Shell Programming and Scripting
1

Am trying a shell script for ftp process on Solaris

I am trying to mget files to

Destination server: myserverxxx1
folder : /backup/dumps/SERVER-1backup/afterbatch

From
Source server: SERVER-1
folder : /dumps/daily/backupafterbatch/Thu21Oct_04:22:37

depending on the date the folder can be
/dumps/daily/backupafterbatch/Fri22Oct_04:25:13
/dumps/daily/backupafterbatch/Sat23Oct_04:25:07

i have to cd to the latest folder

in this case
/dumps/daily/backupafterbatch/Sat23Oct_04:25:07

I am unable to cd to the latest date folder :confused:

my script is as under(## in destination server ## sunftp)
#!/bin/bash
cd backup/dumps/kplusbackup/afterbatch
ftp SERVER-1

I am using .netrc macdef init ,

my .netrc file is as below (## in destination server)

machine SERVER-1 login sunny password sunny12 macdef init
cd /dumps/daily/backupafterbatch
ls -lrt "|tail -1 | cut -c 55-79-exec cd \{} \;"
pwd
ls -lrt

executing the script as under
sunny@mydb1 $ . ./sunftp

output is like

The above command is a (sort of) unix command sequence. It is not a valid ftp command.
The ftp protocol is not Shell and it has a very limited command set.

The only way I know to do this with ftp is with three distinct stages:

1) Use ftp to get a directory list (some versions can sort by timestamp, some can't). Store the directory list in a local file.

2) Process the directory list to find the most recent directory.

3) Use ftp to access that directory and download the files you require.
