Jaguar automatically re-pre-binds apps if there is one running in their address space, which would result in different binaries. one experiment is to move egrep and fgrep and make new hard links and see if they exhibit the same behavior as the old ones.On Friday, December 20, 2002, at 05:21 AM, [EMAIL PROTECTED] wrote:I made the same assumption.On Thursday, December 19, 2002, at 11:35 , Ettore Aldrovandi wrote:On Thu, Dec 19, 2002 at 09:46:10PM -0500, [EMAIL PROTECTED] wrote:
No. Note the first column (the inode number) and the column between the permissions and the files' owner (the number of hard links to the file). Ettore Aldrovandi explained them in his mail.Unfortunately, /usr/bin/[ef]?grep is the same file three times, taking up three times as much space as should be necessary. ThisYes, this is indeed puzzling. /usr/bin/grep /usr/bin/[ef]grep are certainly different files. diff reports them as different, but I don't know how trustworthy diff is on binary files.Yikes! I saw that they were all the same size and *assumed* (my mistake) that they were all the same file. And while diff may or may not be reliable on binary files (in my old school way of thinking about Unix, it *isn't*), md5sum strongly indicates that the grep family aren't just copies of each other either:
'diff' recognizes the files as binary, and while I haven't verified this by checking the code, I take the implication that it is doing a byte-by-byte compare.
