Using linux-next cloned today (July 1), I then checkout out the revision 60d5c9f5b. The command git blame drivers/staging/brcm80211/brcmfmac/wl_iw.c -L3675,3675 then gives: 60d5c9f5 (Julia Lawall 2011-04-01 16:23:42 +0200 3675) if (!iscan->iscan_ex_params_p) { Then I try: git show 60d5c9f5 which gives: error: short SHA1 60d5c9f5 is ambiguous. error: short SHA1 60d5c9f5 is ambiguous. fatal: ambiguous argument '60d5c9f5': unknown revision or path not in the working tree. Use '--' to separate paths from revisions If I give git blame the -l option, every thing is fine. thanks, julia -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
