Thanks for the replies, but I don't think I covered the search fully. The data I am searching for can be anywhere on the line, and the line can be very large so I can't cut it. I am searching for data, but I don't know what the data is. I know what it starts with and what it ends with. example @(#) data > so I need to be able to cut upto the @(#) and then after the first > . This could also appear a few times in the same file but with different data. I have tried grepping and putting '.......' in place but the data is variable in size, so I can get a lot of rubbish after the >. I will start to look into sed.
