I am using storescp.exe(http://support.dcmtk.org/docs/storescp.html) as StoreSCP of my DICOM application. I need to send the DICOM files to storescp where no dcm file is generated. Could you please inform the switch statement for preventing file generation on store operation?
The command line option is --ignore
storescp --ignore

I have a very big file that has to be transferred to a remote server.
On that remote server there is a job activating each 5 min that, once sees a file name starting with the right prefix, processes it.
What happens if the job "wakes up" in the middle of transfer? In that case it would process a corrupted file.
Do pscp create a .temp file and renames it accordingly to account for that? Or do I have to handle this manually?
No pscp does not transfer the files via a temporary file.
You would have to use another SFTP client – If you use pscp as SFTP client. The pscp defaults to SFTP, but it falls back to SCP, if SFTP is not available. If you need to use SCP (what is rare), you cannot do this, as SCP protocol does not support file rename.
Either an SFTP client that at least supports file rename – Upload explicitly to a temporary file name and rename afterwards. For that you can use psftp from PuTTY package, with its put and mv commands:
open user#hostname
put C:\source\path\file.zip /destination/path/file.tmp
mv /destination/path/file.tmp /destination/path/file.zip
exit
Or use an SFTP client that can upload a files via a temporary file automatically. For example WinSCP can do that. By default it does for files over 100 KB only. If your files are smaller, you can configure it to do it for all files using the -resumesupport switch.
An example batch file that forces an upload of a file via a temporary file:
"C:\Program Files (x86)\WinSCP\WinSCP.com" ^
/log="C:\writable\path\to\log\WinSCP.log" /ini=nul ^
/command ^
"open sftp://username:password#example.com/ -hostkey=""ssh-ed25519 255 ...=""" ^
"put -resumesupport=on C:\source\path\file.zip /destination/path/" ^
"exit"
The code was generated by WinSCP GUI with the "Transfer to temporary filename" options set to "All files".

I know using rsync -c we can copy files and having them verified with checksum. The issue is that rsync first build a list of files and at the same time it computes the checksum for all files. This would take forever if you have millions of files. Is there a solution where the checksum is simply computed as the application reads the file streams for the copy task?
This should be the default behaviour for rsync since 3.0.0, assuming that you don't have all the files in one directory.
However, there are some options that force rsync to scan all the files up front; look at the man page and search for "incremental" for more details.
TLDR; Convert the bash line to download sftp files get Inbox/* to c++ or python. We do not have execute permissions on Inbox directory.
I am trying to read the files present in a directory in a remote server through SFTP. The catch is that I only had read and write permissions on the directory and not execute. This means any method that requires opening (cding) into the folder would fail. I need to read the file names since they are variable. From what I understand ls does not require execute privs. If I can get a list of files in the directory then reading then would be fine. Here is the directory structure:
Inbox
--file-a.txt
--file_b.txt
...
I have tried libssh but sftp_readdir required a handle of the open directory. I also looked at paramiko for python but that too requires to open the directory to read the file names.
I am able to do this in bash using send "get Inbox/* ${destination_dir}". Is there anyway I can use a similar pattern match but on c++ or python?
Also, I cannot execute bash commands through my binary. Does anyone know of any library in python or c++ (preferred) that would support this?
I have not posted here in a while so please excuse me if I am not following the formatting. I will learn from your suggestions. Thank you!
When I am doing cp -R at my system
cp -R \[Bark\]\ Java/ /Volumes/Seagate\ Backup\ Plus\ Drive/
its throwing this message
cp: /Volumes/Seagate Backup Plus Drive/Advanced: Read-only file system
cp: [Bark] Java//Advanced:unable to copy extended attributes to /Volumes/Seagate Backup Plus Drive/Advanced: Read-only file system.
I guess I need to make the backup disk in write mode
How to change the mode of the backup disk.
Mounting on many UNIX systems is controlled by the etc/fstab file (see here). This usually specifies mount options for each device.
You need to change the mount options for the device you're interested in.
If you examine the /etc/fstab file on your system, you should see something along the lines of ro in the options column.
If you change that to rw and then remount it, it should be writeable.
You may want to change it back when you're done so as to protect the information on it.
For Mac OSX, fstab is still used but the file systems may also be under the control of automount - look up the man pages for automount and autofs.conf for information on how to configure those.
rsync creates a temporary hidden file during a transfer, but the file is renamed when the transfer is complete. I would like to rsync files without creating a hidden file.
alvits is correct, --inplace will fix this for you. I found this when I had issues syncing music to my phone (mounted on ubuntu with jmtpfs). I would get a string of errors renaming the temporary files to replace existing files.
