Later i encountered an error and thought that is related to to the substr function. But looks like it caused by something else.

Thanks for the response !!

Similar to that I am also trying an awk array and wanted to check if the array value match string "{5:{" , replace with 5: and assign it back to same array and print it.

But below code is not working its not able to replace the array value , instead its assigning whole command to msg_arr[i] and printing it

any solution for this?

Code:

              for (i=msgtkn_20_lnno; i<msg_lnno;)
              {
                if(msg_arr[i]  ~ /^{5:{/ )
                {
                tag5_before_value= msg_arr[i];
               msg_arr[i]="echo $tag5_before_value | sed 's/{5:{/5:/g'";
                printf "after conversion is %s/n", abc > "LOG.txt";
               print msg_arr[i++];
               }
                else
                {
                  print msg_arr[i++];
                }

              }

as soon as i use "`" its giving me syntax error

Please do not use one thread to discuss two topics. The second topic in this thread is already being discussed in the thread sed inside the awk script to replace a string in the array. Do not continue that discussion here!

pset_assign_pid

pset_assign_pid(1)					      General Commands Manual						pset_assign_pid(1)

NAME

       pset_assign_pid - Assigns a process ID to a processor set

SYNOPSIS

       /usr/sbin/pset_assign_pid [-x] pset_id pid [pid...]

OPTIONS

       Assigns exclusive use of the target processor set to each specified process identification number.

DESCRIPTION

       The  pset_assign_pid  command  assigns  one or more process identification numbers to an existing processor set.  The pset_id variable is a
       unique integer that identifies the processor set and is returned by the pset_create command. The pid variable is the process identification
       number, which is a unique integer that identifies the process. Each process identification number that is assigned is removed from its cur-
       rent processor set.

       Use the -x option to assign exclusive use of the processor set.	If the processor set is already in use, a message is  displayed,  and  the
       command	terminates  without  performing the assignment.  If the exclusive assignment succeeds, new requests by other processes for assign-
       ments to the specified processor set (pset_id) are denied.

SEE ALSO

       Commands:  pset_destroy(1), pset_create(1), pset_assign_cpu(1), pset_info(1)
