Vista - regex - search - replace question

Hi,

I have and input text file containing data in the following format:

9.00; 1.00-; .00000;00; 25.00; 672;SC;006700014414841;107/09/14;
19.00; 22.00-; .00000;00; 205.00;
672;SC;006700014414841;107/09/14;

Is there any easy way to shift the negative sign (-) in the second column to
left? Output text should be like this:

9.00; -1.00; .00000;00; 25.00; 672;SC;006700014414841;107/09/14;
19.00; -22.00; .00000;00; 205.00;
672;SC;006700014414841;107/09/14;

Is there any easy way using regex or any search-replace technique?

Any help much appreciated.

Thanks,
PN

file with it? Overwrite the original? I'm assuming this is
line-per-line, and the general format doesn't change?

I've got something, but it isn't pretty yet...

PSH> $string
9.00; 1.00-; .00000;00; 25.00;
672;SC;006700014414841;107/09/14;

PSH> $string|`
foreach-object{$split=$split=$string.split(";")
$split[0]+";-"+$_.split(";")[1].trimend("-1").trimstart()}
9.00;-1.00

Ain't pretty, and I loose some of the spacing. A regex would be neater.

How do the original spaces fit into all of this? Do they need to be
preserved?

Mine is no pretty too, and there are still open questions as Marco wrote

$text="9.00; 1.00-; .00000;00; 25.00; 672;SC;006700014414841;107/09/14; 19.00;
22.00-; .00000;00; 205.00; 672;SC;006700014414841;107/09/14;"
$text.split(";") | foreach {$_=$_.trim(); if(($_[-1]) -eq "-"){ $_= ("-"+$_.replace("-",""))
}$_}

9.00
-1.00
..00000
00
25.00
672
SC
006700014414841
107/09/14
19.00
-22.00
..00000
00
205.00
672
SC
006700014414841
107/09/14

Regex is definitely a better solution.

Here's one way:

PSH>get-content data.txt|foreach-object{$_ -replace "(\d*\D*\d*)-;",'-$1;'}
9.00; -1.00; .00000;00; 25.00;
672;SC;006700014414841;107/09/14;
19.00; -22.00; .00000;00; 205.00;
672;SC;006700014414841;107/09/14;

(Pipe to out-file to save the output to a new file.)

(Thanks Lee Holmes for all the details you put in your books.)

# output to screen
(get-content file.txt) -replace '(\d+\.\d+)-', '-$1'

# output to new file
set-content newFile.txt ((get-content file.txt) -replace '(\d+\.\d+)-', '-$1')

${C:file.txt} = ${C:file.txt} -replace "(\d+\.\d+)-", "-$1"

This assumes the file is in the current working directory on the C:
drive.
