GNU grep has those flags. Use the link and get the required version.

Thank you so much. I havve been able to download the files. and I have used gunzip to unzip the files. I am new to this. I am trying to install this in my unix or AIX environment by running e.g by typing grep-2.5.1.tar at the command prompt and i get a permission denied error. I have used the chmod to give read write and execute access to the file.

What do I do next. I am really new at this.

Thanks.

Its a tar'ed file. You need to untar it.

tar xvf grep-2.5.1.tar

That will extract grep into the directory where you are running the command from. Since grep is a command run quite frequently, you might have to untar it into a directory which is there in the PATH. Or replace the existing non-GNU grep with the new one.

That decision is yours.

I did all that and I am still not able to use the flag.

this is the message I get when I do a man grep -A

[/home/user:]grep -A
grep: Not a recognized flag: A
Usage: grep [-E|-F] [-c|-l|-q] [-insvxbhwy] [-p[parasep]] -e pattern_list...
[-f pattern_file...] [file...]
Usage: grep [-E|-F] [-c|-l|-q] [-insvxbhwy] [-p[parasep]] [-e pattern_list...]
-f pattern_file... [file...]
Usage: grep [-E|-F] [-c|-l|-q] [-insvxbhwy] [-p[parasep]] pattern_list [file...]

What do I do? Please help

Thanks.

Post the results of
Code:
`which grep`

Looks like your grep is still the non-GNU grep.
