Hello,
As stated in the title, I do some hacked parallel processing by running multiple instances of bash scripts, each in their own subshell. The code looks like this,

logsave
LOGSAVE(8) System Manager's Manual LOGSAVE(8)NAME
logsave - save the output of a command in a logfile
SYNOPSIS
logsave [ -asv ] logfile cmd_prog [ ... ]
DESCRIPTION
The logsave program will execute cmd_prog with the specified argument(s), and save a copy of its output to logfile. If the containing
directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out. A copy of the output will
also be written to standard output.
If cmd_prog is a single hyphen ('-'), then instead of executing a program, logsave will take its input from standard input and save it in
logfile
logsave is useful for saving the output of initial boot scripts until the /var partition is mounted, so the output can be written to
/var/log.
OPTIONS -a This option will cause the output to be appended to logfile, instead of replacing its current contents.
-s This option will cause logsave to skip writing to the log file text which is bracketed with a control-A (ASCII 001 or Start of
Header) and control-B (ASCII 002 or Start of Text). This allows progress bar information to be visible to the user on the console,
while not being written to the log file.
-v This option will make logsave to be more verbose in its output to the user.
