Dear all
I am installing some eda software using script. My OS is ubuntu 10.04 and the eda software writing in csh. Since ubuntu reading script file in sh writting. I need someone can help me to convert some definition in script from csh to sh. Below is part of script

set archinfo = `$installdir/bin/get_arch -r -c -t`
setenv ARCH $archinfo[1]
setenv CMIARCH $archinfo[2]
setenv mraarch ${ARCH}
setenv TMIARCH ${CMIARCH}
unsetenv OMP_NUM_THREADS
unsetenv KMP_BLOCKTIME
unsetenv LANG
unsetenv LC_ALL
limit coredumpsize 0

The sh cell command will post the error when it sees : setenv, unsetenv, limit and [ ]
How I can make a change of thoses? Thanks a lot

Why don't you run it with csh?

/usr/bin/csh <your script>

Or is it that you don't have csh? If so, you can try this...

archinfo=( $( $installdir/bin/get_arch -r -c -t ) )
export ARCH=${archinfo[1]}
export CMIARCH=${archinfo[2]}
export mraarch=${ARCH}
export TMIARCH=${CMIARCH}
export OMP_NUM_THREADS=""
export KMP_BLOCKTIME=""
export LANG=""
export LC_ALL=""
ulimit -c 0

Your script is tried and tested by the developers of the system you want to install and will work. It is possible for someone here to convert it to sh or bash for you and it work first time, but I would not want to chance it and it is better if you can run the original script. If tcsh does not exist on your system get it with the command:

sudo apt-get install tcsh

Then you will be able to run the code without having to rewrite it.
