Inside "" we have 1s make a find replace in first line ^(\#!.* )python$$ Is a regexp matching what to be replaced: #!/usr/bin/env python In detail: ^ matches start of line () marks a group \#!.* matches /usr/bin/env (ending with a space) python matches python! $ matches end of line. I think this could be the error as the line only ends once \1 -S PYTHONPATH=${DATADIR} ${PYTHON_CMD} This is what the previous expression is replaced with: \1 puts what was in the group () from first regexp e.g. #!/usr/bin/env The rest is just to set the pythonpath before executing python. I have never seen this though and do not know if it will work Best regards Troels Kofoed Jacobsen chu...@telenix.org > > should be only a single space between ${DATADIR} and ${PYTHON_CMD}, my mailer > put a line break in there for me ... > > If you care, this came from editors/spe/Makefile. > _______________________________________________ > freebsd-ports@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-ports > To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org" _______________________________________________ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
