Re: [Modules] How to set-env with multi line content

[Paul M. <pau...@gm...>]

You might want to surround that code to make sure it is only run for bash.

if { [module-info shell bash] } {
	puts stdout "export FOO='my\nmulti\nline\nvalue';"
}


Note:
The real sh (bourne shell) doesn't allow export to set values inline.
However, on linux, sh is actually bash (usually).

This shows me that the module load must outputting a string to bash that is only setting the first line of the file to the variable FOO, then the subsequent file lines are getting dropped right to bash to evaluate.
