Difficulty to create .txt file from loop in bash
I've this data :

Code:
data1.txt

2020-01-27-06-00;/dev/hd1;100;/
2020-01-27-12-00;/dev/hd1;100;/
2020-01-27-18-00;/dev/hd1;100;/
2020-01-27-06-00;/dev/hd2;200;/usr
2020-01-27-12-00;/dev/hd2;200;/usr
2020-01-27-18-00;/dev/hd2;200;/usr

 data2.txt 

2020-02-27-06-00;/dev/hd1;120;/
2020-02-27-12-00;/dev/hd1;120;/
2020-02-27-18-00;/dev/hd1;120;/
2020-02-27-06-00;/dev/hd2;230;/usr
2020-02-27-12-00;/dev/hd2;230;/usr
2020-02-27-18-00;/dev/hd2;230;/usr

 data3.txt 

2020-03-27-06-00;/dev/hd1;130;/
2020-03-27-12-00;/dev/hd1;130;/
2020-03-27-18-00;/dev/hd1;130;/
2020-03-27-06-00;/dev/hd2;240;/usr
2020-03-27-12-00;/dev/hd2;240;/usr
 2020-03-27-18-00;/dev/hd2;240;/usr

I would like to create a .txt file for each filesystem ( so hd1.txt, hd2.txt, hd3.txt and hd4.txt ) and put in each .txt file the sum of the value from each FS from each dataX.txt. I've some difficulties to explain in english what I want, so here an example of the result wanted

Expected content for the output file `hd1.txt`:
Code:
2020-01;/dev/hd1;300;/
2020-02;/dev/hd1;360;/
2020-03;/dev/hd1;390:/

Expected content for the file `hd2.txt`:


Code:
2020-01;/dev/hd2;600;/usr
2020-02;/dev/hd2;690;/usr
2020-03;/dev/hd2;720;/usr

The implementation I've currently tried:

Code:
for i in $(cat *.txt | awk -F';' '{print $2}' | cut -d '/' -f3| uniq)
do
    cat *.txt | grep -w $i | awk -F';' -v date="$(cat *.txt | awk -F';' '{print $1}' | cut -d'-' -f-2 | uniq )" '{sum+=$3} END {print date";"$2";"sum}' >> $i

done

But it doesn't works...

Can you show me how to do that ?

mkdevalloc

mkdevalloc(1M)                                            System Administration Commands                                            mkdevalloc(1M)

NAME

       mkdevalloc - Make device_allocate entries

SYNOPSIS

       /usr/sbin/mkdevalloc

DESCRIPTION

       The mkdevalloc command writes to standard out a set of device_allocate(4) entries describing the system's frame buffer, audio and removable
       media devices.

       The mkdevalloc command is used by the init.d(4) scripts to create or update the /etc/security/device_allocate file.

       Entries are generated based on the device special files found in /dev. For the different categories  of  devices,  the  mkdevalloc  command
       checks for the following files under /dev:

       audio           /dev/audio, /dev/audioctl, /dev/sound/...
       tape            /dev/rst*, /dev/nrst*, /dev/rmt/...
       floppy          /dev/diskette, /dev/fd*, /dev/rdiskette, /dev/rfd*
       removable disk  /dev/sr*, /dev/nsr*, /dev/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s?
       frame buffer    /dev/fb

       All  entries  set  the  device-minimum  and device-maximum fields to the hex representations of ADMIN_LOW and ADMIN_HIGH, respectively. The
       device-authorization field is set to solaris.device.allocate, except for the framebuffer entry, where it is  set  to  *.  The  device-name,
       device-type and device-clean fields are set to the following values:

                       device-name      device-type   device-clean

       audio           audio            audio         audio_clean_wrapper
       tape            mag_tape_0,1,... st            st_clean
       floppy          floppy_0,1,...   fd            disk_clean
       removable disk  cdrom_0,1,...    sr            disk_clean
       frame buffer    framebuffer      fb            /bin/true
