How to get the line number from while read

I have a file TXTPROCESS.TXT.20071129 in which line 1 contains the file name and rest of the records are data.

The file data looks like this:


From line 2 onwards the first 4 characters defines individual process. What I need to do is read through the line and check if it is not line 1 then exectute individual process. My problem is I don't know how to check the line number. This code gives me one line at time for all the lines.

cat TXTPROCESS.TXT.20071129 | while read LINE
echo $LINE

Any idea?

its much more comfortable with awk

try this,

awk '{ print $0, NR }' b

this prints the content read from a line and the line number

to skip first line and print only the first 4 characters from the remaining
awk ' NR != 1 { print substr($0, 1, 4) }' b
