Display executed command is broken on file concatenation

[antonkomarev]

Command:

(set -x; cat ${OUTPUT_SERVER_CERTIFICATE} ${CA_CERTIFICATE} ${OUTPUT_SERVER_PRIVATE_KEY} > "${CERTIFICATE_CHAIN}")

Expected Output:

+ cat ./output/localhost.crt /usr/local/share/ca-certificates/!pric/ca.crt ./output/localhost.key > ~/localhost-certificate.pem

Actual Output:

+ cat ./output/localhost.crt /usr/local/share/ca-certificates/!pric/ca.crt ./output/localhost.key

To test it you could create a test file issue-9.sh:

echo "(set -x; cat /etc/hosts > /dev/null)" > issue-9.sh

And execute it:

sh issue-9.sh

Expected output:

+ cat /etc/hosts > /dev/null

Actual output:

+ cat /etc/hosts

There are possible workarounds, but I don't have enough time to dive deep and learn shell even more. So I made the simplest solution - just duplicated and echoed console command.

echo "+ cat ${OUTPUT_SERVER_CERTIFICATE} ${CA_CERTIFICATE} ${OUTPUT_SERVER_PRIVATE_KEY} > \"${CERTIFICATE_CHAIN}\""
cat ${OUTPUT_SERVER_CERTIFICATE} ${CA_CERTIFICATE} ${OUTPUT_SERVER_PRIVATE_KEY} > "${CERTIFICATE_CHAIN}"
