Question

I’ve got the below code working, in KSH but it takes the jobs a while to run generating .tmp1 it’s slow in the echo $LINE | cut -f 2,4 -d " " >> [file] command, but I don’t know why.

I’m guessing it’s because it’s due to the echo but I don’t know; and I don’t know how to re-write it to speed it up.

echo "Generating on zTempDay$count.tmp"
while read LINE
do
#Use Cut to trim down to right colums
#cut -b 11-26 $LINE
#mac=  cut -b 39-52 $LINE
#vlan= cut -b 62 $LINE
#This line pegs out the CPU - want to know why
echo $LINE | cut -f 2,4 -d " " >> zTempDay$count.tmp1
update_spinner
done < zTempDay$count.tmp
#Remove 'Incomplete' Enteries
#numOfIncomplete=grep "Incomplete" zTempDay$count.tmp1 | wc -l
sed -e "/Incomplete/d" zTempDay$count.tmp1 > zTempDay$count.tmp2
#Use sort to sort by MAC
#Use uniq to remove duplicates
sort +1 -2 zTempDay$count.tmp2 | uniq -f 1 > zTempDay$count.tmp3

#Format Nicely
tr ' ' '\t' < zTempDay$count.tmp3 > zTempDay$count.tmp4
##Want to put a poper progress bar in   if program remains slow
#dialog --gauge "Formatting Data: Please wait" 10 70 0
#bc 100*$count/$maxDaysInMonth

Answer 1

*awk '/Incomplete/ {next} ; 
{print $2 "\t" $4}' zTempDay01.tmp | sort +1 -2  | uniq -f 1 > outfile* 

works like a charm thanks to Shellter’s help. Thank you! 🙂
