I could not find any reasonable answer for the following question. (https://www.physicsforums.com/threads/mathematica-output-display.386890/).

I have expressions:

f1=1;
f2=20;

I want to save them in a single file:

PutAppend[f1,f2,"output.m"];

This prints all the expression in the output file. The output of this is:

cat output.m
1
20

However I was wondering is there any way to print (save) the variable name as well or any customised name. The desired output:

f1=1
f2=20

or

name1=1
name2=20

I tried some but those are not useful.

$\begingroup$
foo = {"test"};
bar = Association[];
Save["test.m", {foo, bar}]
FilePrint["test.m"]
foo = {"test"}

bar = <||>

You can Get the symbols back to the current namespace after you have restarted the Kernel or have just removed them once:

ClearAll["Global`*"]
foo
bar
Get["test.m"]
foo
bar
foo

bar

<||>

{"test"}

<||>

  • $\begingroup$ This helps. Save["output.m",f1,f2] will give the desired output, however without customization of the name at the time of printing/saving. Of course one can always change the expression name f1-> name1 and f2-> name2. $\endgroup$
