I've been able to isolate a problem with csh on cygwin running on
Windows Server 2003 on a Xeon. The following script hangs after a
certain period of time ranging from a few minutes to a few hours.
set year = `date +%y`
set month = `date +%m`
set day = `date +%d`
set hour = `date +%H`
set minute = `date +%M`
set second = `date +%S`
set stamp = "$year$month$day $hour : $minute : $second"
The equivalent script in bash doesn't hang even after a day or more.
while [ 1 ]; do
echo $(date +%Y%m%d.%H%M%S)
This isn't the equivalent script. It's similar and the output is the
same, but you only call date once here, while in the other you call
it 6 times. Maybe that is way it seems to work for bash and not csh.
I have problems with bash/sh script hanging, but I haven't tried csh.
Has anyone else had problems with csh scripts on cygwin? Yes, I know
that some people don't recommend using csh (see "Csh programming
http://www.faqs.org/faqs/unix-faq/shell/csh-whynot/), but I'm stuck
with a whole lot of csh scripts and don't have time to port them all
at the moment.
Which I'm getting in 1.5.19-4 too, but I haven't tried the latest
snapshot. Which reminds me. Could you read http://cygwin.com/
problems.html and provide the information that it says to provide?
Also were in the script does it hang. It you type ps -ef what do you
see. What information does the /proc directory tell you. Can you
ctrl-c out of the script?
Basically, provide as much information as possible.
