wrong submission in a for loop by usind the sed order


Hey Guys,

I have a problem with my code. I have a lot of .dat files. In these files I want to change one expression to another.

My code is this:

let a=34;

for i in V13_*.dat;

do let a=a+1;
sed -i 's/Slice: Z=0.00635/V13_'$a'/' V13_*.dat;
echo $i;
echo $a;
done

My Problem is that every expression is changed to V13_35 and not to

V13_35
V13_36
V13_37
...

I think I have to submit the a into the sed-function, because echo $a shows

35
36
37
...

Someone get it?

Can you help me?

Tanks a lot.

Your sed is operating on all files at the same time V13_*.dat, it should be operating on "$i"

Good

Please do 2 things though:

1. In future please use [code][/code] tags around code and data to keep its formatting

2. Once you have a solution, please mark question as SOLVED
