Yes, but changing from mode 555 to 755 is not; that's livecode. . . .

Mine are generally stackname.yymmddv.livecode, where v starts at the first
one, and goes on.
But here's a fit of cleverness that seems to work, although it relies on
the OS or user to clean /tmp from time to time:
*on* saveStackRequest
*--keep a copy of the stack*
*local* stkNm, bkNm
*put* the short name of this stack into stkNm
*switch*
*--livecode's own stacks*
*case* char 1 to 3 of stkNm="Rev"
*case* stkNm="Message Box"
*pass* saveStackRequest
*break*
*case* stkNm begins with "dinfo_"
*case* stkNm begins with "dna_"
*case* stkNm begins with "out_"
*--never save these*
*break*
*default*
*--it must be a dh program stack*
*lock* messages
*save* this stack
*put* the seconds into bkNm
*convert* bkNm to dateItems
*put* char 3 to 4 of item 1 of bkNm \
& char -2 to -1 of ("0" & item 2 of bkNm) \
& char -2 to -1 of ("0" & item 3 of bkNm) \
& "." \
& char -2 to -1 of ("0" & item 4 of bkNm) \
& char -2 to -1 of ("0" & item 5 of bkNm) \
into bkNm
*set* the itemDel to "/"
*put* char 1 to -2 of item -1 of the long name of this stack & "." before
bkNm
*put* "cp " & char 8 to -2 of the long name of this stack & " /tmp/" before
bkNm
*unlock* messages
*get* shell(bkNm)
*break*
*end* *switch*
*end* saveStackRequest
So many more than time machine would do, and they go away in a couple of
days if not needed.
I also have a bmpVrsn routine to handle my major checkpoints through the
day (bump the v above)
