Ok, now that I am getting used to some things in bash, I think I'd like to make a script to download my modified Slax from the Lug

. The part that I need a little instruction on is how to script in the prompting from the lug on a u/n, and p/w. This script would be helpful as it would just d/l whatever the most current that I have done (speaking of, i think that i am do to make some changes). then in the same script I would have the automatic d/l of the newest user config for it as well. Right now I have a good idea in my head on what I need to do, except for the u/n & p/w bit. Any help wold be greatly appreciated.

ok here we go so far...

Code:

#!/bin/bash

cd ~/
mkdir Modified_Slax
cd Modified_Slax

wget http://members:usalug@www.usalug.org/ISOS/coastie-slax/usalugslax.iso

wget http://members:usalug@www.usalug.org/ISOS/coastie-slax/usalug.mo

wget http://members:usalug@www.usalug.org/ISOS/coastie-slax/md5sum.txt

how can i compare the md5 of the iso to the md5sum.txt automatically in the script

from there I want to mount the iso and copy all contents to the folder that i created. and then attempt to insert the config module into the a dir. then the user would just have to go to the dir where the make_iso.sh script is that comes with slax.

wget http://members:usalug@www.usalug.org/ISOS/coastie-slax/md5sum.txt

md5sum usalugslax.iso>usalug.txt

i am now working on a if statement to check the md5sums, then if they equal, to keep going, if they are different to exit.

then echo "The md5sums match"; else echo "The md5sums don't match...exiting" && exit 1
fi

ok now if i want to mount the iso then the user would have to be run as root right

cuz i would like to mount the iso and then copy all contents of the iso to the /home/user dir. ....though maybe more realistic to copy it to a new dir. in /home. what you all think

md5sum usalugslax.iso>usalug.txt

should be

md5sum usalugslax.iso > usalug.txt

that's just from reading it really quick..... not sure if that helps or not, i haven't ran it myself yet.....

well i did some tinkering....and it works...not quite like i envisioned yet...maybe you guys could give me a little help :idea:

mkdir root
mv usalug.mo root
cd /home/USALUG

#time to clean up
clear
umount Mount

rm md5sum.txt

rm usalug.txt

exit

it doesn't make the /root folder inside of /home/USALUG/New/Mount/rootcopy....so it doesn't put the usalug.mo in the right dir. other than that...it works

i fixed one of the problems, it should now create the dir, and move the usalug.mo to the correct folder

Nice script coastie! Here's a couple suggestions to get your md5 checksums working:

coastie wrote:

Code:

wget http://members:usalug@www.usalug.org/ISOS/coastie-slax/usalugslax.iso

clear
#md5sum usalugslax.iso > usalug.txt
#read usalug.txt md5

wget http://members:usalug@www.usalug.org/ISOS/coastie-slax/usalug.mo

#clear

wget http://members:usalug@www.usalug.org/ISOS/coastie-slax/md5sum.txt

clear

#read md5sum.txt answer

if [[ `md5sum -c md5sum.txt` == 0 ]]
then echo "The md5sums match"; else echo "The md5sums don't
match...exiting" && exit 1
fi

If you have the md5sum.txt file that was generated by md5sum for a set of files, you simply need to run the md5sum utility with the -c option and it'll look at the md5sum.txt file and check the file names in it against the files in the current directory and then calculate the md5 for each matching file and compare it against the value in the md5sum.txt file. *whew*

Said another way if your md5sum.txt file looks like:

Code:

abcdef0123456789 foo.txt
0123456789abcdef bar.txt

when you run

Code:

md5sum -c md5sum.txt

it'll check the current directory for foo.txt and bar.txt. It will then calculate the md5 hash for each file and compare those hashes against the hashes in the md5sum.txt file associated with the corresponding file name. If a file is missing or changed, the md5sum check will fail with an exit status of 1.

That way you don't have to calculate the md5 sum of each file yourself and then parse through the md5sum.txt file to find the right hash value to compare your cacluated value against.

ok figured i'd post where i would like to see this script go. from here i'd like to put in an option for allowing the user to insert files/dir. into the /root dir. eventually this will turn into something for the live disk for usalug
