comment SSH command with file redirect not working
I might also suggest sort -u -o /root/.ssh/authorized_keys /root/.ssh/authorized_keys, but check that the system's sort supports the -u flag (it's popular but not required by POSIX).

comment Zsh script how to concatanate array elements with string
If you want word-splitting, don't use double-quotes. The second for loop has a typo of sigin for sigind; is that it?

comment How to print a bash variable that has an array as value
Off-topic: you may prefer to read /proc/stat to get the same information more cheaply. See proc(5).

comment How to print a bash variable that has an array as value
I believe the rogue character is a newline (i.e. linefeed), even though it is displayed as VT. Therefore the correct filter is tr '\012' ' '.

comment Zsh script how to concatanate array elements with string
Interpolation means replacing $index with TopJets. Word splitting means replacing the single word $bkgarr with the 4 words TopJets BosonJets DiBoson TTbar instead of the single word "TopJets BosonJets DiBoson TTbar".

comment How to close all apps before X-server goes down?
If you don't like xsm (and who does?), you can use another; how about rox.sourceforge.net/desktop/ROX-Session ? And there's always Approach #1.

@MikhailMorfikov You're right, my answer wasn't too helpful if you didn't already use GDM. Is the updated answer any more useful?
