Effective grep of log file

Question

I have a log file with a lot of lines on this format:

10.87.113.12 - - [2019-12-09T11:41:07.197Z] \"DELETE /page/sub1.php?id=alice HTTP/1.1\" 401 275 \"-\" \"ali         


        

Answer 1

Could you please try following, this should be an easy task for awk in case you are ok with awk.

awk '
/alice/ && match($0,/jw_token=[^ ]* HTTP\/1\.1\" 200/){
  val=substr($0,RSTART+9,RLENGTH-9)
  split(val,array," ")
  print array[1]
  delete array
}'  Input_file
