There is a very big overlap in what good developer and sysadmin should know about Linux. There are a lot of tasks, which in one teams performed by developer and in other — by sysadmin. Random topics which IMHO more specific for sysadmin work: 1. Troubleshooting and performance analysis. There is excellent site about performance: http://www.brendangregg.com/linuxperf.html http://www.brendangregg.com/linuxperf.html I don't know a good resource on troubleshooting, but some tools are the same. 2. Problem can be anywhere including network so the next topic is networks. There is excellent book TCP/IP Illustrated — old, but still relevant. 3. Sysadmin often spends a lot of time in a shell so it is good to know it very well (and common shell commands too).
