Hello all;

I've been having trouble completing a script (bash) because I can't get past the issue of finding a line in a file. For example, I have a file like this:

ddmmmyyyy Lon Lat
24may2003 -100.0 24.1
25may2003 -100.1 24.0
28may2003 -99.5 23.2
....etc
05jun2003 -97.0 22.7
EOF

I'm making a loop, and I need a way to call a line number without specifying what the line contains (i.e., grep doesn't work). Here's what I had in mind:

n=2
While (something that makes the loop infinite); do
day=`command line${n} word1
