title: Export: '0.0' : not a valid identifier in Bash
body: <p>I am fairly new to Bash scripting and am trying to set environment and libraries to use and then build a particular script. Here is the Bash script I wrote:</p>
  
  <pre><code>#! /bin/bash
  
  export DISPLAY :0.0
  #setenv LD_LIBRARY_PATH /usr/local/szip2.1/lib:${LD_LIBRARY_PATH}
  # above line should be equivalent to
  export LD_LIBRARY_PATH "/usr/lib64:/usr/lib:$LD_LIBRARY_PATH"
  
  module load Szip/2.1-gmpolf-2015
  module load cuda/6.5
  
  #while ( 1 )
    cd /home/sbansal6/misr-stereo-2013.11.24
    /home/sbansal6/misr-stereo-2013.11.24/bin/misr-stereo /home/sbansal6/ellipsoids/0034007 AN AA
  #end
  </code></pre>
  
  <p>And here is what I get as the error:</p>
  
  <pre><code>[sbansal6@cg-gpu01 STEREO]$ ./mstdrv.csh
  ./mstdrv.csh: line 3: export: `:0.0': not a valid identifier
  ./mstdrv.sh: line 6: export: `/usr/lib64:/usr/lib:/sw/cuda/6.5/lib64:/sw/EasyBuild/software/Szip/2.1-gmpolf-2015/lib:/sw/EasyBuild/software/ScaLAPACK/2.0.2-gmpich-2015-OpenBLAS-0.2.14-LAPACK-3.5.0/lib:/sw/EasyBuild/software/FFTW/3.3.4-gmpich-2015/lib:/sw/EasyBuild/software/OpenBLAS/0.2.14-GCC-4.9.2-binutils-2.25-LAPACK-3.5.0/lib:/sw/EasyBuild/software/MPICH/3.1.4-GCC-4.9.2-binutils-2.25/lib:/sw/EasyBuild/software/GCC/4.9.2-binutils-2.25/lib/gcc/x86_64-unknown-linux-gnu/4.9.2:/sw/EasyBuild/software/GCC/4.9.2-binutils-2.25/lib64:/sw/EasyBuild/software/GCC/4.9.2-binutils-2.25/lib:/sw/binutils-2.25/lib': not a valid identifier

  </code></pre>
  
  <p>I am basically trying to add the libraries from Szip and Cuda in my environment and then build a C++ program which is at the path I wrote later. I do understand that the last error that I got which said error while loading shared libraries: libglut.so.3 is because I don't have that library in my libraries. </p>
  
  <p>I am sorry if this question is trivial. I appreciate any help. Thanks in advance. </p>
  
  <p>UPDATE:
  I have also tried using setenv from csh but it is still not working.</p>
