Shell script type switch examples

The following script uses the app, dbadmin, and stx111 parameters. The app parameter sets an environment variable. The script uses the dbadmin and stx111 parameters to call a utility that performs an action. The output of the job varies depending on the shell flag.

#!/bin/sh

DBNAME=$1

export DBNAME

dbrefresh -U $2 -P $3

exit $?

• If the -x flag was set when running the sample script, the job produces the following output:

  DBNAME=app

  + export DBNAME

  + dbrefresh -U dbadmin -P stx111

  DB refreshed

  + exit 0

• If the -v flag was set when running the sample script, the job produces the following output:

  #! /bin/sh -v

  CTM_RSVD=

  CTM_RSVD_START=

  CTM_RSVD_END=

  CTM0='/home2/ag620/refreshDB.sh'

  CTM00=$0

  DBNAME=$1 $CTM_RSVD

  export DBNAME $CTM_RSVD

  dbrefresh -U $2 -P $3 $CTM_RSVD

  DB refreshed

  exit $? $CTM_RSVD

• If the n flag was set when running the sample script, the job produces the following output:

  DB refreshed
