Dynamic dialog in bash scripts

AndiOliver · 04-21-2004, 05:36 AM

This is a small part from a script I am trying to wrote:

Code:

dialog --clear --backtitle "<<<...   PROSOFT COMPUTERS   ...>>> Tel/fax: 40 246 231082" --title "MENIU PRINCIPAL" \
        --menu "Pentru a va deplasa in sus, respectiv in jos - sageti \n\
[Enter] pentru selectare\n\
Alegeti programul dorit:" 30 100 18 \
        "Arhivare"      "Backpup Server Prosoft Computers (Mail, Website, Homesite)" \
        "Alive"         "Verificare serverelor, clientilor online"\
        "Filtru"        "Diverse filtre pentru traficul pe server"\
        "Trafic"        "Estimari trafic reteaua Prosoft Computers"\
        "Programare"    "Programare sectiuni de rulare in mod automat"\
        "Altele"        "Alte comenzi utile in administrare"\
        "Iesire"         "Iesire din program" 2> menuchoice.temp.$$

It is working, but right now I got to the point where the item I would like to load them dynamicaly, from a file.
It seems so far that this dialog won't let me create it unless I put specific items like it is wroted in the example. so my question is:

How can I load dynamicaly items from a file to this dialog?

Thanks in advance for those who help me or tries to...

Hi,

I had the same problem a long time ago. My solution was to write a script which creates a script to do this.

The script you have sent is in some language I don't understand. So, I'm just guessing about the contents. My assumption is that you have a file (called dynamicinfo, say) with something like:

Arhivare Backpup Server Prosoft Computers (Mail, Website, Homesite)
Alive Verificare serverelor, clientilor online
Filtru Diverse filtre pentru traficul pe server

So, the script goes something like this: [newfile.sh is the new script that's being created]

Code:

#!/bin/ksh

touch newfile.sh
echo "#!/bin/ksh" >> newfile.sh

echo the first three lines of dialog command too. Use this:

Code:

cat >>newfile.sh <<EOF
dialog --clear --backtitle "<<<...   PROSOFT COMPUTERS   ...>>> Tel/fax: 40 246 231082"\
--title "MENIU PRINCIPAL" \
        --menu "Pentru a va deplasa in sus, respectiv in jos - sageti \n\
[Enter] pentru selectare\n\
EOF

Now, comes the interesting part. You need to read from the file (the file with the dynamic info, dynamicinfo), a whole line and then split it into two parts, one containing the first word and one containing the rest. So, something like this should do:

Code:

while read line
do
    echo "$line" | sed 's/\([^ ]*\) \(.*\)$/"\1" "\2"\\/' >>newfile.sh
done <dynamicinfo

echo '2> menuchoice.temp.$$' >>newfile.sh

Now, the newfile.sh script is ready. Call it with something like:

Code:

ksh newfile.sh
rm -f newfile.sh

I've skipped the parts of checking whether newfile.sh exists, and so on. Be careful!

I'd be glad to help out with anything you did not understand,
Arvind

in a file named "items" without quotes write the menu info as follows
"Arhivare" "Backpup Server Prosoft Computers (Mail, Website, Homesite)"
"Alive" "Verificare serverelor, clientilor online"
"Filtru" "Diverse filtre pentru traficul pe server"
"Trafic" "Estimari trafic reteaua Prosoft Computers"
"Programare" "Programare sectiuni de rulare in mod automat"
"Altele" "Alte comenzi utile in administrare"
"Iesire" "Iesire din program"

#!/bin/bash
3<>"items";
number=0;
declare -a Items;

while read -u 3
do
echo $REPLY
Items[$number]="$REPLY";
number=`expr $number + 1`;
done

COMMAND='dialog --menu HelloWorld 30 100 18 ';

i=0;
while [ $i -lt $number ]
do
COMMAND="$COMMAND ${Items[$i]}";
i=`expr $i + 1`;
done
COMMAND="$COMMAND 2>tmp.\$\$"
echo $COMMAND > .cmd.$$;
sh .cmd.$$;

Thank you all for help especially thanks to gizmo_thunder - it worked like charm.
It was just I've wanted to make with my script.
