------------------------------------------------------------------------------------------------ on trimLeadingWhiteSpace(str) set cmd to "sed -nE 's/^[ ]*//p'<<<" & quoted form of str do shell script cmd return result end trimLeadingWhiteSpace ------------------------------------------------------------------------------------------------
set str to " Some Text 1 Some Text 2 Some Text 3 Some Text 4 Some Text 5 Some Text 6
Some Text 7 "
trimLeadingWhiteSpace(str)

This is pretty fast.
Personally I'd use the Satimage.osax's regular expressions for speed and flexibility.
