$ ls -l sage-4.1.1/local/bin/python* -rwxr-xr-x 2 tornaria tornaria 5528068 2009-09-04 21:45 sage-4.1.1/local/bin/python -rwxr-xr-x 2 tornaria tornaria 5528068 2009-09-04 21:45 sage-4.1.1/local/bin/python2.6 -rwxr-xr-x 1 tornaria tornaria 1419 2009-09-04 23:54 sage-4.1.1/local/bin/python2.6-config lrwxrwxrwx 1 tornaria tornaria 16 2009-10-30 01:25 sage-4.1.1/local/bin/python-config -> python2.6-config The "2" in the second column indicates the number of hard link references; you can guess they are the same file b/c they have the same metadata --- you can confirm by looking at the inode numbers. What I actually did, is check out the tarball: $ tar tvf sage-4.1.1-core2-jsmath_fonts-x86_64-Linux.tar.gz | grep ^h hrwxr-xr-x tornaria/tornaria 0 2009-09-04 21:45 sage-4.1.1-core2-jsmath_fonts-x86_64-Linux/local/bin/python link to sage-4.1.1-core2-jsmath_fonts-x86_64-Linux/local/bin/python2.6 WRT symlinks: $ tar tvf sage-4.1.1-core2-jsmath_fonts-x86_64-Linux.tar.gz | grep ^l | wc -l 125 >> a. fix installation of python so that a symlink is used instead of a hard >> link > > Do you know where this bit of code is?

There's no posix way to copy hardlinks. The standard is just too restrictive, like a dinosaur: big, fat, and slow. We can try to adjust to posix, for the sake of portability, but that doesn't make it suitable. We can do it because we are small, lean, and fast :-) </rant> Gonzalo --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
