Hi,
Is there any chance the script -q could be changed to not add " Script
started on %s"? It would be a lot quieter and it would take only a simple
If (!qflg)
fprintf(fscript, _("Script started on %s"), obuf);
I would gladly make the change, but there may be political reasons not to
change it.
--The rest of this email is not necessarily a bug. It is at least a
limitation that should be documented.
I found a race condition occurs in script between the grandchild process
actually executing the command (causing the signal to fire when done) and
the assignment of the child pid as a result of the fork() call.
Given a short lived program (I was testing with hostname), I called
script -c hostname
This can lock up if the signal handler executes before the fork() call
assigns the value of the (grand)child pid to the variable child.
If you call script in a loop, it is bound to occur within a couple of
iterations.
Thanks,
Vladimir Giszpenc
FYI I am looking at:
/usr/src/redhat/SOURCES/util-linux-2.13-pre6/misc-utils/script.c
