newbie scripting: Writeing a Shell script Qu

hoodedmanwithsythe · 03-05-2007, 05:23 PM

ok i am a newbie(in my opinion but according to some i am not)
and i am writing a shell script for comparing 2 dirs for that will print the differences between the 2 dirs to the shell.
I think i have the rough idea on how to do this but i am still not sure.
what i need is the shell equivalent to the following python code:

Code:

#!/usr/bin/env python
dirone = raw_input("what is the first dir name?")
print "Setting..." dirone
dirtwo = raw_input("what is the second dir name?")
print "Setting..." dirtwo

outputdir = raw_input("what is the output dir?")
where dirone and dirtwo are environment variables for use in a late part of script. I have trawled the web and this forum and found nothing on this so after a long time looking i have decided to post a thread on it.
here is the shell script so far:

Code:

#!/bin/sh
<insert code here>
cd $dirone
find > $outputdir/dirone.txt
cd $dirtwo
find > $outputdir/dirtwo.txt

thanks in advance

Thanks that helped a lot as is follows a very similar layout as the one i learned python fromand so i found it easy to follow here is the script if any one wishes to use it.
I will be making a more useful program in a while that will also handle the backup and restore aspect of things as well as this folder comparator.
if i was to redo this from scratch i would consider writing it in assembly but this would be far more difficult even if it meant that it was compatible with more systems (rather than just ones with /bin/sh).
again thanks for the help and i will possibly be asking more questions in this topic for the other part of this project.

Code:

#!/bin/sh
# This script was written for the purpose of compairing 2 folders so as you can check to see what files 
# are present in the first compaired to those in the second.
# Showing this by the use of the </> arrows. < meaning in the first folder but not the second folder
# and > meaning in the second folder but not the first folder.
# outputting to a text file named Output.txt

#start of file
#setting intial variables
outputfile=Output.txt
dironefile=dirone.txt
dirtwofile=dirtwo.txt
#requesting optional variables
echo "What is the Output Directory(full Dir Name Not the Local)? " #setting an optional variable as it is inputed by the user (echo "<place text here>" ; read <env variable> is used as an equivilent to <env variable>=raw_input("<place text here>") as in python)
read outputdir
echo "Setting the Output Directory to $outputdir. " #echo is the shell equivilent to print "" in python
echo Set to $outputdir Dir 
echo "What is the First Directory For Compairing(Full Dir Name Not the Local)? "
read dirone
echo "Setting the First Directory for Compairing to to $dirone. "
echo Set to $dirone .
echo "What is the Second Directory For Compairing(full Dir Name Not the Local)? "
read dirtwo
echo "Setting the Second Directory for Compairing to to $dirone. "
echo Set to $dirtwo .
cd $dirone #moving to a directory
find > $outputdir/$dironefile #brutaly useing the 'find' command to get a files list with '>' redirecting the output to a file (as set by environ ment variable at start)
cd $dirtwo
find > $outputdir/$dirtwofile
cd $outputdir
diff $dironefile $dirtwofile > $outputdir/$outputfile #useing diff in correct mannor to find all the diferences betwean the two directories
cat $outputdir/$outputfile #showing the output of the program on the screen

ok a quick update and a question. first the question how do I get a current dir pure location from shell with out hardwiring in to the program. and can some one please move this thread to the Non-*NIX Forums>Programming as i think it will serve more purpose there.
and the update to the program so far

Code:

#!/bin/sh
# This script was written for the purpose of compairing 2 folders so as you can check to see what files 
# are present in the first compaired to those in the second.
# Showing this by the use of the </> arrows. < meaning in the first folder but not the second folder
# and > meaning in the second folder but not the first folder.
# outputting to a text file named Output.txt

#start of file

outputfile=Output.txt
dironefile=dirone.txt
dirtwofile=dirtwo.txt
#requesting optional variables
#setting an optional variable as it is inputed by the user (echo "<place text here>" ; read <env variable> is used as an equivilent to <env variable>=raw_input("<place text here>") as in python)
#echo is the shell equivilent to print "" in python

You mean the pwd command?

Tinkster · 03-09-2007, 12:43 PM

Moved per OPs request.

P.S.: Next time you want your thread moved report it :}
I don't think that all posts are being read by mods.

yes thank you that helps immediately now i can finish this section of the script.

I will do thanks.

By-the-way I will be expanding this project in to a full backup utility and if I have time between my upcoming exams i will possible convert to python because I can write with python and have experience in TK (Tkinter libraries) based scripts and so generate a full python based GUI. But only if i have time.
The reason i started this project was cause someone i know wants a backup util similar to syncback that will run on Linux and he doesn't like using any of the current ones.

Tinkster · 03-09-2007, 02:12 PM

Do you know which current ones he has evaluated? :} "Any"
sounds a bit much, given the multitude out there.

Cheers,
Tink

Yeah, really. The problem you originally posted (comparing two directories and sending the differences to the shell) can be done with the diff command. The overall script looks like it could be easily accomplished with rsync.

hoodedmanwithsythe · 03-09-2007, 05:19 PM

true but as i say i am a newbie and so i don't know a what this rsync command is and if you look i do use the diff command, not in the way you are thinking i am sure but i am just comparing my intermediate python/tk knowledge and dragging this into a basic backup program for a friend.
and I admit I only write programs as I need them and I don't actually even consider it a hobby of mine as I only do it about once or twice a year.
and so my knowledge and understanding stays pretty low.
I actually work as a digital 3d artist(when not at collage) and don't even touch the programming side of things in a work environment cause i don't need to. I don't wish to sound ungrateful but it's not my area and i can't keep tabs on more than a few ways of doing things especialy considering i don't do this often and as the time i am not in collage i am working as a digital 3d artist i don't have time to take this up as a hobby.
so unless this rsync command and way of useing diff is going to speed up the way that things are currently progressing then i would rather that you didn't try to explain it to me as i will end up just ballsing it up as i am not the programmer type and i can't work the way you guys do and i just wont understand and you will end up just getting pissed off with trying to explain something to me that might as well be quantum pyhsics for all i will understand of it.
again i wish not to sound ungrateful but i just won't get what you are trying to explain to me if it doesn't follow my line of thinking or needs a complete rewrite of the program so far

weibullguy · 03-09-2007, 05:58 PM

No, I'm just suggesting that you (or your friend) install rsync and use that for incremental backups. Just trying to save you some time and heartache, but if you want to write a script that's fine too.

hoodedmanwithsythe · 03-09-2007, 07:14 PM

well thanks but he just said on skype that rsync is one that he has already tried and doesn't like.
what he wants is a program the matches his daily needs to a point not a program that just "does the job after a bit of hammering to fit the slot"
any way the final code is done for the comparitor part now anyway.
I just finnished it

ok so this thread has been inactive for a while but alas I have done some more work on the program so here is the new code.

I realize that my functions don't follow the number order but if function14 and function13 are not at the start then it comes up with a command doesn't exist error so i am leaving things as they are for now.

I need to know how to save the settings(that are held in variables at the moment)
so as they can be loaded again.
I was thinking XML but I am not sure how to retrieve the variables after I have saved them.
note. I am trying to run this as a NO DEPENDENCY PROGRAM. so please non of the XSH or similar. as this will mean that users will need to install things if they don't already have them.

edit: crashes on compare full stop I will fix this and swap the code for a working one within 30 mins.
edit: I did the above and then I went further, doing the save settings and a bit more still. so the below code is the finished code for now thanks for any help, suggestions are always welcome.
