Re: [Bashdb-help] bashdb syntax error with for loop

[Rob W. <rcw...@gm...>]

Hi Rocky,

That's great news!

I've seen comments about complications with building bashdb correctly so
I'll be a little explicit in what I tested:

I cloned the git repo.  Then ran ./autogen.sh and make.

Then used "./bashdb -L . /tmp/bashdb_test.sh" to debug my script from within
the top-level of my git clone.

The testcase I provided passed without any problems.  Originally the problem
I saw used: "for i in $foo" with foo="/path" so I tested that too.  That
worked perfectly as well.

Thanks,
Rob
