Hands on the filepath Library in Golang

filepath.Base

In [2]:
filepath.Base("/usr/local/bin")

bin

filepath.Join

In [2]:
filepath.Join("/usr/", "local/bin")
Out[2]:
/usr/local/bin

filepath.Glob

Note: The glob package in Python and Rust behave similarly. Both of them find all files and subdirectories for the pattern **/*. However, filepath.Glob behaves different from those 2 packages. filepath.Glob treats **/* as */*.
