Shell Programming and Scripting

I am about to do a script that change the COST so i dont need to change each cost.
The output looks like this.

Code:

"OL_ID       OL_LINK_COST

----------- ------------

         51           10

         52           10

         53           10

         54           10

         55           10

         56           10

         57           10

         58           10

         59           10

So for each OL_ID i want to change OL_LINK_COST to whatever.
So for each line i want to change that line to something.
Dont need any perfect answers just a bit a tip.

Thank you!

just example:

Code:

awk '$2 == 10{$2=20;}{print}' file

for every second field with value 10, change to 20. then print line and every other line.

Maskot,
See if this will do for you:

Code:

sed 's/ .*/ whatever/' input_file

Thank you for the answers!

Didnt had much time when i wrote the thread ill try to explain a bit further.

First of all COST doesnt have to be 10, it can change.
Second it isnt actually the 3rd letter it is like the 23/24 letter which is the COST value.

When i did the copy/paste phase it just happend to get to there.
It actually looks more like this:
space, space, space, space, space 51 space, space, space, space, space, space, space, space and on. 10

i will do a variable which is like cost=30
then
let $cost + COST_LINK
So each COST_LINK will be change in the loop. But the hard part for me is to actually change it.

Not at work atm, will try your kind replys tomorrow

Thank you
