UNIX for Dummies Questions & Answers

Hi guys ,

I think i have completely lost touch with awk ... but now i need it deseparatly ...

my problem is for each line in the line i have to check if the first 2 charactes are 'A4' and if they are 'A4' then cut the characters

from position 11-16 from that line ...

In the meantime i will try to recall my awk concepts .. hate myself


Thanks in advance

A few questions:
What does the data look like? How is the file delimited? Are there delimiters or is it one stream of data (No spaces)? I dont write too much awk! Here is a start. ($STRING is your file name!)

echo $STRING | awk '
{
for (i=0; i<=NR; i++)
if (toupper(substr($i,0,2) ) == "A4")
{
#Add stuff here
my_stuff=substr($i,11,5)
print my_stuff >> "awk-log-file.dat"
}
} '
