Public bug reported:
Binary package hint: grep
grep 2.5.4-4 on Karmic amd64
According to the manual page:
{,m} The preceding item is matched at most m times.
But:
a...@ike:~$ echo 23:45.67 | grep '[0-9]\{,2\}:[0-9]\{2\}\.[0-9]\{2\}'
grep: malformed repeat count
a...@ike:~$ echo 23:45.67 | grep '[0-9]\{0,2\}:[0-9]\{2\}\.[0-9]\{2\}'
23:45.67
a...@ike:~$
With -E, the bug is still there, but reported differently:
a...@ike:~$ echo 23:45.67 | grep -E '[0-9]{,2}:[0-9]{2}\.[0-9]{2}'
a...@ike:~$ echo 23:45.67 | grep -E '[0-9]{0,2}:[0-9]{2}\.[0-9]{2}'
23:45.67
a...@ike:~$
I have used {,m} often enough in the past. I don't think it was broken
in Intrepid or Debian Etch.
