Script to cd into newest (dated) FTP directory
I have written the following simple bash script. It logs onto an FTP site and then CDs into a directory that corresponds to the last business day. So for example the directory I would access today is 20060110 (2006 jan 10).

I am currently taking today's date and subtracting 1, putting this into a variable and then entering ftp mode, cd'ing to the directory (in the variable) and downloading the file (always same filename). This obviously does not work for weekends and holidays, as subtracing 1 on monday would give sunday. There are no directories created on weekends and holidays.

My two ideas to rectify this are 1) do something complex to figure out the last business day before entering ftp mode or 2) figure out how to CD into the newest directory, regardless of its name (the newest directory will always be the previous day).

Any ideas are appreciated here. Maybe there is a much easier way to do this that I am not considering?

Thanks in advance for any help, this is my first post.

mydate=$(date +%F | tr -d [:punct:])
let prevdate=$mydate-1
user='xxxxxxx'
pass='xxxxx'

ftp -n ftp.xxxxxxx.com << ENDEND
passive
user xxxxx xxxxx
hash
cd $prevdate
get POA_133_Position.csv
quit
ENDEND
echo "Done."
exit 0

FTPUSERS(5)						     Linux Programmer's Manual						       FTPUSERS(5)

NAME

       ftpusers - list of users that may not log in via the FTP daemon

DESCRIPTION

       The  text  file	ftpusers  contains a list of users that may not log in using the File Transfer Protocol (FTP) server daemon.  This file is
       used not merely for system administration purposes but for improving security within a TCP/IP networked	environment.   It  will  typically
       contain	a  list  of  the  users that either have no business using ftp or have too many privileges to be allowed to log in through the FTP
       server daemon.  Such users usually include root, daemon, bin, uucp, and news.  If your FTP server daemon doesn't use ftpusers  then  it	is
       suggested  that	you  read  its	documentation  to find out how to block access for certain users.  Washington University FTP server Daemon
       (wuftpd) and Professional FTP Daemon (proftpd) are known to make use of ftpusers.

   Format
       The format of ftpusers is very simple.  There is one account name (or username) per line.  Lines starting with a # are ignored.

FILES

       /etc/ftpusers

SEE ALSO

       passwd(5), proftpd(8), wuftpd(8)
