How to set up a command to run a bash script with variables

When defining the user command, you need to call shell with the -c option and in parenthesis declare the variable name definition followed by a space in the argument to pass to the shell script.

Note

The arguments in the parenthesis need to use the concatenate setting to combine them into a single string to pass to bin/sh -c.

The following is an example script that will echo hello followed by the $(varname) variable value to standard out.

[mmuniz@myserver tmp]$ cat /tmp/hello_variable.sh#!/bin/bashecho helloecho ${varname}

The following user command passes the $(varname) variable definition to the /tmp/hello\_variable.sh script
