Scripting Help Required - DPKG

Hello!!

I need a little help with scripting.

I want to install a .DEB from a script (4 in totoal).

I had the idea, but did not go right..

Essentially I want this:

(located in MyDocs)

Code:

#!/bin/sh



cd /specified-folder/





sudo dpkg -i genericprogram-name_test.deb



sudo dpkg -i genericprogram-name1_modules.deb



sudo dpkg -i generic_program-name2_special.deb



sudo dpkg -i generic_program-name3.deb

This spits out a bunch of errors saying --help and such. Nothing of help.

I use dpgk -i to install these *.deb files normally. Please help. :o

NP breh, What is more important is you understand the script so that in the future you will be better at writing 'em.

Code:

#!/bin/sh

cd /specified-folder/

You clearly know what that stuff is.

Code:

echo "dpkg -i *.deb" | root

Here we use the pipe '|' it is a special unix character that essentialy allows us to direct the output of a program to another program. In this example, the 'echo' command simply echos whatever parameter you give it. In this case 'dpkg -i *.deb'. This string is enclosed in quotes so the echo program knows it is a single string.

So echo echos that string back to us, we then use pipe to direct that string to the program root. (root is of course 'root shell', the land of sudo.)

So in essence we have:

SAY 'dpkg -i *.deb' TO root

Code:

echo "job done!"

echos 'job done' to the current shell, as we are working on the current shell we see job done!

comprende?

Re: Scripting Help Required - DPKG

Unfortunately this keep throwing errors.

Using the same as you posted:
dpkg: error processing *.deb (--install): cannot access archive: No such file or directory. Errors encounered while processing: *.deb (I have also added the start of the filename).

When I do it using the full filename:
Error is:

./script
line 6: syntax error: "|" unextected

Edit: If I remove the pipe | all it does is echo the words :(

I am doing all this on the N900 if thats any different.

Re: Scripting Help Required - DPKG

oopz

As the *.deb is in the quotes it is being treated as a literal string as opposed to a globbed expression.

Replace the line with:

Code:

sudo dpkg -i *.deb

So much for trying to show off huh?

Re: Scripting Help Required - DPKG

Code:

#!/bin/sh

sudo apt-get install kernel-power

cd wl1251-maemo/binary/kernel-power/

sudo dpkg -i *.deb

Will install ALL .deb in that directory.

Re: Scripting Help Required - DPKG

You're excellent!
I used the one you said that will install all. It worked perfectly!
But what would I do to install.. Maybe 2 only.

Just seems odd that it failed to install one using the same method.

Also: VI_ what does your signature mean/do....

Re: Scripting Help Required - DPKG

what does this mean?

Code:

#!/bin/sh

i'm planning to learn all this when i finish my exams ^^

Re: Scripting Help Required - DPKG

Shell script.
You can also use #!/bin/bash

I'm not sure what it fully means in the Linux terminology, the way I know it " this is a script";
