The script:
#/bin/bash
_Box () {
str="$@"
len=$((${#str}+4))
for i in $(seq $len); do echo -n '*'; done;
echo; echo "* "$str" *";
for i in $(seq $len); do echo -n '*'; done;
echo
}
_Box "Welcome to AUDIT menu"
Execute the script:
$ ./box.sh
*************************
* Welcome to AUDIT menu *
*************************
Some points on the above script:
a) In the script, _Box is a function for generating style box. Any text sent as its argument will be shown within a stylish text box (as we saw above)
b) $@ : List of all shell arguments (here arguments to the function _Box)
c) len variable will be assigned to length of the string(argument)+4. Read how we can find string length in bash here
d) The for loops will print "len" number of * (read about seq)
e) -n option with echo (-n: do not output the trailing newline)

Thanks for sharing.
or just
_Box () {
echo $@ | sed -e 's/^/../' -e 's/$/../' -e 's/./*/g'
echo $@ | sed -e 's/^/* /' -e 's/$/ */'
echo $@ | sed -e 's/^/../' -e 's/$/../' -e 's/./*/g'
}
@Amir, thanks for your compliment.
@christias, its a great idea, thanks.
printf '%s\n' "Hello, world!" |\
sed -e 's/.*/* & */;h;s/./*/pg;x;G'
printf '%s\n' "Hello, world!" |\
perl -lne '
$a = "*" x length($_ = "* $_ *");
print for $a, $_, $a;
