Cut an output
Hi everyone, happy new year

I have the following output:
2503 nteath 20 0 4892 312
2503 nteath 20 0 5872 312
2503 nteath 20 0 6852 312
2503 nteath 20 0 7832 312
2503 nteath 20 0 8812 312
2503 nteath 20 0 9792 312
2503 nteath 20 0 10772 312

and i want to keep only the highlighted (bold) column.
I used
cut -d' ' -f12
but in this way i lose the last number ( 10772), i think because it's 5-digit.
How can i keep all the numbers in the column?

I presume you mean
Code:
cut -d' ' -f5

It may be that cut does not show the last value because the last line of the input file is missing a closing linefeed (\n) and your version of cut cannot handle that. See if this makes a difference:
Code:
printf "\n" | cat infile - | cut -d' ' -f5

or try this instead:
Code:
awk '{print $5}' infile

Code:
cut -d' ' -f5

This returns only blank fields.

Let me be a little more clear:
i have the command:
Code:
top -d 1.0 -p $PID -n 10 | grep $PID

which returns information about a process. This looks like :
Code:
 3260 nteath    20   0  4892  312  240 S  0.0  0.0   0:00.00 dummy              
 3260 nteath    20   0  5872  312  240 S  0.0  0.0   0:00.00 dummy

 3260 nteath    20   0 10772  312  240 S  0.0  0.0   0:00.00 dummy              
 3260 nteath    20   0 11752  312  240 S  0.0  0.0   0:00.00 dummy              
 3260 nteath    20   0 12732  312  240 S  0.0  0.0   0:00.00 dummy              
 3260 nteath    20   0 13712  312  240 S  0.0  0.0   0:00.00 dummy

When i use:
Code:
top -d 1.0 -p $PID -n 10 | grep $PID |cut -d' ' -f12

the output is:
4892
5872
6852
7832
8812
9792
It seems i can't get the 5 digit numbers.

---------- Post updated at 05:44 AM ---------- Previous update was at 05:40 AM ----------

Code:
top -d 1.0 -p $PID -n 10 | grep $PID | awk '{print $6}'

This seems to work great Smilie
Thank you.
