need help Greping "$size[0]"
Hello

I want to grep "$size[0]" how can I comment out the "[]" so it actually searches for the full thing and not 0?

Thank You

If you are using bash and want to grep for all elements of the array at once, you should use syntax like:
Code:
grep ${size[*]}

If you want to grep only for a single element of that array:
Code:
grep ${size[0]}

If you want to check for each element of that array, you have to increase the index in the brackets by 1 inside some loop, for, while, whatever.

Do you mean as a text literal?
Code:
grep 'size\[0\]'

zaxxon did a fine job with searching for arrays
