Try this:

Code:
psg ksh | awk 'BEGIN {n=split($0,arr," ")} {
  for (i=1;i<=n;i++) {
    print arr[i]
    print length(arr[i])
  }
}'

}'


Its executing without errors but no output.

Ok...., if this is the output of the command psg proc_s:

Code:
jnunly 10612 1 0 13:18:21 ? 0:02 proc_s gsCTrip.c
crmcint 15326 1 0 14:16:27 ? 0:01 proc_s de08.c
crmcint 16428 1 0 14:35:49 ? 0:00 proc_s de01.c
rscle 3481 1 0 Apr 13 ? 0:01 proc_s dt07.c
crmcint 22356 1 0 15:27:21 ? 0:00 proc_s rune.c
crmcint 10272 1 0 13:12:48 ? 0:06 proc_s de03.c

What should be the desired output?

pid uid and command name for each listed process.
ex: pid=10612 uid=jnunly command=proc_s

Sorry , i did not check your script completely , other than the for loop.

try this :

Code:
awk '{ print "pid="$2 " uid="$1 " command="$(NF-1)}' file1.txt

If there are more than one argumnet for the command than NF-1 Would not return the command name..

example
jnunly 10612 1 0 13:18:21 ? 0:02 proc_s gsCTrip.c arg1 arg2 arg3

then NF-1 Would be arg2 which is not command name..
moreover i donot want to put this values in file..would be in a variable which would be used in if else blocks.

Change the argument number accordingly (i.e replace $(NF-1) with $8.

I did not understand
Code:

what it mean ?...
