Assuming that you're using a shell that performs basic POSIX-required parameter expansions, Scrutinizer already gave you two ways to do what you want in post #6 in this thread.
If you aren't using a POSIX-conforming shell, you need to answer the questions I raised in post #7 in this thread so we can help you find something that will work in your environment.

I know this should be simple, but I've been manning sed awk grep and find and am stupidly stumped :(
I'm trying to use sed (or awk, find, etc) to find 4 characters on the second line of a file.txt 44-47 characters in. I can find lots of sed things for lines, but not characters. (4 Replies)

pthread_detach
pthread_detach(3) Library Functions Manual pthread_detach(3)
NAME
pthread_detach - Marks a thread object for deletion.
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
SYNOPSIS
#include <pthread.h>
int pthread_detach(
pthread_t thread);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
IEEE Std 1003.1c-1995, POSIX System Application Program Interface
PARAMETERS
Thread object being marked for deletion.
DESCRIPTION
This routine marks the specified thread object to indicate that storage for the corresponding thread can be reclaimed when the thread ter-
minates. This includes storage for the thread argument's return value, as well as the thread object. If thread has not terminated when
this routine is called, this routine does not cause it to terminate.
When a thread object is no longer referenced, call this routine.
The results of this routine are unpredictable if the value of thread refers to a thread object that does not exist.
A thread can be created already detached by setting its thread object's detachstate attribute.
The pthread_join(3) routine also detaches the target thread after pthread_join(3) returns successfully.
RETURN VALUES
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows:
Successful completion. The value specified by thread does not refer to a joinable thread. The value specified by thread cannot be found.
ERRORS
None
