you can try array[2] == ""

ghostdog, this comparison to not overwrite existing files is not working
my current whole script looks like:

Code:
/HandleRequest.*AService/{  
    if(b=match($0,"xml")) {
      xml=substr($0,b-2)
      # print $0
    }
    else {
      next
    }
         
    n=split($0,line," ")
    m=split(line[5],file,"|")     
      
    if (file[2] ~ /^[0-9]/) {
       filename=file[2]
       
       if ((getline < filename) == -1) {
          n=split(filename,array,"-")
          
          if (array[2] == "") {
            print xml > filename".xml"
          }
          else {
            # print array[2]
            cmd="mkdir -p " array[2] 
            # print cmd
            cmd | getline result
            close(cmd)
            print xml > array[2]"/"filename".xml"
          }
       }
    }
}


Any suggestions?

Once again, I apologize for my poor specificity.

Each time the log is parsed, the existing xml files are overwritten.

I would prefer that as soon as the filename is determined while reading through the log, that if the filename already exists then it moves on to the next suitable line without any further parsing of the previous line.

The problem I see with the if statement as it is (that is used to prevent overwriting), is that it does not look in the subdirectories.

How can I adjust the statement, or rearrange the code to fix it, and prevent overwriting existing files?

i am sorry i still couldn't get you. but let me try one last time
this snippet only executes when the file does not yet exists, so if you want to skip when it exists, you can use next:
Code:
    if ((getline < filename) == -1) {
          n=split(filename,array,"-")
          
          if (array[2] == "") {
            print xml > filename".xml"
          }
          else {
            # print array[2]
            cmd="mkdir -p " array[2] 
            # print cmd
            cmd | getline result
            close(cmd)
            print xml > array[2]"/"filename".xml"
          }
       }
       else {
            next
       }

if its still not what you want, maybe you can try the other methods the good ppl here have posted before. And also , you don't really have to do everything in awk if you are not comfortable...using the shell is also fine.
