I want to check if a file exists by using a if comparison for a base path concatenated with a file name. I'm trying things like:

declare -r BasePath="/some/path"

if [ -f "$BasePath" "/my_file.txt" ]
then
    #do something
fi

I just can't get the concatenation of the variable holding the base path with the string literal to work within the comparison.

Just:

if [ -f "$BasePath/my_file.txt" ]
