Hello

I'm stuck trying to solve this KSH issue and I'm hoping someone out there can offer some suggestions.

I want to read lots of large .gz files one line at a time in order to compare its Error entries with a list of known errors. I can't simply do "foreach ERROR do gzcat *.gz |grep ${ERROR}" because I would have to parse every single large log file for each of the known errors and the time to do that would be days. So I want to parse the log files only once, read each line, compare the error, and increment the error count for each error. I know how to do most of this except the part about processing one line at a time from a .gz file.

I came up with something like this but it's not working. It's outputing all the lines in the file, instead:

 
while read file_line
do
ERROR=`grep ^ERROR ${file_line}`
print ${ERROR}
done < `gzcat 080803.gz`
