I'm trying to re-create the script using one call to exiv2. "-Pnv"/"-Pkv" and grep are no good, because the output of the former is a block of text when set to a variable. So I have it writing "fullfiledata" to an ASCII file thus:
Calling any part of that back, I'm reminded of the problems I had when first writing a script to perform this function.
On the command line, as two separate lines, these will return cate2 as empty if indeed there is such a line as "Iptc.Application2.Category" in file x. Likewise for every variable set to a tag by grep to the end of the set of conditionals (the other 7 tags Exiv2 grepped in the original script).
Where the problem occurs is in assembling the variable iptc: something wants to ignore any and all empties and stock it with the "if set but empty" value of foo2. Printing iptc to a file, then, means I'm getting a "false report" on all the files from the first one in list.txt to the last, (or until I get so annoyed I terminate the script, which is more likely at this point).
It has so far made no difference to include "else" statements setting the value of a particular second variable to nothing.
Here's the revised code, letting out all possible stops and (I think) allowing for most possible combinations of missing fields.

I wrote a very simple script that matches combinations of alphabetic characters (1-5). I want to use it to test CPU speeds of different hardware/platforms. The problem is that on multi-core/processor systems, only one CPU is being utilized to execute the script. Is there a way to change that?... (16 Replies)
Hello everyone,
I am struggling a bit with a batch script that I need to run in cygwin. I work in winXP and I had to write some awk scripts to do some file manipulation, and now I would like to automate the process by just running a batch file so that my colleagues can use it easily.

Hi guys,
I'm basically looking for some help with a bash script I've written. It's purpose is to assign process to individual CPU cores once that process hits 15% CPU usage or more. If it drops below 15%, it's unassigned again (using taskset).
My problem is that I can't think of a way to... (2 Replies)
I'm using Notepad++ to edit my BASH scripts and using CYGWIN to run them from Windows7.
In Notepad++ there is a 'Run' capability. How do I get this to run my scripts directly without having to enter the script name from the Cygwin command line? (3 Replies)
As stated, I am looking into keeping my backup drive unmounted in normal windows use. Partly this is to address threats like cryptolocker. Since one of my backup drives is an internal drive, it will not likely afford any protection from such a threat. I am thinking of adding code to my rsync script... (5 Replies)

Needless to say that the windows box has Cygwin... (7 Replies)
