# function zfcd {
|
|
# zfcd: change directory on the remote server.
|
|
#
|
|
# Currently has the following features:
|
|
# --- an initial string matching $HOME in the directory is turned back into ~
|
|
# to be re-interpreted by the remote server.
|
|
# --- zfcd with no arguments changes directory to '~'
|
|
# --- `zfcd old new' and `zfcd -' work analagously to cd
|
|
# --- if the connection is not currently open, it will try to
|
|
# re-open it with the stored parameters as set by zfopen.
|
|
# If the connection timed out, however, it won't know until
|
|
# too late. In that case, just try the same zfcd command again
|
|
# (but now `zfcd -' and `zfcd old new' won't work).
|
|
|
|
# hack: if directory begins with $HOME, turn it back into ~
|
|
# there are two reasons for this:
|
|
# first, a ~ on the command line gets expanded even with noglob.
|
|
# (I suppose this is correct, but I wouldn't like to swear to it.)
|
|
# second, we can no do 'zfcd $PWD' and the like, and that will
|
|
# work just as long as the directory structures under the home match.
