I suspect the problem to be the following:
After changing the file /home/$usrName/.facet and writing the results to /home/testdir/$usrName (so far ok) you try to modify this file writing back to it immediately. This is FORBITTEN! Something like
sed 's/this/that' file > file.new
works, but
sed 's/this/that' file > file
won't. The reason is: sed will read the first line of the input file (which is "file"), apply any rules that might be applicable and then write the result (the changed or not changed line) to <stdout>. This <stdout> is at this moment pointing to "file" and this is why after the first line the file will contain nothing more than exactly that first line - so sed encounters the EOF and thinks it is finished. In the first example it is not writing back to its input file but some other file "file.new", which is why there is no problem.
There is another (perhaps minor) detail i found: You read from keyboard a variable "usrList" and do nothing with it. Why?
