 Dear Ealeal, 
The MESA docs have a search feature which will bring you to the following: 
https://docs.mesastar.org/en/release-r21.12.1/reference/env_vars.html?highlight=MESA_SKIP_OPTIONAL

There you can see that MESA_SKIP_OPTIONAL only pertains to the test suite, so users generally don't need to worry about it. 
The rest is standard bash. You can see their meanings for example in this bash tutorial: 
https://tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_01.html

Best wishes, Earl

Dear  Mesa users,

I amgetting into MESA 15140, and I see that running the inlists as module is an important part of it.
I tried understandingwhat the “-n” and “-z” mean (highlighted below)  in the rnfile, and I could not find what is there meaning in MESA or in Fortran, Also I am not sure what is $MESA_SKIP_OPTIONAL" is this a parameter? I amsurely missing something , and I appreciate the help.
Here is thecode:

This is takenfrom test_suite/pisn/rn:

++++++++++++

if [ -n"$MESA_SKIP_OPTIONAL" ]; then

   cp standard_late_pre_zams.modlate_pre_zams.mod

else

   do_one inlist_make_late_pre_zams_headerlate_pre_zams.mod

   cp late_pre_zams.modstandard_late_pre_zams.mod

fi

+++++++++++++

This istaken from  test_suite/1M_pre_ms_to_wd

 

if [ -z"$MESA_RUN_OPTIONAL" ]; then

   cp standard_start_he_core_flash.modstart_he_core_flash.mod

else

   do_one inlist_to_start_he_core_flash_headerstart_he_core_flash.mod LOGS_to_start_he_core_flash

   cp start_he_core_flash.modstandard_start_he_core_flash.mod

fi

+++++++++++++++

 

If there isa general explanation to all these modes, it will be great.

Thanks alot,
Ealeal_______________________________________________
