!v || v == "Inf") {
   v = ($(NF-1) == "Inf" ? $(NF-1) : $(NF-1) 0)
}
END {
   print v
}' file
