how to extract ascii separated values in a text file?
 

Hi,

I have one file consisting of lines which has some info separated by "|". I want to grep the file and provides me a list of records on the 3rd, 4th entry on a single line. How will this be possible? I am guessing should be using "sed" but not an expert. Also wondering if you can provide me a good reference for logs and values manipulation. Thanks.

Do you mean the 3rd and 4th fields on the records that get through grep?

That could be achieved with:
it could also be down in awk with something like:

sed could do it too, but I think that would be a little more complicated.

Given file t.t
then
HTH

Thanks guys...Now another complicated thing is that inside the file, there are few texts and this information is in the middle of the line.

Example:

some text some text [A|B|C|D] some text some text

I want to check the pattern "II" in that line and output only those lines with that content and if possible only those starting with "[" and ending with "]".

Thanks.

I think something like

would work
