grep - multiple positions
I was wondering if anybody can help me with this. I have the following code to look for a space in position #48 and I want to change it so it looks in position 48, 59, and 50 for spaces. How can I do that?

Here's the current code -
grep -v '^.\{48\}[[:space:]].*' <infile> > <outfile>

Any help would be appreciated.
