macOS grep question

[Big Dave]

I need some help with syntax.

I would like to do the following:

grep text$imoretext

where $i is a variable

I can't figure out how to make this one work. Any ideas?

Thanks,

Dave

Do you mean "where $i is a shell variable"?

If so:

grep "text${i}moretext"

This question has nothing to do with grep itself. It's about how to delimit shell-variable names so they don't combine with adjacent literal text. See the "Parameter Expansion" subsection of the bash man page:
