retreiving and assigning values and manipulating string in a for loop - Page 3

There's one more bump in the code

, the increment of n in the loop should be after the echo statement.

i.e. and also added some echos to see what values are going into the array..

Code:

 
IFS=""
event=`psg proc_s | grep de0`
for line in $event
do
  echo $line
done
 
 
n=0
psg proc_s | awk '/de0/{split($5,a,":");print a[2]}'| while read s
do
  Sam[$n]="$s"
  n=$(( $n + 1))
  echo ${Sam[$n]}
  echo ${Sam[0]}
   echo ${Sam[1]}
   echo ${Sam[2]}
   echo ${Sam[3]}
   echo ${Sam[4]}
    echo ${Sam[5]}
  # other code
  # ....
done
echo "time is ${Sam[5]}"
echo $n

and got the output as five blank lines..
echo ${Sam[$n]} seems to be printing blank lines.

Output:

crmcint 15326 1 0 14:16:27 ? 0:01 proc_s de081.c
crmcint 16428 1 0 14:35:49 ? 0:00 proc_s de08.c
crmcint 10272 1 0 13:12:48 ? 0:06 proc_s de01.c
crmcint 20229 1 0 15:06:23 ? 0:00 proc_s de05.c
crmcint 18285 1 0 14:51:38 ? 0:00 proc_s de083.c
crmcint 18902 1 0 14:57:02 ? 0:01 proc_s de083p.c
...

Hello

is it possible in the above code to get the number of splits that have happened over her..
suppose if the above code goes like this

psg proc_s |awk -F" " '{print all fields }''| while read s
do
n=$(( $n + 1))
Sam[$n]="$s"
done

now in case if i do echo ${#Sam[0]} it gives number of charachters in the Sam[0] array..what if i have to find number of words...i.e to get the
number of spilts per line..how can it be done

If I understand you correctly, the following code should do the trick:

Code:

echo "${Sam[0]}" | awk '{ print NF }'

The split function returns the number of the elements of the array:

If the fifth field starts with an upper case letter, return the value of the ninth field, otherwise return the value of the eight field.

i don't see why not - would not hurt to try it.
