CRITICAL:root:unknown notebook: None
Error, notebook must be one of default, ipython, sagenb but got None
It seems that the problem is with the "-n" part of a-n.tex
it's a bug or a feature ?

https://ask.sagemath.org/question/25624/sagetex-hyphen-in-filename-forbidden/?comment=25625#post-id-25625That is really interesting; `-n` is what launches the notebook. What are the names of the particular *Sage* files generated? That is what Sage runs on.Wed, 28 Jan 2015 16:22:15 +0100https://ask.sagemath.org/question/25624/sagetex-hyphen-in-filename-forbidden/?comment=25625#post-id-25625Comment by slelievre for <p>I want to cross-compile (pdflatex + sage + pdflatex) a TeX file : it's ok with the filename "a-b.tex", but not for a-n.tex, where i get the error message</p>

https://ask.sagemath.org/question/25624/sagetex-hyphen-in-filename-forbidden/?comment=25627#post-id-25627I confirm that: I copied sagetex's example file "example.tex" with the name "a-n.tex", ran "pdflatex a-n.tex", then "sage a-n.sagetex.sage" and Sage gives the same error message.Wed, 28 Jan 2015 16:57:43 +0100https://ask.sagemath.org/question/25624/sagetex-hyphen-in-filename-forbidden/?comment=25627#post-id-25627Answer by tmonteil for <p>I want to cross-compile (pdflatex + sage + pdflatex) a TeX file : it's ok with the filename "a-b.tex", but not for a-n.tex, where i get the error message</p>

https://ask.sagemath.org/question/25624/sagetex-hyphen-in-filename-forbidden/?answer=25628#post-id-25628This is a bug, thanks for reporting. On the file `src/bin/sage`, there is a condition:
if [[ "$1" =~ "--notebook="* || "$1" =~ "-n="* || "$1" =~ "-notebook="* ]]; then
sage-cleaner &>/dev/null &
exec sage-notebook "$@"
fi
The problem is that it is accepted if `-n` is part of the variable `$1`, not only a prefix, as you can check with:
$ A='aze-naze'
$ if [[ "$A" =~ "-n="* ]] ; then echo hop ; fi
hop
A better solution would be to add a `^` to specify the beginning of the string and use `.*` instead of `*`:
$ A='aze-n=aze'
$ if [[ $A =~ ^-n=.* ]] ; then echo hop ; fi
$ A='-naze'
$ if [[ $A =~ ^-n=.* ]] ; then echo hop ; fi
$ A='-n=aze'
$ if [[ $A =~ ^-n=.* ]] ; then echo hop ; fi
hop
It is reported as [trac ticket 17685](http://trac.sagemath.org/ticket/17685).
