Glob and Regular Expressions


Shells expand stars and question marks ("wildcards")
Applications see names after expansion (be careful about no match!)
The command line can be very long (*very* long)
This expansion is called "globbing"

But glob expressions are not regular expressions
they are simpler
they are much less powerful

If you need to pass special characters to commands:
You can prefix with backslash
You can use single quotes
You can use double quotes
Single quotes preserve '$', double quotes expand variables
