Remove spaces and tabs at the beginning of all lines

[ftpaccess]

I have records which have spaces in front of them:

[space]Mike Dawson
Allen toole
[space]Chasey White
Robert Weyes

I want to bring them to this format:

Mike Dawson
Allen toole
Chasey White
Robert Weyes

There is trim trailing spaces but no trim preceding spaces.

Run an UltraEdit regular expression Replace All searching for %[ ^t]+ and an empty replace string.

Or if you prefer Unix or Perl regular expression engine use as search string ^[ \t]+ and also an empty replace string.

This can be performed without writing a regular expression. You highlight the text and then select Format, Remove Indents and pick a number larger than the biggest gap, say 20 or so. This will move all of the lines flush to the left margin. You won't lose any characters except tabs or spaces from the beginnings of the lines, even when they are already flush.
