Thank you for your explanations, (shell-command-on-region b e "grep -o '\\*[^*]*\\*' > ~/tmp/tmo") worked perfectly (I updated the solution accordingly).

Also, * inside a character class construct [...] is not special and does not have to be escaped. In fact, trying to escape it as you have done, changes the meaning of the character class: "[^\\*]" (the Emacs string form) means any character other than backslash or asterisk. It's always good to remember what JWZ said about regexps, even if you do decide to use them.

Thank you @NickD. I notice something strange: grep -o '\*[^\*]*\*' ~/tmp/tmp.org > test.org works well on a terminal, but from emacs, (shell-command-on-region b e "grep -o '\*[^\*]*\*' > ~/tmp/tm") doesn't...

grep -o '_[^_]*_' /tmp/foo4.org is a start: you only need to get rid of the surrounding underscores. The only problem is the usual one of underscores that are not markup. It should be easy to turn that into an Emacs function (if worse comes to worst, the function can run the grep command, more-or-less as is).
