------ Solution ------- -------------------------------------
uname-r
cat / proc / version
cat / etc / SuSE-release
cat / etc / issue
cat / etc / issue.net
------ For reference only -------------------------- -------------
linux world and the windows inside the patch name is not the same as it
------ For reference only ---------- -----------------------------
uname-a to see the version information
------ For reference only ---------------------------------------
/ etc / issue can be seen to sp , no word is sp0 , but this information may be modified
/ proc / version can be, but is not easy to read
uanme-r most shy
Naturally, I am telling you now

suse 11: 2.6.27.19-5-pae
suse 11 sp1: 2.6.32.12-0.7-pae
suse 11 sp2: 3.0.13-0.27-pae
