Re: NCL and standard in

Actually, I use NCL for scripting any more. No 'escaping the shell' issues.

---
I  am not smart enough to use the bash shell.
Here is a C-shell example. The last line is pretty clear, isn't it.  :-)
#!/bin/csh -f
# test CLA [command line argument]
cat > test.ncl << "TEST"         # NCL code
   if (isvar("inputfile")) then
       print("inputfile="+inputfile)
   else
       print("Missing CLA")
   end if
"TEST"
 
 set a=foo.nc
 echo "===================="
 echo "echo: " $a
 echo "===================="
 echo "echo: " \'inputfile=$a\'
 echo "===================="
 eval ncl inputfile=\\\"$a\\\" test.ncl
 /bin/rm -f test.ncl
