Bash has a syntax for manipulating variables as seen in this page. Examples:

  • ${foo:0:2} -> `foo.substr(0, 2)
  • ${foo#hello} -> remove leading "hello"
  • ${foo%world} -> remove trailing "world"
  • ${foo/abc/xyz} -> foo.replace('abc', 'xyz')
  • ${foo//abc/xyz} -> foo.replace(/abc/g, 'xyz')
  • and many more useful cases...
