Upload files using SFTP or SCP commands

Upload a file using SFTP or SCP commands

Use the SFTP or SCP client of your choice. Click "Enter/Return" on your keyboard after each command.

 Note: Commands are case-sensitive and all alphabetic characters must be lowercase.

Verify a file has been uploaded successfully

Almost immediately after a file upload completes, the system moves the file into a queue for subsequent processing and it is no longer available on the upload server.  The only reliable way to verify the success of the upload is to check for a non-zero condition code or for error messages after the upload attempt.

The following is an example of a script that checks for a non-zero return code. This assumes the bash shell is in use, which is the default on most Linux distributions:

#!/bin/bash

# This script assumes that a public / private key pair has been setup already between the
# client account that is running the script on the local machine and the fx_zzzzz server
# account on OCLC's filex-m1.oclc.org host

sftp -v fx_zzzzz@filex-m1.oclc.org <<EOF
lcd /zzzzz/bib/xfer/out/
cd /xfer/metacoll/in/bib/
put 1234567.zzzzz.bibs.20200101.mrc
quit
EOF

# Best practice is to assign the sftp return code to a variable for further use, because
# ${?} is fleeting and only shows the condition code of the immediately preceding command

SFTP_RETURN_CODE=${?}

# If the return code is non-zero then the upload was not successful

if [[ 0 != ${SFTP_RETURN_CODE} ]]
   then
   echo "bib upload for zzzzz failed"
   exit ${SFTP_RETURN_CODE}
else
   echo "bib upload for zzzzz was successful"
fi

exit 0
