On my Ubuntu linux computer I'm making a loop like this using my shell bash

HERE MY CODE "./upperscript"

cat filename.txt | while read LINE || [[ -n $LINE ]];

do

    ./script $LINE >> $LINE.txt 2>> $LINE.err & sleep 1

    wait;

done > /dev/null 2>&1 &

echo "[PID $!]"

Here I go

Now, when the script disappears there are a lot of forked process (one at a time) over -bash name like this

username    15029  0.0  0.3   7404  3060 ?        S    mag31   0:00 -bash

username    13849  0.8  0.6  33048  6432 ?        S    mag31   0:08  _ ./script HERE MY LINE

username    13869  0.1  0.3  33048  6451 ?        S    mag31   0:09    _ ./otherscript HERE MY LINE

username    13881  0.1  0.1  33048  6465 ?        S    mag31   0:08    _ ./otherscript HERE MY LINE

how to rename the process with pid 15029 that now it's called simply "-bash"?

I tryed also

$ chmod 777 /proc/15029/comm

chmod: changing permissions of '/proc/15029/comm': Operation not permitted

to do then

echo 'PROCESSNAME' > /proc/15029/comm"

but like u see the error is

"Operation not permitted" also using sudoers username or root (su)

if there's not a way, could I rename it from the process itself?

Saying using

bash -c "exec -a <MyProcessName> <Command>"

in a multiline command like my while?

Thanks a lot
