I'd like to redirect output from this command:
ps -eo pid,comm,cmd,start,etime | grep -i qtcreator > file.txt
When I try it, I've also output command grep -i example
2018 qtcreator qtcreator 08:11:50 01:05:00 <br> 5513 grep grep -i qtcreator 09:16:50 00:00 How can I resolve this problem?
You can solve it by editing your command like this:
ps -eo pid,comm,cmd,start,etime | grep -i qtcreator | grep -v grep > file.txt In this way you are exclude the ward grep from the result of the first grep
I think a more cleaner way would be to use pgrep with ps:
ps -p $(pgrep <program-name>) [iahmad@localhost]$ ps -p $(pgrep sendmail) PID TTY STAT TIME COMMAND 32373 ? Ss 0:59 sendmail: accepting connections 32383 ? Ss 0:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue
