Re: Can python quickly display results like bash?
thank you, it works with -m trace. As to sh -x, it is used to expand the variables of command, and display it before executing. $ info bash * The `-x' (`xtrace') option displays commands other than simple commands when performing an execution trace (*note The Set Builtin::). 2009/3/18 Chris Rebert : > On Tue, Mar 17, 2009 at 11:13 AM, D'Arcy J.M.

Ah. This is what I get for using Preview to view manpages. It used actual unicode hyphens, thus screwing up my search.

On my system the OPTIONS section of bash(1) begins with: In addition to the single-character shell options documented in the description of the set builtin command, bash interprets the following options when it is invoked: [...] set [--abefhkmnptuvxBCHP] [-o option] [arg ...] [...] -x After expanding each simple command, for command, case command, select command, or arithmetic for command, display the expanded value of PS4, followed by the command and its expanded arguments or associated word list. -- http://mail.python.org/mailman/listinfo/python-list

Check the man page for sh > (1) for a description. Ah, I should've thought to google for the sh manpage. Locally, man sh just gives me the bash manpage again which doesn't list -x :-( In answer to the OP's question, you can use the `trace` module (http://docs.python.org/library/trace.html): python -m trace -t somefile.py will display the lines of source as they are executed.

I've read the manpage for bash and can find no such -x option listed. And this term is nigh impossible to google for, so that didn't turn anything up. What exactly does the -x option to bash do? Where is it documented? Cheers, Chris -- I have a blog: http://blog.rebertia.com -- http://mail.python.org/mailman/listinfo/python-list
