# function zfrglob {

# Do the remote globbing for zfput, etc.
|
|
# We have two choices:
|
|
# (1) Get the entire file list and match it one by one
|
|
# locally against the pattern.
|
|
# Causes problems if we are globbing directories (rare, presumably).
|
|
# But: we can cache the current directory, which
|
|
# we need for completion anyway. Works on any OS if you
|
|
# stick with a single directory. This is the default.
|
|
# (2) Use remote globbing, i.e. pass it to ls at the site.
|
|
# Faster, but only works with UNIX, and only basic globbing.
|
|
# We do this if $zfrglob is non-null.
|
|
|
|
# There is only one argument, the variable containing the
|
|
# pattern to be globbed. We set this back to an array containing
|
|
# all the matches.
