My satellite receiver is equipped with busybox, so a small linux version.
That is why I can not use certain commands like #tomorrow in date commands or #date -d "+1 day"
and thus I have to use: day1=$

Hi,
I have a fixed width file.
The way this file works is say for example there are 30 columns in it each with different sizes say 10,5,2, etc...
If data in a field is less than the field size the rest of it is loaded with spaces.
I would like an awk command to that would replace

taskset
TASKSET(1) User Commands TASKSET(1)NAME
taskset - retrieve or set a process's CPU affinity
SYNOPSIS
taskset [options] mask command [arg]...
taskset [options] -p [mask] pid
DESCRIPTION
taskset is used to set or retrieve the CPU affinity of a running process given its PID or to launch a new COMMAND with a given CPU affin-
ity. CPU affinity is a scheduler property that "bonds" a process to a given set of CPUs on the system. The Linux scheduler will honor the
given CPU affinity and the process will not run on any other CPUs. Note that the Linux scheduler also supports natural CPU affinity: the
scheduler attempts to keep processes on the same CPU as long as practical for performance reasons. Therefore, forcing a specific CPU
affinity is useful only in certain applications.
The CPU affinity is represented as a bitmask, with the lowest order bit corresponding to the first logical CPU and the highest order bit
corresponding to the last logical CPU. Not all CPUs may exist on a given system but a mask may specify more CPUs than are present. A
retrieved mask will reflect only the bits that correspond to CPUs physically on the system. If an invalid mask is given (i.e., one that
corresponds to no valid CPUs on the current system) an error is returned. The masks are typically given in hexadecimal. For example,
0x00000001
is processor #0
0x00000003
is processors #0 and #1
0xFFFFFFFF
is all processors (#0 through #31).
When taskset returns, it is guaranteed that the given program has been scheduled to a legal CPU.
OPTIONS -a, --all-tasks
Set or retrieve the CPU affinity of all the tasks (threads) for a given PID.
-p, --pid
Operate on an existing PID and do not launch a new task.
-c, --cpu-list
Specify a numerical list of processors instead of a bitmask. The numbers are separated by commas and may include ranges. For exam-
ple: 0,5,7,9-11.
-h, --help
Display usage information and exit.
-V, --version
Display version information and exit.
USAGE
The default behavior is to run a new command with a given affinity mask:
taskset mask command [arguments]
You can also retrieve the CPU affinity of an existing task:
taskset -p pid
Or set it:
taskset -p mask pid
PERMISSIONS
A user must possess CAP_SYS_NICE to change the CPU affinity of a process. Any user can retrieve the affinity mask.
