[SOLVED] Dos programming

niiiro · 01-02-2011, 07:20 AM

Hey Guys,

I'm writing a small script in Batch and I would like to code something that it will enter various directories, do some actions, leave directory and enter the next one. these directories names change often so I can't set permanent names.

will appreciate your kind help.

Regards,

Nir.

Just store these directory names in other file. You only need to choose best format for your needs. The easiest is to write them as bash variable, separating by IFS environment variable:

Code:

DIRECTORIES='/tmp/dir1 /home/dir2 /usr/bin/dir3'

and saving file for example "directories.conf"
and then in the script you refer it:

Code:

#!/bin/bash

DIRECTORIES=''

source ./directories.conf

for DIR in $DIRECTORIES ; do
    echo "Processing: $DIR"
done

Was there any reason to remove this thread from the zero replies list?

eSelix, I believe the OP wants to do this in a DOS batch script (i.e. under Windows), hence the title of their post..

Yes, since there was no real question I assume that the OP will come up with one in the near future. At least this is how I interpret

And since the OP is asking a DOS question - and it has happened that similar requests were (falsely) 'shot' down in the past just because not being Linux related - I thought it was necessary to reaffirm the OP that his question is valid nonetheless and in the appropriate forum.

@OP: If you actually do have a question at this point then please post what you have tried so far and where you are stuck. Then we can see if we can help you solve the issue.

Actually, there may be a way to parse the output of the dir command to get your list of directories. It would be simple if they were all subdirectories of the folder, and that folder contained no files or shortcuts.

We have to little information to determine an optimal way to help. Can you provide more detail?

How can the script know which directories to enter?

Just out of curiosity, why aren't you doing the script in Powershell?

Lots of activity in here..

anyway.. here is the directory tree so you guys get a better view:

Code:

├───CP1 raw data
│   ├───K33786-10-CP1
│   ├───K33787-10-CP1
│   ├───K33789-10-CP1
│   ├───K33895-10-CP1
│   ├───K33897-10-CP1
│   ├───K33903-10-CP1
│   ├───K33933-10-CP1
│   └───KL0985-10-CP1
├───CP1 summary data
├───CP2
│   ├───K33786-10-CP2
│   ├───K33787-10-CP2
│   ├───K33789-10-CP2
│   ├───K33897-10-CP2
│   ├───K33905-10-CP2
│   └───K33933-10-CP2
├───Finish Line
└───WAT

what i'd like to do is as follows:

* While being under "CP1 raw data" directory, the script will enter each directory (those directory names change often and they get their name randomly. just as seen in the directory tree.) and preform a few actions such as extraction and packing. as for these actions - i have a code written already. after preforming these actions, leave the current directory and move to the next one.

Hope that clears things up a little...

eSelix, thanks but thats irreverent since I can't tell what would be the exact directory name in advance.
Dugan, I don't know powershell at all so I didn't even try getting into this.

Code:

@echo off
setlocal

for /r .. %%d in (.) do (
  cd %%d
  REM process here
)

Is my syntax ok...? because it doesn't seem to enter sub-directories.

Are you asking if the syntax that you said to ignore is okay?

It enters subdirs for me:

As an old DOS dinosaur, i have met this kind of problem many times. The problem here is that DOS batch processes are inherently simple, with no built-in ability to perform bash-like logic.

In my opinion, eSelix got you started in the right direction by telling you to store the directory names in a text file. Change the text file every time the directory names change. But that's tedious at best. So let me ask you: do you have a DOS based text editor that includes some sort of macro capabilities? (My favorite DOS text editor was QEdit by Semware.) If you have something like that, here's what you do:

Pipe the DIR command into a text file

Code:

DIR *.* >> mybatch.bat

Then use the text editor's macro to change each line into the appropriate command using the directory name on that line as its argument. Run it as a batch file, and you're done.

If you don't have a macro-capable text editor, let me know, and we'll take it from there.

it works perfectly!

I would still like to have a few features from that editor in a simple *nix text-mode editor. Best editor, ever.

I used to use a package of Unix-like tools, including a Bourne shell-ish, that would provide much of the functionality that we take for granted in Linux these days, but in DOS. I remember it was a commercial package, but I seem to recall that there was also a free version, or perhaps the commercial product went 'free' when it neared end-of-life. I cannot remember the name of it. Maybe the OP can still find such a toolkit to solve the problem.

I think I'll dig out some of my 20 year old Dr. Dobbs mags, and see if I can find one of their advertisements.
