Full Discussion: Run awk command inside ssh
Top Forums UNIX for Advanced & Expert Users Run awk command inside ssh Post 303041661 by MadeInGermany on Sunday 1st of December 2019 05:38:05 AM
With my proposal the remote shell (e.g. bash) runs the input stream - no need to copy/delete any files.
You can even use parameters:
Code:
ssh remotehost /bin/bash -s arg1 arg2 < remotescript.sh

arg1 and arg2 are passed to $1 and $2, respectively.
 
Test Your Knowledge in Computers #268
Difficulty: Easy
In 1936, Turing published his paper 'On Computable Numbers, with an Application to the Entscheidungsproblem'. In this paper, Turing reformulated Kurt Godel's 1931 results on the limits of proof and computation, replacing Godel's universal arithmetic-based formal language with the formal and simple hypothetical devices that became known as Turing machines.

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. AUTHOR
