Hi.... I am new to perl.... and after reading up on how to write scripts. I find I am not able to do this simple thing. I can do it in Excel but I would like a script in perl to do the same thing. Here's the details I have a file....... date:col1:col2:col3 20010102:21:45:25 20010103:14:20:15 etc......... 20010124:10:8:10 What I would like to do is find the 10 day average of col3 and the 5 day average of col2...... and write all of this to a log file......like this... "Name of file" average col2 value of last entry col2 average col3 value of last entry of col3 ( last entry is the last line in the file ie 20010124.. Could someone please have a look at this and help me out here...??? Thank you Joachim
