But script are working, maybe because user root from which that script are
starts uses /bin/csh shell?
this script starts with #!/bin/sh, which means it is supposed to run under
/bin/sh, where beace expansion does not need to be supported.
That doesn't necessarily mean the person writing (or later modifying) the
script was paying attention when they wrote the brace-expansion bits, and
it may have been tested on a system where /bin/sh was symlinked to
/bin/bash or another shell that does support brace expansion (the default
/bin/sh may have been overridden); also, the #! syntax won't override a
command like "/bin/bash myscript".
But your point is taken. If it's using brace expansion, then it should
probably start with #!/bin/bash rather than #!/bin/sh so that the correct
shell gets run absent /bin/sh symlinks and an explict-shell command line.
