Top Forums Shell Programming and Scripting Extract all first numeric character from a string
# 8  
Old 04-18-2015
Note that OP specified a requirement to extract all the first numeric characters, which is different from "all numeric characters that appear at the start of the line" ..
So it would seem that something like this should be more appropriate..
Code:
sed -n 's/^[^0-9]*\([0-9][0-9]*\).*/\1/p' file
