FTP with No-OverWrite

[panchpan]

Hello.
I would like to ftp files from one HP-UX machine to another HP-UX machine. But on destination already many files are present. Is there a way to FTP files with no-overwrite option?

Thank you!

No. Unless destination files have no write perms.

How to make destination files as no-overwrite?

[RAC_1]

Every file on unix has three permissions associated with it. red, write and execute.

To make file un-writable.
chmod ugo-w
man chmod for details.

Many Thanks.
Also, can you please tell me the command of copying or modifying 100 files as filename.old ?

thanks

Hi,
you may need to use the chmod 444 filename, rather than ogu. You should get a "555 Permission denied".

Example of renaming of files:
for i in `ls *.txt`
do
echo mv $i ${i}.old
done

Once you are happy with the output, remove the echo.
