Hi,
I try to copy files that match a certain pattern to another dir, i write
cp_r /\/downloads\/bsd/i, "~/biblio/bsd/"
if i can use regex to do this
There's nothing in the standard library docs that suggests you can use a
regex for the src argument. The description of cp_r says:
---
If src is a directory, this method copies all its contents
recursively....
src can be a list of files.
---
It doesn't say src can be a regex and that ruby will search your entire
hard drive for matching directories.
what is wrong in my approach?
I can't get cp_r to work when providing multiple directories as the
source, for example:
cp_r(%w{./dir1 ./dir2}, "./test_dir")
produces this error:
/usr/lib/ruby/1.8/fileutils.rb:475:in `mkdir': No such file or directory
- /blah/blah/dir1/test_dir/dir1 (Errno::ENOENT)
where dir1 is the current working directory.
A solution would be to use Dir.glob() to search your hard drive for
matching directories, for instance:
arr = Dir.glob("/downloads/bsd", File::FNM_CASEFOLD)
and then step through the array using each(), and then call cp_r() on
each directory.
