Top Forums Shell Programming and Scripting How to skip lines which don't begin with a number Post 302385774 by alister on Saturday 9th of January 2010 06:15:13 PM

Code:
awk '$1 ~ /^[0-9]+$/ {print >> "num"; next} {print >> "alpha"}' "$1"

The first "$1" is internal to awk and refers to the first field in the line. The second instance of "$1" is unrelated and is the shell positional parameter containing your file's name.

num=name of output file with numeric first fields
alpha=name of output file with all other lines
