copyDirectory(String,String)

Synopsis

Usage:
copyDirectory(src,dst)
Function: copyDirectory
Inputs:
- src, a string
- dst, a string
Consequences:
- a copy of the directory tree rooted at src is created, rooted at dst
Optional inputs:
- Exclude => default value {}, a string containing a regular expression, or a list of such strings. If the base part of the name of a file in the source tree matches one of the regular expressions, then no link to it is created
- UpdateOnly => a Boolean value, default value false, whether to copy files only if the target file does not exist or is older than the source file
- FollowLinks => a Boolean value, default value false, whether to follow symbolic links in the source tree to directories
- Verbose => a Boolean value, default value false, whether to report individual file operations

i13 : get (dst|"b/c/g")

o13 = ho there

Now we remove the files and directories we created.

i14 : rm = d -> if isDirectory d then removeDirectory d else removeFile d

o14 = rm

o14 : FunctionClosure

i15 : scan(reverse findFiles src, rm)

i16 : scan(reverse findFiles dst, rm)
