sed: illegal option -- r when running bibexport.sh
in [Shell]

From: beatnick on 29 Oct 2006 17:45 Hi, I'm trying to run bibexport.sh on a LaTeX aux file to produce a subsetted .bib file. But when I run ./bibexport.sh it gets as far as creating the new .bib file but doesn't write anything to it. Instead I get the error: sed: illegal option -- r usage: sed script [-Ean] [-i extension] [file ...] sed [-an] [-i extension] [-e script] ... [-f script_file] ... [file ...] Can anyone tell me what I'm doing wrong? I've read the user guide, searched the web etc, am stumped. Many thanks in advance, Nick

You are not doing anything wrong; bibexport.sh is using a non-standard (GNU only?) option to sed. The guide should have mentioned that. -- Chris F.A.

Replace sed with egrep (or grep -E): Change: sed -r -e \ "/^ *[cC][rR][oO][sS][sS][rR][eE][fF] *= *[^,]+,?$/d" \ ${TMPFILE}.bbl >> ${FINALFILE}; To (untested): grep -E -v '^ *[cC][rR][oO][sS][sS][rR][eE][fF] *= *[^,]+,?$' \ ${TMPFILE}.bbl >> ${FINALFILE}; -- Chris F.A.

And you're using a Sun or a Mac perhaps? The offending line seems to be sed -r -e \ "/^ *[cC][rR][oO][sS][sS][rR][eE][fF] *= *[^,]+,?$/d" \ ${TMPFILE}.bbl >> ${FINALFILE}; I'm not enough of an RE hacker to know if that really requires -r or not: try removing the -r and see if it works. ///Peter |
