Short description: All comands sent to server in batch mode are being echoed back along with prompt. Software Version: "OpenSSH_7.9p1, OpenSSL 1.1.1 11 Sep 2018" (as printed by ssh -V) Server and client systems: ArchLinux x86_64 fully updated as of 2018-11-02. ## How to reproduce Provided that you have proper SSH key authentication in place, from command line run: echo "dir /var" | sftp -b - 0 ## Expected output /var/backups /var/cache /var/lib /var/local /var/lock /var/log /var/mail /var/opt /var/puppet /var/run /var/spool /var/tmp /var/www ## Actual output sftp> dir /var /var/backups /var/cache /var/lib /var/local /var/lock /var/log /var/mail /var/opt /var/puppet /var/run /var/spool /var/tmp /var/www Please note the first line is the server prompt followed by the command echo. ## Workaround Expunge the first line from the client output echo "dir /var" | sftp -b - 0 | tail -n +2 ## Notes Batch mode is meant for script automation, not human operations, so echoing the prompt and the commands doesn't make any sense and creates problems while processing the output. A possible solution that's also backward compatible with all scripts using 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 client. Something like "@" or "#" would be ok IMHO. -- Vincenzo Romano - NotOrAnd.IT Information Technologies -- NON QVIETIS MARIBVS NAVTA PERITVS _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
