The last 8 lines could be replaced with a shorter
Code:
ls -rt ${uehist}/pwroutages.master.${fullyear}* | while read x
do
cat $x >>${uehist}/pwroutages.master_all.${fullyear} && rm -f $x
done

Mainly what it does is:

It takes all the files matching ${uehist}/pwroutages.master.${fullyear}* absolute names from the older to the newer (-rt = -reverse time),

and concatenate the content of each and every file into the file ${uehist}/pwroutages.master_all.${fullyear}

After every successfull concatenation, it deletes the corresponding ${uehist}/pwroutages.master.${fullyear}* file
