This script find_symbol.sh searches the MPI documentation for the name or names supplied to the script, and prints out the version of MPI where the symbol first appears. For example:

./finds_symbol.sh MPI_COMM_WORLD

outputs

symbol MPI_COMM_WORLD first occurs in MPI version 1.0

If the symbol is not found in any version, then a message will be printed stating so.

Multiple arguments can be supplied to the script, and each search result will be printed on a separate line. For example:

./find_symbol.sh MPI_COMM_WORLD MPI_PUT

outputs

symbol MPI_COMM_WORLD first occurs in MPI version 1.0
symbol MPI_PUT first occurs in MPI version 2.0
