hi
thank you for replay
i have the following text file

seg{
            ax 3100,
           as 2,
           az 112,
            aq 1,
            },
        seg { 
            ax 3100,
            as 2,
            az 137,
          aq 4,

        },
     seg { 
          ax 3100,
            as 2,
            az 22,
            aq 8,
            },



        now i want to divide the text file to parts such that each part contain a seg block
         seg { 
        ax 3100,
        as 2,
        az 137,
      aq 4,
       },
    and from each seg construct the following
    ax.as.az.aq
    to become the following 
    3100.2.137.4
    co how can i do this in shell script?????

I suppose you mean break the main file into smaller files containing only one seg part each.

how can i do this in shell script?????

as you're working on interval (between seg{ and },) it'd be easy to use sed,
but I don't know how to generate file names from within.
so, I suggest you use awk.
not every awk does work on interval as easily as sed, even it's a bit tedious, it's not difficult to say: if line is "seg{", then process begins, else if line is "},", then process ends, endfi (more or less).

Edit:
you could also split the main file into 6 lines files, and transform each using sed.

thank you for replay i donot want to put each segment in a file because my text file contain 60 seg so it will be a lot of files cannot i process what i want without using files and you explain more about the commands because i am new to shell script

it's your homework, you have to build an algorithm, and use the language you've been taught, so you learn!
