 script in makefile problem I wish to put a number of .db2 scripts in my makefile. However, some of the db2 scripts tries to revoke privileges from users that might do not have that privilege already, thus returns an error to the shell. I do not want the makefile to stop there, but simply ignore the errors. For example, I have the following in my makefile run: db2 -td@ script1.db2 db2 -td@ script2.db2 suppose one of the commands in script1.db2 fails (but does not create a problem at all, like trying to drop a table that does not exist), the makefile will not proceed to the second script file. How do i revise the commands so the makefile will run the second script even if some of the commands in the first script fails?      |

Standard prefixes for command lines in makefiles are @ and -. The @ means 'do not echo', and the '-' means ignore errors. Put a '-' in front of each command that might fail. It goes after the leading tab and before anything else (except, perhaps, the @). There are other more radical ways of ignoring errors in makefiles (-k option is OK in context, but this isn't one of those contexts; -i is usually not OK; and .IGNORE doesn't bear thinking about). -- Jonathan Leffler #include <disclaimer.h> Email: jleffler@earthlink.net, jleffler@us.ibm.com Guardian of DBD::Informix v2007.0226 -- http://dbi.perl.org/ |
