Redirect data to a file using echo in tSystem component

WSyahirah21 — Fri, 15 Nov 2024 23:14:00 GMT

I need to run an echo command to redirect data into a file using echo in text. I know I can use bash or python script to do so. however, that is impossible so far as the destination file is defined from context section in Talend.

My command is :

"echo 'Full Refresh Ingestion' " + ">>" + context.textfile

However, the output only print out back the command I created -> Full Refresh Ingestion >> /path/ingest.txt

Is there any way I could do to save the statement I declare into a file that is already defined in Contexts, using tSystem component?

Please assist, thanks

I try this command using tSystem on Windows and it works.

"cmd /c echo HELLO >> "+context.filepath

I tried the command on Linux and it does not work on Linux.

"echo HELLO >> "+context.filepath

Try another way to log the output to a file, select ' standard output' on tSystem to global variable, and then output the value of global variable to file.
