It's definately a bug in the script, not grep: the newer grep is simply reporting what must be a common problem. The script is trying to allow for possible spaces at the beginning of the line, but failing.... with the incorrect regular expression: echo "auto" | grep "^[:space:]*auto" # works auto echo " auto" | grep "^[:space:]*auto" # doesn't work And with the proper regular expression: echo " auto" | grep "^[[:space:]]*auto" # works auto echo "auto" | grep "^[[:space:]]*auto" # works auto Of course it's only going to bite people that have an 'auto' line that starts with spaces but if they do then this problem is will cause them a problem that's very hard to track down!
