Displaying version information
On Windows, all AR System background processes support the -version command-line switch. With this switch, a command can write the application's version string to its standard output and exit.
Shared objects on UNIX hold the version information string in a global variable so that it can be displayed using a utility, such as strings with the grep command, as follows:
strings <fileName> | grep "ProdVers"
For example:
strings libar.a | grep "ProdVers"
If grep "ProdVers" is not used, strings display all the global strings, and it is difficult to determine the version string from the output.
Tip: For faster searching, add an asterisk to the end of your partial query. Example: cert*
