perhaps our own limited assistance stems from your including only a snippet of the overall use. Looks like it is an eval of contents grepped out of an input file, which might be of use in explaining things...
In any case, note the following application of the %s modifier:
#!/bin/sh
$ORACLE_HOME/bin/sqlplus -S $orauserid/$orapasswd@$oradb << _TMP
alter session set nls_date_format = 'YYYYMMDD HH24:MI';
set linesize 100
set pagesize 400
ok the above is part of a script..i just wanna know what does sqlplus -S means?? as in why we need to insert the -S behind? (2 Replies)

Hello everyone,
I'm looking for the meaning of this expression, as I don't understand it quite clearly : $1^
What do you think it could be?
I thought either:
- match lines starting with argument 1 but it should be ^$1
- turn line around : word becomes drow
Thanks in advance for your... (4 Replies)

SDL_WasInit(3) SDL API Reference SDL_WasInit(3)NAME
SDL_WasInit- Check which subsystems are initialized
SYNOPSIS
#include "SDL.h"
Uint32 SDL_WasInit(Uint32 flags);
DESCRIPTION
SDL_WasInit allows you to see which SDL subsytems have been initialized. flags is a bitwise OR'd combination of the subsystems you wish to
check (see SDL_Init for a list of subsystem flags).
RETURN VALUE
SDL_WasInit returns a bitwised OR'd combination of the initialized subsystems.
EXAMPLES
/* Here are several ways you can use SDL_WasInit() */
/* Get init data on all the subsystems */
Uint32 subsystem_init;
subsystem_init=SDL_WasInit(SDL_INIT_EVERYTHING);
if(subsystem_init&SDL_INIT_VIDEO)
printf("Video is initialized.
");
else
printf("Video is not initialized.
");
/* Just check for one specfic subsystem */
if(SDL_WasInit(SDL_INIT_VIDEO)!=0)
printf("Video is initialized.
");
else
printf("Video is not initialized.
");
/* Check for two subsystems */
Uint32 subsystem_mask=SDL_INIT_VIDEO|SDL_INIT_AUDIO;
if(SDL_WasInit(subsystem_mask)==subsystem_mask)
printf("Video and Audio initialized.
");
else
printf("Video and Audio not initialized.
");
