Methyl,

Data get appended to the sa15 file automatically.....we have filter and send only last 48 hours data. every row is hourly data ie., tail -48.

How can i schedule it to run every hour without scheduling it in cron...as we dont have access to cron... any other way out (using sleep, autosys etc).
Pleas suggest....

Other correspondents have replied to your questions on your other posts. I've lost the plot. Any chance you can consolidate the whole lot into a private document. While doing this the lightbulb might light before your project work is due in.

Hi i am not sure how much time gain you are going to get

but you can provide file name as argument to grep you dont have to cat file every time same goes with awk

Code:
    
    cat failed-logins-$i.txt | grep -i invalid > invalid-failed-logins-$i.txt
    can be => grep -i invalid ailed-logins-$i.txt > invalid-failed-logins-$i.txt

    cat failed-logins-$i.txt | grep -v invalid > valid-failed-logins-$i.txt
    can be => grep -v invalid failed-logins-$i.txt > valid-failed-logins-$i.txt
  
    cat valid-failed-logins-$i.txt | awk '{a[$1 FS $2 FS $9 FS "\t"$11]++} END {for (i in a) {print i "  =  " a[i] }}'
  
      can be => awk '{a[$1 FS $2 FS $9 FS "\t"$11]++} END {for (i in a) {print i "  =  " a[i] }}' valid-failed-logins-$i.txt
    
    cat invalid-failed-logins-$i.txt | awk '{a[$1 FS $2 FS $11 FS "\t"$13]++} END {for (i in a) {print i "  =  " a[i] }}'

Correct me if i am wrong
