Different behavior between bash shell and bash script for cmd
So I'm trying to pass certain json elements as env vars and use them later on in a script.


Sample json:
Code:
JSON='{  
    "Element1": "file-123456",
    "Element2": "Name, of, company written in, a very weird way",
    "Element3": "path/to/some/file.txt",
}'


(part of the) script:
Code:
for s in $(echo $JSON | jq "{Element1,Element2,Element3} | to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]");do
export $s
done


The problem I'm having is that Element2 is breaking the line when exporting but if I just run "echo $JSON | jq "{Element1,Element2,Element3} | to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]"" at the cmd line, it looks fine:
Code:
"Element1=file-123456"
    "Element2=Name, of, company written in, a very weird way"
    "Element3=path/to/some/file.txt"


Actual output of script:
Code:
1.bash: line 100: export: `of,': not a valid identifier
1.bash: line 100: export: `company,': not a valid identifier
1.bash: line 100: export: `written,': not a valid identifier


As can be seen, the export command inserts single quotes into the "Element2" and I'm not sure where they come from.


The second variable (Element2) only contains the first element in the string (Name,). The behavior makes sense since the line is broken but for the life in me I cannot understand how or why the export command inserts them.


Any insight is appreciated, thank you!

xsil2graphics

XSIL2GRAPHICS(1)					User Contributed Perl Documentation					  XSIL2GRAPHICS(1)

NAME

       xsil2graphics - generate scripts to load xsil output data files

SYNOPSIS

       xsil2graphics [options] <xsil_file>

DESCRIPTION

       Utility program bundled with xmds, used to generate scripts that load simulation output data into either matlab (http://www.mathworks.com)
       or scilab (http://www.scilab.org), which are then used to manipulate the results further if necessary and then to present the results
       graphically.

       Matlab

       To generate a matlab m-file, from the xsil file data_file.xsil use the command:

       bash$ xsil2graphics data_file.xsil

       or

       bash$ xsil2graphics --matlab data_file.xsil

       Then at the matlab command prompt:

       >> data_file

       Scilab

       To generate a scilab script file, from the xsil file data_file.xsil use the command:

       bash$ xsil2graphics --scilab data_file.xsil

       Then at the scilab command prompt:

       --> exec('data_file.sci')

OPTIONS

       -m, --matlab generate matlab m-file script to load data from the xsil data file (the default option)

       -s, -scilab generate scilab script file to load data from the xsil data file

       -o, --outfile <out_file> specify an alternative output script filename to the default which is the input xsil filename with the .xsil
       extension changed to either .m for the matlab m-file or .sci for the scilab script file

EXAMPLES

       bash$ xsil2graphics nlse.xsil

       Generates the output nlse.m to load the data into matlab

       bash$ xsil2graphics -m nlse.xsil

       Also generates the output nlse.m but explicitly sets matlab to be the output format

       bash$ xsil2graphics --scilab nlse.xsil

       Generates the output nlse.sci to load the data into scilab

       bash$ xsil2graphics --outfile nlse_new.m nlse.xsil

       Generates the output nlse_new.m to load the data into matlab
