i want to run top command every 1 second interval and want to store the output in a text file. so in every 1 second interval my text file should be overwritten by the new fresh output data.
my top command is :
top -d -1
Question is :
How do i store the output in a text file and how do they be overwritten by the fresh output data in every 1 secs interval ?
top -d 1 > logfile
does not do what he wants (doesn't even produce correct results), neither does
top -d 1 -b > logfile
since the new content is appended every second, nothing is overwritten (except for the content of logfile at the beginning).
hi,
it is not working ! it is not overwriting at all . its appending !
command was top -d -1 >log.txt
i just need to get the fresh data every 1 secs interval from the log.txt file. so, i told it to be overwritten the content . i dont like append, if i append my file is going to be larger and t would be difficult to read the last status .
but surprisingly. i ran the above command and got my file appeneded to 1.4 MB !! . then i stopped the execution by CTRL+C .
