Guys,

I'm a newbie for UNIX. I want to grep the last characters after the last "-" sign.

eg:

abcd-231-1-44 abcd-2341-22-55 abcd-1-23-6

In the above example. I want to grep just the last characters after the 3rd "-" sign. line1 it will be 44. line2 55 and line3 6

TIA

I am not familiar with all aspects of Unix/linux, though I use it everyday. I learned it by myself.

Here I have a simple question. I would like to have your kind helps.

In my file, there are this string ˆ@ˆ@ˆ@ˆ@ˆ@ˆ@ , I just want to delete all lines with this string. For example, using sed or grep command.

And I would like to know why there is such string occurred in my file.

I've just recently started using a Unix server, and I've been trying to figure out how to use the grep command to search a file of mine for all 4-letter words that begin with 's' (I don't care if its uppercase or lowercase) and have an 'r' as the third letter. I've tried many grep variations but none of them have returned properly with what I need. All help is appreciated, thanks.

Greetings!

please help on this.. i do not think the value of i is getting passed to the index(i).html section, as there is no output written into cloud file..
