BASH help: translate a short csh script to bash
Hi,

I have a csh:

Code:
  set NODES = `cat $HOST_FILE`
  set NODELIST = $TMPDIR/namd2.nodelist
  echo group main >! $NODELIST
  foreach node ( $NODES )
    echo host $node >> $NODELIST
  end
  @ NUMPROCS = 2 * $#NODES

I am very frustrated to translate it to bash:

Code:
NODES = `cat $HOST_FILE`
NODELIST = $TMPDIR/namd2.nodelist
echo group main > NODELIST1
for  node in $NODES
do
    echo host $node >> $NODELIST
done
NUMPROCS = 2 * $#NODES

The script basically capture each line of file $NODELIST and add 'host' to the beginning of each line.
Can some please help to fix my translation?
Your time is greatly appreciated!
Todd
