tSystem Component - Unix cmd issue

rommy — Sat, 16 Nov 2024 01:06:55 GMT

Hi All,

I am trying to use unix rm command in t system component to remove the previous files, but its not working , I am using following line for cmd to run on unix box.

single cmd

"rm "+context.dir+"/file_loc/load*"

to remove all files starting with load, I dnt want to use get file list and other components to delete files, Can someone tell me what I am doing wrong ?

I tried with

"cmd /c"+context.dir+"/file_loc/load*" >> this failed too in a single cmd.

Thank you !

Hello ,

Your command must be:

new String[]{"/bin/bash","-c","rm"+context.dir+"/file_loc/load*"}

here, the difficulty where not the context.dir, but the * character at the end because it's a special character

cmd /c is for windows

For inbuild command on linux it's bash -c

You can also set an array of command with all the elements of the command string. More information aboiut special character usage here: https://community.talend.com/s/article/Executing-a-Linux-command-with-a-pipe-using-a-tSystem-component-IOBiH
