Linux

I would like to create an alias on my 'grep' command on Linux.

Generally when I use 'grep', I do as follows:

Code:

$ ps -ef | grep -i ntp | grep -v grep

My question is how can I simply run the 'grep' command as shown above and it also include the -i / -v switches as well w/o me having to enter them in manually every time?

Could I suggest that you use the functions of the shell to work with patterns. Something like this would sort your issue:-

Code:

ps -ef | grep -i nt[p]

The string actually searched for is ntp but your process doesn't look like that, so it is excluded.

The expansion rules will define the [p] bit as a range of characters of, um, well the letter p only. It's a one character range as opposed to:-

Code:

ps -ef | grep nt[a-z]

which will give you all processes containing any of the the strings nta, ntb, ntc, ntd, nte......



I hope that this helps,
