Adding parentheses to directory structure when using bin

[avsastry]

Bug report

Expected behavior and actual behavior

I'm currently working within a Dropbox folder that is auto-named as "Dropbox (UCSD)". The presence of these parentheses seem to be properly accounted for in all cases, except when I'm trying to run a script from the "bin" folder. In the .command.run file, I see the following code:

nxf_container_env() {
cat << EOF 
export PATH="/home/anand/Dropbox (UCSD)/Projects/nextflow_test/bin:\$PATH"
EOF
}

It seems that the export call to use the "bin" directory doesn't backslash the parentheses and the spaces, resulting in a run error:

  /bin/bash: eval: line 0: syntax error near unexpected token `('
  /bin/bash: eval: line 0: `export PATH=/home/anand/Dropbox (UCSD)/Projects/nextflow_test/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'

Steps to reproduce the problem

I can attach a working version if necessary

Same bug for me. Any update on it?

[bentsherman]

Maybe the bin path should be escaped with Escape.path() in addition to Escape.variable():

nextflow/modules/nextflow/src/main/groovy/nextflow/processor/TaskProcessor.groovy

Lines 2090 to 2091 in 2fb5bc0

	// escape both wrapping double quotes and the dollar var placeholder
	script << /export $name="${Escape.variable(value)}"/

Thanks @bentsherman, these headaches are all caused by the stupid decision made by the Dropbox team to include spaces in folder names. The solution (link below) provided by rwmorris solves the headache. Hope it helps someone else.

@bentsherman worth to give a try to it
