checking for existing files in bash

[nandasunu]

hi, I am trying to write a small shell script in bash and need to be able to check if a given file exists. I am not new to programming, but new to linux. Is there such a function that would return 1/0 if a file name exists for example?

any suggestions would be much appreciated.
