Grep for the same occurrence or maybe Sed
Hi, I have a file that looks like this
dasdjasdjoasjdoasjdoa SYN dakspodkapsdka asdasdasdasdasdasdasd SYN sdfsdfsdfsdfdf shfishifhsdifhsidhfif fsdfsdfsdfsdfs sdfsdfsdfsdsdfsdfsdff cercercercerce sdasdajsdoajsodasodoo FIN dasdaskdpasdda dkaspdkaskdpaskpaskdp FIN asdasdasdasdas dasdjasdjoasjdoasjdoa SYN dakspodkapsdka asdasdasdasdasdasdasd SYN sdfsdfsdfsdfdf shfishifhsdifhsidhfif fsdfsdfsdfsdfs sdfsdfsdfsdsdfsdfsdff cercercercerce sdasdajsdoajsodasodoo FIN dasdaskdpasdda dkaspdkaskdpaskpaskdp FIN asdasdasdasdas The file is a huge log file with always 2 lines with SYN in exactly the same place one after the other, and also 2 FINS together. We have discovered that we are getting errors where 3 SYN lines are together, and I want to identify where these occurences are ie dasdjasdjoasjdoasjdoa SYN dakspodkapsdka asdasdasdasdasdasdasd SYN sdfsdfsdfsdfdf asdasdasdasdasdasdasd SYN sdfsdfsdfsdfdf shfishifhsdifhsidhfif fsdfsdfsdfsdfs sdfsdfsdfsdsdfsdfsdff cercercercerce sdasdajsdoajsodasodoo FIN dasdaskdpasdda dkaspdkaskdpaskpaskdp FIN asdasdasdasdas Ive looked at using grep to search for '3 SYNS' but i cant seem to get it to work. Does anybody know how i can search for an occurrence of SYN in the same place , three lines running Any help would be greatly appreciated |
