There are two lines in the rpm2targz script which cause errors on g/fbsd due to their incompatibility with fbsd's sh: 1] line 26 -> [ "$TMPDIR" == "" ] && TMPDIR=/tmp The correct expression, compatibile with the sh syntax, is with only one equal sign, so: [ "$TMPDIR" = "" ] && TMPDIR=/tmp 2] line 91 -> if echo ${PAYLOADHEAD} | grep -e $'^\037\213' > /dev/null ; then This line fails due to the fact that the $'' construct is unsupported, as noted by exg, and therefore grep interprets \037 and \213 as backward expressions, instead of the considering the respective non-printable characters (which are the magic bytes of the gzip format). A possibile solution could be to filter PAYLOADHEAD trough `od -c` and then simply: grep -e '037.213' However as Flameeyes noted, the most simple (yet effective) solution is to use bash instead of sh to parse the script. Reproducible: Always Steps to Reproduce:
I have committed the fix; as with the new baselayout we might have more people having /bin/sh not linked to bash, I've followed exg's suggestion and used od -c.
