Nice to see you on the list again!
I think in most cases, the script is mapped into memory, rather than
read by the interpreter a few bytes each time a statement executes, so
most likely changing the script has zero effect. But sometimes it can
cause the job to fail, it all depends on how it is submitted and how
the "shebangs" interpreter handles the script.
yeah, it happened to me once that I noticed a cosmetic failure in a
running script (outside of SGE) and while the script was still running
I tried to edit the script before I forget this issue. At some time
later the running script crashed, but I don't recall the error
message. I was also in the opinion, that a script with a few kB will
be read at once into memory and it's safe to edit the script. But in
the end Im learned that it's not the case and the source of a running
script shouldn't be touched.
NB: Having classic spooling it should be possible to edit the copy of
the script SGE saved, but it won't change the already read resource
request(s), just the statements. But I would prefer to resubmit the
(corrected) job and maybe change the priority by hand.

If I want to edit batch file of running job in sge now, is there
any method
to do it?
You can change the job script but it is not going to affect the job
that was submitted to SGE, as SGE has its own copy in the spool
directory.

... Unless it was submitted with "-b y", where it doesn't make a
copy.
Once the job has actually started running, in most cases it can't
be changed.
If it's a compiled scripting language like perl, for example it's
parsed at load time.
