Shell Script - File Input/Output in C
This is part of my code:

Code:
       
 for in_file in $1/*.in    # list of all .in files in working directory.    
 do                
     $c_file < $in_file > "$tempFile.out"             
      if  diff "$tempFile.out" $out_file  >/dev/null 2>&1 ;            
      then               
          echo "corresponding files are the same!"           
     else                 
          echo "different!"           
    fi 
done

$c_file is a C program, $in_file is an input file. "$tempFile.out" doesn't work.... I don't think the output file was created.



This code is inside a for loop, and for each loop, there is a different input file. A file is created after the first loop, but "$tempFile.out" isn't overridden for the next loops. So, for diff, it's comparing "$tempFile.out" with $out_file for each loop.
I want the output of $c_file < $in_file to override "$tempFile.out" for each loop.
Any ideas?

h5unjam

h5unjam(1)						      General Commands Manual							h5unjam(1)

NAME

       h5unjam - Extract the user block from a HDF5 file

SYNOPSIS

       h5unjam -i in_file.h5 [-u user_block | --delete] [-o out_file.h5]

DESCRIPTION

       h5unjam	splits	an  HDF5 file, writing the user block to a file or stdout and the HDF5 file to an HDF5 file with a header at byte 0 (i.e.,
       with no user block).

       If out_file.h5 is given, a new file is created with the in_file.h5 without the user block. In this case, infile.h5 is unchanged.

       If out_file.h5 is not specified, the user_block is removed and in_file.h5 is rewritten, starting at byte 0.

       If user_block is set, the user block will be written to user_block.  If user_block is not set, the user block (if any) will be  written	to
       stdout. If --delete is selected, the user block will not be not written.

EXAMPLE USAGE

       For an HDF5 file, with_ub.h5, with a user block, extract the user block to user_block.txt and the HDF5 file to wo_ub.h5.

	    h5unjam -i with_ub.h5 -u user_block.txt -i wo_ub.h5

RETURN VALUE

       h5unjam returns the size of the output file, or -1 if an error occurs.

CAVEATS

       This tool copies all the data (sequentially) in the file(s) to new offsets. For a large file, this copy will take a long time.

       The  most  efficient  way  to create a user block is to create the file with a user block (see H5Pset_user_block), and write the user block
       data into that space from a program.

       The user block is completely opaque to the HDF5 library and to the h5jam and h5unjam tools.  The user block is simply read or written as  a
       string  of  bytes,  which could be text or any kind of binary data.  It is up to the user to know what the contents of the user block means
       and how to process it.

       When the user block is extracted, all the data is written to the output, including any padding or unwritten data.

       This tool moves the HDF5 file through byte copies, i.e., it does not read or interpret the HDF5 objects.
