How to get boxed output with line wrapping?

Question

bash

There is a script that displays system info

VAR=$(echo -e "$MEM\n$HDD\n$CPU")
echo "$VAR2"

conclusion

Memory Usage: 277/1983MB (13.97%)
Disk Usage: 5/16GB (35%)
CPU Load: 0.00

I want to create a frame around the output, for this I use the function

banner() {
    msg="# $* #"
    edge=$(echo "$msg" | sed 's/./#/g')
    echo "$edge"
    echo "$msg"
    echo "$edge"
}

banner $VAR

Conclusion

#############################################################################
# Memory Usage: 277/1983MB (13.97%) Disk Usage: 5/16GB (35%) CPU Load: 0.00 #

Unable to output line by line

Answer 1

I want to create a frame around the output, for this I use the function
msg="# $* #"

something is not at all
like an option, the size can be controlled through column

MEM="Memory Usage: 277/1983MB (13.97%)"
HDD="Disk Usage: 5/16GB (35%)"
CPU="CPU Load: 0.00"
VAR="$MEM\n$HDD\n$CPU"
banner() {
  v="[email protected]"
  x=$(echo -e "$v" |awk '{if(length>max)max=length}END{for(i=1;i<max+5;i++){printf "#"}}')
  echo "$x"
  echo -e "$v" |awk '{print "# "$0" #"}' |column -t -s: -o: |column -t -s'#' -o'#'
  echo "$x"
}
banner "$VAR"

conclusion

#####################################
# Memory Usage: 277/1983MB (13.97%) #
# Disk Usage  : 5/16GB (35%)        #
# CPU Load    : 0.00                #

although if it is possible to initially control the type of receiving MEM, HDD, CPU, then it will be easier to write data through the same csv and format its output with appropriate programs, for example csview

MEM="Memory,277/1983MB,13.97%"
HDD="Disk,5/16GB,35%"
CPU="CPU,0.00,"
echo -e "$MEM\n$HDD\n$CPU" |csview -H --style Reinforced

conclusion:

┏────────┬────────────┬────────┓
│ Memory │ 277/1983MB │ 13.97% │
│ Disk   │ 5/16GB     │ 35%    │
│ CPU    │ 0.00       │        │

Answer 2

MEM="Memory Usage: 277/1983MB (13.97%)"
HDD="Disk Usage: 5/16GB (35%)"
CPU="CPU Load: 0.00"

banner() {
max=$(echo -e "$1"|awk '{if(length>max)max=length}END{printf max}')
echo -e "$1"|awk 'BEGIN{for(i=1;i<'$max'+4;i++){printf "#"};print "#"}{printf "# %'$max's #\n", $0}END{for(i=1;i<'$max'+4;i++){printf "#"};print "#"}'
}

banner "$MEM\n$HDD\n$CPU"

$ banner "$MEM\n$HDD\n$CPU"
