for..each statement in CLI

I'd like to create a CLI batch file doing something like this:

For Each <file> in <directory> Do
{}

But i don't know how.

Anyone?

there's no such way

use spat, it's kind of similar: performs a command on a pattern of files

for recursivity, you have to use a recursive dir and rework the output to generate a temp script file that you execute. you can install the amiga version of sed, cut, etc... to help you with the replacements.

clumsy! i dunno about python on the classic amigas, but python just rules compared to all other scripting languages. even perl and bash don't stand a chance against it.

as for stuff i know of, there are implementations of csh and ksh (pdksh). I used the latter but proved kind of instable.

Code:

list >ram:script "<directory>" files lformat="<your_command> *"%p%n*""

execute ram:script

You can put multiple commands into lformat if you use *n as newline character.

For example:

Code:

list >ram:script Work: all dirs lformat="if not exists *"%p%n.info*"*n  copy envarc:Sys/def_drawer.info *"%p%n.info*"*nendif"

There are a couple of "foreach" programs on Aminet: http://aminet.net/search?query=foreach that might be useful?

I remember using foreach.lha in some scripts with DirOpus with good results. :)

Thomas, that worked like a charm!

Thanks!!!

By the way, I found AmigaPython which should do the trick as well.

Is there any way to do the following:

Code:

For each file named "foo" in this folder and all its subfolders do:

  some dos command like:

  delete the file

  or protect the file rwed

I tried some things including creating a script with "list" and "lformat" but got it working only for the top folder and not the subfolders.

I didn't try the "foreach" programs until now, but I'm not sure they can filter files by name from all subdirectories.
Any ideas how to write this?
Thanks :)

The list command has an "ALL" option which recursively scans subdirectories as well.

Thanks Thomas. Yes, that's what I thought too.
But "list foo all" lists all files of the directories named foo.
What I'd need: List all files named foo in all the subdirectories.
(Example case: 200 directories, some of them contain the file foo)

list all files p=foo

When I was previously looking for a foreach command I found:

Hey guys,

did the trick. Together with the lformat syntax from post 3.

For further reference:
Create a script with "command path/name" of all filtered filenames (including subfolders):

Code:

list >ram:script1 all files p=name1 lformat="command *"%p%n*""

execute ram:script1

So with this I could add the "s" flag to all the 407 files (in an equal number of subfolders) affected.

Code:

list >ram:script1 all files p=name1 lformat="protect *"%p%n*" +s"

Worked perfectly. Thanks a lot! :great
