For example if I have a file with the following 3 lines of text in it;

LINE1:  DESC_ 
LINE2:  DESC_,
LINE3:  DESC_

The strings ‘_ ‘ & ‘_,’ can appear anywhere in the line for LINE1 & LINE2 but only at the end of the line for LINE3.

Using a regex expression of ‘_[s,]’ I can easily match LINE1 and LINE2 but when I try to use an optional anchor like _[s,$] it does not fine the match in LINE3.

Suggestions?

Writing this in Windows PowerShell using the -match operator.

Test util:

target_strings.txt

#SAMPLE TARGET STRINGS


  DESC_ 
  DESC_,
  DESC_

Note: EOL immediately following the last line’s text

Clear-Host
$LINES = Get-Content -Path C:datadeployment_toolsTARGET_STRINGS.txt
foreach ($LINE in $LINES)
{ 
    if ($LINE -match '_ ') {write-host "$LINE matches regex '_ ' "} 
    if ($LINE -match '_,') {write-host "$LINE matches regex '_,' "} 
    if ($LINE -match '_$') {write-host "$LINE matches regex '_$' "} 
    if ($LINE -match '_[ ,$]') {write-host "$LINE matches regex '_[ ,$]' "} 
}

Looking for one regex statement that matches all 3 conditions.
