OK, but that is both hypothetical since the OP did not specify this, and not very typical anyway to have two fields with the same description.
And even if it were the case the sed solution would make this quite controllable.
yes, its hypothetical, but anything is possible. And then comes the part i am asking: non greediness
take care of that, and it should be perfect sed solution

I know we can substitute a string using sed but how?
For example: sed 's/(old variable)/(new variable)/ details.dat
Am I suppose to put $old variable or whatever? Because I tried many times, it didnt work by putting $old variable. Am I suppose to enclose it with "" or ''?

I have a file with some numbers having single quotes around them which I want to remove.
i.e. '923930' -> 23930
