Please refactor this code to be more efficient. Thanks!

if [ $1 -eq $column then if [ $fileExist -ne 1 ] #check if temp file exists then fileExist-1 if I $x -eq $columnt then echo $sum > $tempo4 #if the space should be a value #then print the value to the file else printf "%s\t" $sum > $tempo4 #else place a TAB in the file Fi else #since the file is already there, we will append from now on if I $x -eq $columnt then echo $sum >> $tempo4 #putting a data value in the file else printf "%s\t" $sum >> $tempo4 #placing a tab fi fi fi
