I have been trying to capture bash pipe errors as follows:
ret1=0; ret2=0; ret3=0; ret4=0; ret5=0
out=$(\ grep "PATTERN" "${SFILE}"; ret1=$? 2>&1 | \ sed $re1 $re2; ret2=$? 2>&1 | \ sort -n; ret3=$? 2>&1 | \ uniq >> "${TFILE}"; ret4=$? 2>&1\ ); ret5=$?
But the return status variables are not changed should any command errors arise.
How could one go about capturing command errors within pipes?
Thanks! Dan
