Follow-up Comment #2, bug #18633 (project grep): Yes, it does seem to be a locale problem. If I type grep '^[a-E]' filename then aAbBcCdDeE are included. When using LC_ALL=C grep '^[a-e]' grep then only abcde are included. My friend who has a different locale has no problems unless he types LC_ALL=en_GB.UTF-8 grep '^[a-e]' filename
My locale is: [EMAIL PROTECTED]:~/UnixProgramming$ locale LANG=en_GB.UTF-8 LC_CTYPE="en_GB.UTF-8" LC_NUMERIC="en_GB.UTF-8" LC_TIME="en_GB.UTF-8" LC_COLLATE="en_GB.UTF-8" LC_MONETARY="en_GB.UTF-8" LC_MESSAGES="en_GB.UTF-8" LC_PAPER="en_GB.UTF-8" LC_NAME="en_GB.UTF-8" LC_ADDRESS="en_GB.UTF-8" LC_TELEPHONE="en_GB.UTF-8" LC_MEASUREMENT="en_GB.UTF-8" LC_IDENTIFICATION="en_GB.UTF-8" LC_ALL= output of type -a grep: [EMAIL PROTECTED]:~/UnixProgramming$ type -a grep grep is /usr/local/bin/grep grep is /bin/grep I've also tested LC_ALL-en_US.UTF-8 and this suffers from the same problem. My friend has done a bit of investigation which might be of interest: "Link to the page of the manual that i'm kindof talking about. http://www.gnu.org/software/grep/doc/grep_8.html#IDX178 "It matches any single character that sorts between the two characters, inclusive, using the locale's collating sequence and character set" So, I think this is implying that the character set itself has no ordering, as it probably shouldn't, although you could infer one based upon the actually encoding underneath (however this is fairly nasty, as it's indirectly exposing the underlying storage structures, which shouldn't have to be sensibly ordered). Which if you've made it through that sentence - we're onto the locale's collating sequence. This would be the bit that says how to sort the letters. I'm guessing grep calls a function called get range, taking 2 arguments, start and end.. so, for a-c, it would call getRange(a,c), which would return abc, (or aAbBc) and then use that value in the [ any one from here brackets ]." _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?18633> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
