append data to each line

Hi guys,

I need to investigate a memory leak on a solaris server, so what I have done is pmap'd each process on the system with a script which tar'd the directory every hour in cron. Now I need to write a script to process the pmap data.

So what I have is about 100 directories
[root@localhost ~]# ll pmaptest/pmapdata2009101
pmapdata20091012122344/ pmapdata20091013080000/ pmapdata20091013230000/ pmapdata20091014140000/ pmapdata20091015050000/ pmapdata20091015200001/
pmapdata20091012180000/ pmapdata20091013090000/ pmapdata20091014000000/ pmapdata20091014150000/ pmapdata20091015060000/ pmapdata20091015210000/
pmapdata20091012190000/ pmapdata20091013100000/ pmapdata20091014010000/ pmapdata20091014160000/ pmapdata20091015070000/ pmapdata20091015220000/

inside each directory is the output from the pmap on that process
[root@localhost pmapdata]# ll
total 1172
-rw-r--r-- 1 root root    21 2009-10-12 17:00 pmap0.txt

-rw-r--r-- 1 root root  7652 2009-10-12 17:00 pmap16406.txt
-rw-r--r-- 1 root root  6032 2009-10-12 17:00 pmap16436.txt
-rw-r--r-- 1 root root  6032 2009-10-12 17:00 pmap16438.txt

the format of the filename is pmap<pid>.txt

inside each file looks like this
[root@localhost pmapdata]# cat pmap985.txt

What I am interested in is the anon for each pmap is the total at the bottom for the Anon column. I want to output this data in csv format for use inside an excel spreadsheet where I can graph the data.

So the output format need to be


I have started writing a script to do that which is below, but I cant figure out how I will get the pid and mem total appended to the same line each time?
ls -l /root/pmaptest/ | awk '{print $8}' > /root/pmapdirs.txt
for dir in `cat /root/pmapdirs.txt`
cat /root/pmaptest/pmapdata$dir/var/tmp/pmapdata/psefo.txt | awk '{print $1}' > /root/pmaptest/pmapdata$dir/var/tmp/pmapdata/pids.txt
for pid in `cat /root/pmaptest/pmapdata$dir/var/tmp/pmapdata/pids.txt`
tail -1 /root/pmaptest/pmapdata$dir/var/tmp/pmapdata/pmap$pid.txt  | awk {'print $5'}

for i in `find /root/pmaptest -type f -name pmap*.txt`
  PID=`echo "$i" |awk -F/ '{print $NF}' |sed -e 's/^pmap//' -e 's/\.txt//' `
  anonmemtotal=`tail -1 $i |awk '{print $5}' `
  echo $PID "," $anonmemtotal

you can create another script (or add one more function) to merge anonmemtotal into same PID.

If I understand what you are looking to do, this awk script will take a list of pmap files of the form you presented and print a csv line with the pid and anon values found in all the pmap files. The anon values are in the order of the pmap files given on the command line.

FNR == 1) {

        getline   # skip to the pid
        this_pid = strtonum($1)
        if( this_pid in pid_list)
                pid_list[this_pid] = pid_list[this_pid] ","     # add a comma
                pid_list[this_pid] = "%d,"              # set the format string
/^total/ {              # look for total line

        pid_list[this_pid] = pid_list[this_pid] $5      # add anon total

        for( i in pid_list )
                printf pid_list[i] "\n" , i

To use it, put the above code in a file (pid.awk in my example).
Then use a command of this form

awk -f pid.awk <list_of_pmap_file>

The <list_of_pmap_file> should be a wildcard spec or back tick command to produce a list of files in the order you want them processed.
