Am trying to use the sed command to remove all the text before the first numeric character in all the lines, by using the following

sed 's/.*[0-9]//' temp1.txt

However, it is removing all the text up to the last numeric character.

  • you should add sample input/output to clarify whether or not you want to remove the first digit as well... you text says before but the code you tried removes the digit – Sundeep Oct 28 '17 at 15:25

this is due to eager algorithm of sed.

use:

sed 's/^[^0-9]*//' temp1.txt

where

  • ^ begining of line
  • [^0-9] any char but 0-9
  • * multiple time
  • 1
    This will also remove the first numeric character, if this is not desired, leave off the second [0-9] – crater2150 Oct 28 '17 at 15:17
