  $old = 'src="*_file/image001.gif"'   $new = 'src="http://www.website.com/image001.gif"'   #change get-childitem folder or choice get-childitem c:\signatures\*.htm  | {$_ -is [io.fileinfo]} |   % {   (get-content $_.fullname) -replace $old, $new | set-content $_.fullname  write-host "----- working   ----------"  write-host "processed: " + $_.fullname   }

in regular expression, dot matches character.  + quantifier means "one or more".  ? makes "lazy" match, means "only as need match", , may or may not necessary depending on data looks like.

regex matches "greedy" means take as can. 

$string = 'abcdefg abcdefg abcdefg' $string -replace '.+defg', '123'

will return

'123'

the .+ matched way the last 'abcdefg'.

$string = 'abcdefg abcdefg abcdefg' $string -replace '.+?defg','123'

will return

'123123123'

the .+ matches as needs satisfy match.
