ftp script help

[lawrenzo]

Hello,

I am writing an ftp script for the first time .......

I am familiar with the syntax ie

ftp -v -i -n <

Chris,
the way I see it:

1. To check you have all the info of the file, get a list of the directory you are ftping, then ftp the files and compare the size of the files against the dir listing.

That assumes you can't get the source system to generate an index file with checksum of all the individual files, which would act as a marker that all the files had been generated on the source - clear to start ftp.
You could then use the checksum file to compare checksums.

Header/trailer records could be an alternative.

2. use "get abc _abc"

then after comming out of the ftp part of the script move _abc to abc


What do you think ?

good idea however I am putting the files to a windows box then moving to an archive dir on the unix box.

the files are _abc when ftp puts to the windows box then rename _abc abc on the windows box so another program can then transfer to a server else where.

on the unix box then mv the abc to /archive.

I have an idea where I list the files on the unix server and create a files.lst.

files ftp over then ftp the files.lst then run a program on the windows server to xref _abc with files.lst.

once verified mv files within files.lst to archive.

a bit of a mess but we are using an sftp server for transfering data to a company not associated with the company I work for.

is there a way I can reference files.lst so to ftp the files in that list?

Chris.

Chris,
best way for referencing is to do a dynamic ftp script:
echo "ftp -v -i -n < ftper.sh
echo "username xxxxx xxxx" >>ftper.sh
# prefix each file with "get "
sed "1,$ s/^/get /" files.lst > files.dat
cat files.dat >> ftper.sh
echo "quit" >> ftper.sh
echo "!EOF" >> ftper.sh
chmod 777 ftper.sh
./ftper.sh

one thing so I understand the syntax etc what does:

sed "1,$ s/^/get /" files.lst > files.dat

the "1,$" mean? I get the s/^ is the start of the line - does it mean from beginning to end of file?

cheers

Chris,
yes, 1 to last line

>lawrenzo what does: the "1,$" mean?

You should probably remove it since that's the default. And you would probably understand it better. :-) (For vi/ex, you can use % for that.)
