Is it possible to call a tezos-client binary from within a programming language? I have been trying to achieve this, but without success. The very same command used through the command line works, but when I call it from a script, it fails.

I've seen some advice to write the command inside a shell script, like test.sh. I did this and the script only works in the command line. If I call it from within a program, it fails too.

Is this a security measure of tezos-client? Or is there a correct way to do it?

This is the command I want to call in my software:

tezos-client transfer 1 from myAlias to tz1.... --fee 0.05 --dry-run

    Please report the error message you say otherwise it is unclear what is your problem – Ezy♦ Feb 11 '19 at 2:13

Try to be as explicit as possible:

  • specify the full path to tezos-client
  • specify the absolute directory containing the data, especially the aliases (generally --base-dir /home/[..USER..]/.tezos-client)

If it does not work, copy-paste the error messages, so that we can understand the problem.

  • This solved the problem. After I've added --base-dir /home/user/tezos/.tezos-client to the transfer command, it worked flawlessly. A sample functional command would be like this: /home/user/tezos/tezos-client --base-dir /home/user/.tezos-client transfer 1 from myAlias to tz1.... --fee 0.05 --dry-run – Luiz Milfont Feb 11 '19 at 23:41

Try the full path. Like that:

home/your_user_name/tezos/tezos-client transfer 1 from myAlias to tz1.... --fee 0.05 --dry-run

  • I've already tried full path and there is no difference. It works on cmd line, but fails if called inside a program. Tezos-client returns a message saying it does not recognize the alias. – Luiz Milfont Feb 11 '19 at 0:00
  • Check the user your script is running as. It sounds like it may not be the one you think it is. – xtzbaker Feb 11 '19 at 6:12

    The full path is important, but what was really missing was the --base-dir parameter. Anyways, thank you a lot. – Luiz Milfont Feb 11 '19 at 23:46
