sed and awk challenge [closed]

Question

Here is a great challenge for someone to attack!

Is there a way to achieve the following using sed and/or awk. Please see myfile.txt below:

$cat myfile.txt:

entry

"entry-header"

entry-top

name

!udwd870kdjll   --  random string

Derek

code=nsmssdllskpdp

code=nassmdllskpdp

name

!ueo0000kdjll   --  random string

name

Moss

!ueo3870kdjll   --  random string

choice=Pear comments="Great"

choice=Pineapple comments="Not quite the best"

choice=Apple comments="OK"

choice=Grapes comments="OK"

choice=Grapefruit comments="OK"

/entry-top

/entry



entry

"entry-header"

entry-top

!udwd870kdjll   --  random string

name

!udwd870kdjll   --  random string

Sarah

code=nsmsstyyukpdp

code=nalmdllskpdpx

!ueo0000kdjll   --  random string

name

Zimmerman

!ueo3870kdjll   --  random string

choice=Orange comments="These are awesome"

choice=Pineapple comments="Nice"

choice=Mango comments="Pretty good"

/entry-top

/entry

etc...

This is a huge list of peoples favorite fruits, and their entries are in order, with the one at the top being the favorite. I need to be able to assign a number to each entry so I can collate the results. I also need to differentiate between the two name lines given, the surname always appeasr second. As long as I can update the labels (to be name1 and name2 rather than name and name), I will be able to manipulate the text how I want to.

The required output is below, and should show you exactly what I am after:

entry

"entry-header"

entry-top

name1

!udwd870kdjll   --  random string

Derek

code=nsmssdllskpdp

name2

code=nassmdllskpdp

!ueo0000kdjll   --  random string

Moss

!ueo3870kdjll   --  random string

choice1=Pear comments="Great"

choice2=Pineapple comments="Not quite the best"

choice3=Apple comments="OK"

choice4=Grapes comments="OK"

choice5=Grapefruit comments="OK"

/entry-top

/entry



entry

"entry-header"

entry-top

name1

!udwd870kdjll   --  random string

Sarah

code=nsmsstyyukpdp

name2

code=nalmdllskpdpx

!ueo0000kdjll   --  random string

Telford

!ueo3870kdjll   --  random string

choice1=Orange comments="These are awesome"

choice2=Pineapple comments="Nice"

choice3=Mango comments="Pretty good"

/entry-top

/entry

Answer 1

Since this seems to be homework, I'm tempted not to give you anything, but in the interest of learning I'll give you this sed script to chew on:

/^entry$/{:a;n;s/^name$/name1/;tb;ba;:b;n;s/^name$/name2/;tc;bb;:c}

Note that on non-gnu systems you may need to put each command on a separate line.
