Thank you very much reborg.
I am going to follow whatever approach you suggested. I have a small concern here. In future, if some one comes and adds one more printf to the program (for debugging purpose), the script won't function properly right??

Is it possible to write the output values to a common memory which can be used by Unix shell as well as C program. Once the C program writes the output to that common memory , can Unix pick the values?
Since the program deals with passwords I can't write the output to a temp text file so that shell script reads the file and delete it.

How about writing the values to environment variables from C and accessing from Unix?

Iam new to Unix and C, please correct me if my questions are dumb.

Thanks
Rao.

NAME
mkmanifest - create a shell script to restore Unix filenames SYNOPSIS
mkmanifest [ files ] DESCRIPTION
Mkmanifest creates a shell script that will aid in the restoration of Unix filenames that got clobbered by the MSDOS filename restrictions. MSDOS filenames are restricted to 8 character names, 3 character extensions, upper case only, no device names, and no illegal characters. The mkmanifest program is compatible with the methods used in pcomm, arc, and mtools to change perfectly good Unix filenames to fit the MSDOS restrictions. EXAMPLE
I want to copy the following Unix files to a MSDOS diskette (using the mcopy command). very_long_name 2.many.dots illegal: good.c prn.dev Capital Mcopy will convert the names to: very_lon 2xmany.dot illegalx good.c xprn.dev capital The command: mkmanifest very_long_name 2.many.dots illegal: good.c prn.dev Capital > manifest would produce the following: mv very_lon very_long_name mv 2xmany.dot 2.many.dots mv illegalx illegal: mv xprn.dev prn.dev mv capital Capital Notice that "good.c" did not require any conversion, so it did not appear in the output. Suppose I've copied these files from the diskette to another Unix system, and I now want the files back to their original names. If the file "manifest" (the output captured above) was sent along with those files, it could be used to convert the filenames. SEE ALSO
