Something like this will work for bash
This will create two files, stdout and stderr containing the expected output, plus all output will also appear on screen. Replace ./myscript arg1 arg2 with the actual command you're using.
Hi all,
I need to redirect stdout and stderr to a file in a ksh shell. That's not a problem. But I need also the correct exit code for the executed command. In the example below I redirect correctly the stdout & stderr to a file, but I have the exit code of tee command and not for the mv... (2 Replies)
In bash, I need to send the STDOUT and STDERR from a command to one file, and then just STDERR to another file. Doing one or the other using redirects is easy, but trying to do both at once is a bit tricky. Anyone have any ideas? (9 Replies)
This is about getting all output to stderr and stdout localized. Nothing to do with redirecting output to a file (there already are some interesting threads about that issue on this forum).
What I intend to do is capturing all lines of text sent to the screen, compare them with an array of... (2 Replies)
Friends
I have to redirect STDERR messages both to screen and also capture the same in a file.
2 > &1 | tee file works but it also displays the non error messages to file, while i only need error messages.

Currently I am redirecting STDERR and STDOUT to a log file by doing the following
{
My KSH script contents
} 2>&1 | $DEBUGLOG
Problem is the STDERR & STDOUT do not have any date/time associated.
I want this to be something that i can embed into a script opposed to an argument I use... (4 Replies)
Dear all,
redirecting STDOUT & STDERR to file is quite simple, I'm currently using:
exec 1>>/tmp/tmp.log; exec 2>>/tmp/tmp.logBut during script execution I would like the output come back again to screen, how to do that?
Thanks

Hi folks
I need/want to redirect output (stdout, stderr) from an exec call to separate files. One for stderr only and two(!) different (!) ones for the combined output of stderr and stdout.
After some research and testing i got this so far :

afquerypointer
AFQUERY(3)AFQUERY(3)NAME
afQuery, afQueryLong, afQueryDouble, afQueryPointer - query the capabilities of the Audio File Library
SYNOPSIS
#include <audiofile.h>
AUpvlist afQuery (int querytype, int arg1, int arg2, int arg3, int arg4);
long afQueryLong (int querytype, int arg1, int arg2, int arg3, int arg4);
double afQueryDouble (int querytype, int arg1, int arg2, int arg3,
int arg4);
void *afQueryPointer (int querytype, int arg1, int arg2, int arg3,
int arg4);
PARAMETERS
querytype can be one of the following:
o AF_QUERYTYPE_FILEFMT
o AF_QUERYTYPE_INST
o AF_QUERYTYPE_INSTPARAM
o AF_QUERYTYPE_COMPRESSION
o AF_QUERYTYPE_COMPRESSIONPARAM
o AF_QUERYTYPE_MISC
o AF_QUERYTYPE_MARK
o AF_QUERYTYPE_LOOP
arg1, arg2, arg3, and arg4 are integer selectors whose meaning depends upon querytype.
RETURN VALUE
Upon success, afQuery will return a non-null AUpvlist value. Upon failure, afQuery will return null while afQueryLong and afQueryDouble
will return -1 and afQueryPointer will return null.
Pointers representing character strings are owned by the Audio File Library and must not be freed; all other pointer values must be freed
by the caller.
DESCRIPTION
For AF_QUERYTYPE_FILEFMT, the following selectors are valid values for arg1:
AF_QUERY_LABEL
Request a short label string for the format (e.g., "aiff").
AF_QUERY_NAME
Request a short name for the format (e.g., "MS RIFF WAVE").
AF_QUERY_DESC
Request a descriptive name for the format (e.g., "Audio Interchange File Format").
AF_QUERY_IMPLEMENTED
Request a boolean value indicating whether the format is implemented for reading and writing in the Audio File Library.
AF_QUERY_ID_COUNT
Request the total number of formats implemented.
AF_QUERY_IDS
Request an integer array of the id token values of all implemented file formats.
AF_QUERY_COMPRESSION_TYPES
Used with the selector AF_QUERY_VALUE_COUNT in arg2, this will return a long integer containing the number of compression schemes
available for use within the format specified in arg3. Used with selector AF_QUERY_VALUES, it returns a pointer to an integer array
containing the compression id values of the compression schemes supported by the format specified in arg3.
AF_QUERY_SAMPLE_FORMATS
Used with the selector AF_QUERY_DEFAULT in arg2, this will return the default sample format for the file format specified in arg3.
AF_QUERY_SAMPLE_SIZES
Used with selector AF_QUERY_DEFAULT in arg2, this will return the default sample width for the file format specified in arg3.
For AF_QUERYTYPE_INST, the following selectors are valid for arg1:
AF_QUERY_SUPPORTED
Request a boolean value indicating whether the file format in arg2 supports instruments.
AF_QUERY_MAX_NUMBER
Request an integer value indicating the maximum number of instruments supported by the file format in arg2.
For AF_QUERYTYPE_INSTPARAM, the following selectors are valid for arg1:
AF_QUERY_SUPPORTED
Request a boolean value indicating whether the file format in arg2 supports instrument parameters.
AF_QUERY_ID_COUNT
Request an integer value indicating the number of instrument parameters supported by the file format in arg2.
AF_QUERY_IDS
Request an integer array containing the instrument parameter values for the file format in arg2.
AF_QUERY_TYPE
For the file format in arg2, request the type of the instrument parameter in arg3.
AF_QUERY_NAME
For the file format in arg2, request the name of the instrument parameter in arg3.
AF_QUERY_DEFAULT
For the file format in arg2, request the default value of the instrument parameter in arg3.
ERRORS
afQuery can produce the following errors:
AF_BAD_QUERYTYPE
The query type is unsupported.
AF_BAD_QUERY
The arguments to the query are bad.
