Bug ID: 2926
Summary: In batch mode sftp echoes the prompt and the commands
back
Product: Portable OpenSSH
Version: 7.7p1
Hardware: amd64
OS: Linux
Status: NEW
Severity: enhancement
Priority: P5
Component: sftp
Assignee: [email protected]
Reporter: [email protected]
Batch mode is meant for script automation, not human operations, so
echoing the prompt and the commands doesn't make any sense and needs
extra stuff while programatically processing the output
A possible solution that's also backward compatible with all uses of
the batch mode is to allow for a special prefix character to commands
to avoid any echoing, just like the "-" is used to avoid a single
failing command to terminate the session.
Something like "@" or "#" would be ok IMHO.
For example, the command syntax could become:
[@][-]<command> [arguments]...
The current workaround is to expunge every first output line, but am
not sure whether this can apply to all use cases.
