One approach is to use kill -0 to track the existence of the background process in the process table.

eg.
Code:
$ cat tmp.sh
#!/bin/bash

./tmp1.sh& 
tmp_1_pid=$!
exited=0
while [ $exited -eq 0 ];do
    sleep 1
    kill -0 $tmp_1_pid  
    exited=$?
done

echo container finished


$ cat tmp1.sh
#!/bin/bash

sleep 5
echo tmp 1 finished

$ . tmp.sh
tmp 1 finished
[2]-  Done                    ./tmp1.sh
-bash: kill: (6308) - No such process
container finished

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_MatrixTranspose_U8(mlib_u8 *xz, mlib_s32 mn);

       mlib_status mlib_MatrixTranspose_S8(mlib_s8 *xz, mlib_s32 mn);

       mlib_status mlib_MatrixTranspose_S8C(mlib_s8 *xz, mlib_s32 mn);

       mlib_status mlib_MatrixTranspose_S16(mlib_s16 *xz, mlib_s32 mn);

       mlib_status mlib_MatrixTranspose_S16C(mlib_s16 *xz, mlib_s32 mn);

       mlib_status mlib_MatrixTranspose_S32(mlib_s32 *xz, mlib_s32 mn);

       mlib_status mlib_MatrixTranspose_S32C(mlib_s32 *xz, mlib_s32 mn);

DESCRIPTION

       Each of these functions performs an in-place transpose of a square matrix.

       For real data, the following pseudo code applies:

       for (i = 1; i < mn; i++) {
	   for (j = 0; j < i; i++) {
	       tmp	    = xz[i*mn + j];
	       xz[i*mn + j] = xz[j*mn + i];
	       xz[j*mn + i] = tmp;
	   }
       }

       For complex data, the following pseudo code applies:

       for (i = 1; i < mn; i++) {
	   for (j = 0; j < i; i++) {
	       tmp0		    = xz[2*(i*mn + j)];
	       tmp1		    = xz[2*(i*mn + j) + 1];
	       xz[2*(i*mn + j)]     = xz[2*(j*mn + i)];
	       xz[2*(i*mn + j) + 1] = xz[2*(j*mn + i) + 1];
	       xz[2*(j*mn + i)]     = tmp0;
	       xz[2*(j*mn + i) + 1] = tmp1;
	   }
       }

PARAMETERS

       Each of the functions takes the following arguments:

       xz	       Pointer to the source and destination matrix.

       mn	       Number of rows and columns in the matrix.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
