Parsing the Download Manager file

When using the Download Director from IBM, a file is created called This file is created in the directory that you download your files to. I have often found it annoying with the naming convention of files that I download to determine what a file is after I have downloaded it and left it for a while. I found that the file does contain pretty much all the info needed to identify the file information. So I thought I would create a quick perl script to parse the file. It is not the prettiest script, but it does what I need.

The script requires the path and file name to the file as an argument, and then creates a file called dlmgr.csv in the current directory.

There might be a bit of a bug - line 7 is missing a closing semi-colon.

Even after fixing that, it hasn't created the csv file in my directory :(

Great idea though!

Hi Robert,

Thanks for pointing that out. I guess when I cleaned up some stuff, I forgot to test it again. That will teach me to whip up a quick script ;)

It is fixed now.

How about a MDL for an Universal Agent which monitors my download directory?

I know I'm beating a dead horse, but:
1. I really like this script
2. More people should be leaving comments on this blog ;)

The titles of the files sometimes have commas in them - messing up the csv.
I added this line just before printing to fix that:

$filelist{$dlmgr_file}{title} = ~s/,/;/g;

Hi Robert,

Interesting, I guess I was lucky enough not to download one with a comma in the name. Of course that is something that I should have anticipated ;)

Anyway, I have added that to the file available for download.

Thanks again for the feedback.

I wrote a similar script last year out of the same frustration.

I wanted the files renamed such that they were abbreviated, yet maintained the product code and version info.

Its more "intrusive" because it actually renames the files, but a simple hack can take care of that.

jdsmedia@deantp1 /cygdrive/c/DownloadDirector
$ ls

jdsmedia@deantp1 /cygdrive/c/DownloadDirector
$ cat
..title=IBM Tivoli Enterprise Console (TME New Installations) V3.8 Multi

jdsmedia@deantp1 /cygdrive/c/DownloadDirector
$ /usr/local/bin/
PWD is /cygdrive/c/DownloadDirector
mv C473DIE.exe IBM_Tivoli_Enterprise_Console_TME_New_Installations_V3_8_Multi_C4
