convert bash to tcsh

[alberto]

hi,
I would convert in tcsh this script
how I could fix it

regards

## Script for parallel LAMMPS17 job by Alberto
## Run script with 2 arguments:
## $1 = Name of input-file, without extension
## $2 = Numbers of nodes to use (ncpus=nodes*20)


if [ -z "$1" -o -z "$2" ]; then
echo "Usage: $0 <input_file> <np>"
fi

if [ $2 -ge 8 ]; then
NODES=$(($2/20))
CPUS=20
else
NODES=1
CPUS=$2
fi

cat<<EOF>$1.job
#!/bin/bash
#PBS -l nodes=$NODES:ppn=$CPUS:xeon20
#PBS -l walltime=9999:00:00
#PBS -N $1
#PBS -e $1.err
#PBS -o $1.sum
#PBS -j oe
job=$1 # Name of input file, no extension
project=\$PBS_O_WORKDIR
cd \$project
cat \$PBS_NODEFILE > \$PBS_O_WORKDIR/nodes.txt
# define the environment variable OMP_NUM_THREADS to indicate the number of threads that we want per program
export OMP_NUM_THREADS=$3
