relativizeFilename -- relativize a file name

Synopsis

• Usage:

  relativizeFilename(dir,fn)

• Inputs:
  • dir, a path to a directory
  • fn, a path to a file
• Outputs:
  • a relativized path, equivalent to fn when starting from dir

Description

i1 : relativizeFilename("a/b/","a/b/c/d")

o1 = c/d

i2 : relativizeFilename("a/b/c/d","a/b/")

o2 = ../../

i3 : relativizeFilename("a/b/c/d","a/b/e/f")

o3 = ../../e/f

Paths of the form foo/x/../bar, are shortened to foo/bar without checking the file system to see whether x is a symbolic link. For the other behavior, see realpath.
