shell Command execution Failing when executed from Java

Question

When I execute the below command on command line, it shows all the stored procedures and tables in the sybase DB.

printf \'sp_help\\ngo\\n\' | isql -Uxx -Pxxxx -         


        

Answer 1

Several things come to mind:

• Incomplete PATH environment variable (thus isql can't be found).
• If it's a command you provide, instead of messing with PATH you might want to make sure your are you in the correct working directory and call ./isql instead.
• Since you're using a pipe, you should let a shell execute this as in sh -c "foo | bar". Otherwise the | isql ... part is passed as argument to printf as well.
