Print Line above and line below
Hello evryone,

I am looking for a way to print x line above and x line below ...

The idea is : I've got a little script that I am trying to make it universal to read debug log file.

I search for specific error value ( ERROR, Failed, NOK) and so on..., but most of the time more info can be useful above and below the line printed.

I am lookink for a way, in interative script to select value above and below the line printed but I didn't find any post to help me on this.


Like print 2 lines above and 3 lines below the line printed with the word ERROR for exemple ....


I hope, someone will be able to help me. Please I can only user ksh. I can't use Perl.

Thanks in advanced for your help.
