Variables not getting replaced

2014-01-23 18:46

The log shows that %1% and %2% don't get replaced by the parameters provided. Can you help?

# WINSCP script

# example commandline arguments from mremoteNG
# WinSCP.com"  /script=".\ExternalTools\ssh-copy-id.txt" /parameters "%username%:%password%@%hostname%" ".\ExternalTools\id_rsa.pub" /log=".\ExternalTools\copyssh.log"
# test commandline
# WinSCP.com"  /script=".\ExternalTools\ssh-copy-id.txt" /parameters "example:pwd@domain.com" ".\ExternalTools\id_rsa.pub" /log=".\ExternalTools\copyssh.log"

#Thu January 23, 2014 08:52:23 PM
# not working so far, as the %2% is not getting properly converted somehow


option batch on
option confirm off
open %1%
option transfer binary

call umask 077
call test -d .ssh || mkdir .ssh
put -append %2% .ssh/authorized_keys
close
exit

It's /parameter, not /parameters.

Thanks

Thanks a tons!! Such a stupid mistake on my part.

Another question. The same script, connects to the host 3 times... I don't understand why. Can you explain? Is there a way to connect only once? and instead of supplying the parameter to the script can I just connect via commandline and just execute the script after?

Also I love that you have anonymous posting enabled for infrequent posters!

Anyway see the cleaned logfile below:

Another question. The same script, connects to the host 3 times... I don't understand why. Can you explain?

I see only two connections. The main one and the other one for shell session for call commands:
https://winscp.net/eng/docs/scriptcommand_call

Is there a way to connect only once?

Consider using SCP protocol.

and instead of supplying the parameter to the script can I just connect via commandline and just execute the script after?

Not recommended.

Ok as per your suggestion I changed open to use scp://

but now the put command is overwriting the file instead of just appending to it. as per the documentation here https://winscp.net/eng/docs/scriptcommand_put append only works with sftp. Any workaround for appending to a file with SCP protocol? Maybe echo contents to a pipe ? echo 1.txt >> file.txt where 1 is local and file is remote.

also I see a lot of unalias commands in the log, anyway to suppress that or skip that? It's slowing the script by 21 seconds. I guess this is the startup conversation as the script says.
